Frequently Asked Questions - 57153 ASTRALPOOL

What should I do if the pump is not delivering chemical?

First, check that the suction and discharge valves are clean and not blocked. Also inspect the filter for clogging. If the valves are swollen, replace them with the correct material (e.g., Viton, EPDM, etc.). Ensure the pump is primed properly.
Tip: Remove the suction hose and check for obstructions.

How do I prime the metering pump?

Before finalizing installation, prime the pump by following the sequence in Fig. 8 of the manual. You can also use a syringe to suck liquid from the discharge nipple while the pump operates. If your pump has an air bleed valve, unscrew it until air escapes.
Caution: Always disconnect power before handling chemical lines.

What power supply is required for the AstralPool 57153?

The standard power supply is 230 V a.c. 50 Hz single phase. Optional supplies include 240 V 50-60 Hz or 110 V 50-60 Hz single phase. Check the rating plate on your pump for exact specifications.
Safety: Use a circuit breaker with at least 3 mm contact gap.

How often should I maintain the pump?

Regular maintenance is minimal. Check the pump every 6 months: inspect the pump head, screws, bolts, and seals. For aggressive chemicals, check more frequently. Clean the filter and valves periodically. The manual recommends cleaning hydraulic parts as needed based on application.
Note: No lubrication required.

Can the pump be used for sulphuric acid dosing?

Yes, but with precautions. Replace the PVC suction hose with polyethylene hose. Ensure no water remains in the pump head to avoid violent reactions (mixing with sulphuric acid generates gas and heat). Turn the pump upside-down for 15–30 seconds to drain.
Warning: Always use appropriate personal protective equipment (PPE).

What does the level alarm indicate?

On models with level control (optional), when the chemical tank is empty, the display shows 'FAO' (or 'RLI' on VFT models) and the pump stops with an optical and sound alarm. This prevents the pump from running dry.
Action: Refill the tank and reset the pump.

How do I set the pump for proportional dosing with a 4-20 mA signal?

For EXACTUS CC/M models: press the function button to enter Set 1 mode to define minimum mA input (e.g., 4 mA) and minimum flow. Then Set 2 mode for maximum mA (e.g., 20 mA) and maximum flow. The pump automatically starts in 'METER' mode after programming.
Example: 4 mA = 0 l/h, 20 mA = 10 l/h.

What should I do if the pump pulses but no chemical is injected?

This is often due to blocked or worn valves. Dismount the suction and discharge valves, clean them, and replace if necessary. Check the filter for clogging. Also ensure the injection valve sleeve (no return) is not removed.
Note: If using aggressive chemicals, verify material compatibility.

Is it safe to use the pump with corrosive liquids?

Yes, the pump is designed for aggressive chemicals. The standard pump head is polypropylene (optional PVC, 316 SS, PTFE). Diaphragm is PTFE. Valves are Viton (FPM) standard. Always check chemical resistance chart for the specific liquid. Adhere to safety precautions: wear gloves, goggles, and ensure proper ventilation.
Warning: Do not use with hazardous liquids unless all safety measures are followed.

How do I install the injection valve?

Select an injection point on the plant pipe. Fit a 3/8" female BSP steel connector. Screw the injection valve (with gasket) onto the connector. Connect the discharge hose with the provided tube nut. The sleeve (non-return) inside the valve must not be removed. Refer to Fig. 9 in the manual.
Tip: Keep the injection point at least 1 meter away from electrodes.

• Keep this manual in a safe place, so that it will always be available for further consultation.
• The pump complies with EEC directives No.89/336 regarding "electromagnetic compatibility" and No.73/23 regarding "low voltages", as also the subsequent modification No.93/68.

N.B. The pump has been constructed in accordance with best practice. Both its life and it electrical and mechanical reliability will be enhanced if it is correctly used and subjected to regular maintenance.

1.1 - WARNING:

Any intervention or repair to the internal parts of the pump must be carried out by qualified and authorized personnel. The manufacturers decline all responsibility for the consequences of failure to respect this rule.

GUARANTEE: 2 years (the normal wearing parts are excluded, i.e.: valves, nipples, tube nuts, tubing, filter and injection valve). Improper use of the equipment invalidates the above guarantee. The guarantee is exfactory or authorized distributors.

1.2 - SHIPPING AND TRANSPORTING THE PUMP

The pump should always be moved in a vertical (and never in a horizontal) position. No matter what the means of transport employed, delivery of the pump, even when free to the purchaser's or the addressee's domicile, is always at the purchaser's risk. Claims for any missing materials must be made within 10 (ten) days of arrival, while claims for defective materials will be considered up to the 30th (thirtieth) day following receipt. Return of pumps or other materials to us or the authorized distributor must be agreed beforehand with the responsible personnel.

1.3 - PROPER USE OF THE PUMP

• The pump should be used only for the purpose for which it has been expressly designed, namely the dosing of liquid additives. Any different use is to be considered improper and therefore dangerous. The pump should not therefore be used for applications that were not allowed for in its design. In case of doubt, please contact our offices for further information about the characteristics of the pump and its proper use.
  The manufactures cannot be held responsible for damage deriving from improper, erroneous or unreasonable use of the pump.

1.4 - RISKS

• After unpacking the pump, make sure it is completely sound. In case of doubt, do not use the pump and contact qualified personnel. The packing materials (especially bags made of plastics, polystyrene, etc.) should be kept out of the reach of children: they constitute potential sources of danger.
• Before you connect the pump, make sure that the voltage ratings, etc., correspond to your particular power supply. You will find these values on the rating plate attached to the pump.
• The electrical installation to which the pump is connected must comply with the standards and good practice rule in force in the country under consideration.
• Use of electrical equipment always implies observance of some basic rules: In particular:

1 - do not touch the equipment with wet or damp hands or feet;

2 - do not operate the pump with bare feet (Example: swimming pool equipment);

3 - do not leave the equipment exposed to the action of the atmospheric agents;

4 - do not allow the pump to be used by children or unskilled individuals without supervision;

- In case of breakdown or improper functioning of the pump, switch off, but do not touch. Contact our technical assistance for any necessary repairs and insist on the use of original spares. Failure to respect this condition could render the pump unsafe for use.

- When you decide to make no further use of an installed pump, make sure to disconnect it from the power supply.

Before carrying out any service on the item, check:

1. Disconnect the pins from the mains or by means of a two poles switch with 3 mm minimum distance between the contacts. (Fig. 4).
2. Relieve all the pressure from the pump head and injection tube.
3. Drain or flush all dosing liquid from the pump head. This operation can also be done with the pump disconnected from the plant by turning the pump upside-down for 15 to 30 seconds and without connecting the tubing to the nipples: if this operation is not possible, dismount and remount the pump head using the four mounting screws.

In event of possible losses in the hydraulic system of the pump (breakage of the "0" ring gasket, the valves or the hoses) the pump should immediately be brought to a stop, emptying and depressurizing the delivery hose while taking all due safety precautions (gloves, goggles, overalls, etc.).

1.5 - TOXIC AND/OR DANGEROUS LIQUID DOSAGE

To avoid risk from contact with the hazardous liquids or toxic fumes, always adhere to the notes in this instruction manual:

• Follow the instructions of the dosing liquid manufacturer.
• Check the hydraulic part of the pump and use it only if it is in perfect condition.
• Use only the correct materials for the tubing, valves and seals to suit the liquid to be dosed; where possible shield the tubing with PVC conduit.
• Before disconnecting the metering pump, make sure to flush out and neutralize the pump head with the proper reagent liquid.

1.6 - ASSEMBLING AND DISMANTLING THE PUMP

1.6.1 - ASSEMBLY

All metering pumps are normally supplied fully assembled. For greater clarity, please consult the exploded view of the pump appended at the end of the manual, which shows all the pump details and a complete overview of all the pump components. These drawings are in any case quite indispensable whenever defective parts have to be re-ordered. For the same purpose, the appendix also contains other drawings showing the hydraulic parts (pump head and valves).

1.6.2 - DISMANTLEMENT

Proceed as follows before you dismantle the pump or before performing any other operation on it:

1. Disconnect the pins from the mains or by means of a two poles switch with 3 mm minimum distance between the contacts. (Fig. 4).
2. Relieve all the pressure from the pump head and injection tube.
3. Drain or flush all dosing liquid from the pump head. This operation can also be done with the pump disconnected from the plant by turning the pump upside-down for 15 to 30 seconds and without connecting the tubing to the nipples: if this operation is not possible, dismount and remount the pump head using the four mounting screws. (Fig. 11).

This operation calls for special attention, and you should therefore consult the drawings in Appendix and Chapter 1.4 "RISKS" before you commence work.

OVERALL DIMENSIONS (Fig. 1)

2.0 - EXACTUS SERIES METERING PUMPS

2.1 - OPERATION

The metering pump is activated by a teflon® diaphragm mounted on a piston of an electromagnet.

When the piston of the electromagnet is attracted, a pressure is produced in the pump body with an expulsion of liquid from the discharge valve. Once the electric impulse is finished a spring brings the piston back to the initial position, with a recall of liquid through the suction valve.

The operation is simple the pump does not need lubrication, therefore maintenance is reduced almost to zero. The materials used for the construction of the pump make it particularly suitable for aggressive liquids.

The metering pump has been designed to feed liquids with capacities from 0 to 20 l/h and pressures from 0 to 10 bar (depending on the model selected).

Fig. 2

The diagrams of fig. 3 indicate max metering pump flow variation in relation to the working pressure in the plant; the diagrams also include injection valve losses. I.V.P.

Due to production requirements the technical characteristics of our equipment at maximum ratings can vary with a tolerance of 5% which must be taken into account when choosing the type of pump.

a. - Install the pump in a dry place and well away from sources of heat and, in any case, at environmental temperatures not exceeding 40^ C. The minimum operating temperature depends on the liquid to be pumped, bearing in mind that it must always remain in a liquid state.
b. - Carefully observe the regulations in force in the various countries as regards electrical installations (Fig.4). When the supply cable is devoid of a plug, the equipment should be connected to the supply mains by means of a single-pole circuit breaker having a minimum distance of 3 mm between the contacts. Before accessing any of the electrical parts, make sure that all the supply circuits are open.

Fig. 4

c.- Locate the pump as shown in fig. 5 bearing in mind that it may be installed either below or above the level of the liquid to be dosed, though the level difference should not exceed 2 meters. When the process plant in which the pump is installed is operating at atmospheric pressure (no back pressure) and the chemical tank is situated above the plant (Fig. 6), the condition of the injection valve should be checked at regular intervals, because excessive wear and tear could cause additive to drip into the plant even when the pump is shut down. If the problem persist, install a properly calibrate counter-pressure valve (C) between injection point and the valve. In the case of liquids that generate aggressive vapours, do not install the pump above the storage tank unless the latter is hermetically sealed.

Fig. 7

e.- Remove the protection caps from the two nipples, slide the hoses over the connectors, pushing them right home, and then fix them with appropriate tube nuts. (Fig. 7).

Fig. 8

Whenever the pump is dismantled from the pipework, you will be well advised to replace the caps on the connectors to avoid residual liquid being spilled. Before attaching the delivery hose to the plant, prime the metering pump by going through the sequence shown in Fig. 8. Before finalizing the installation of the discharge hose, make sure that the pump strokes will not cause it to move and bump into rigid bodies. In case of priming difficulties, use a normal syringe to suck liquid from the discharge nipple while the pump is in operation, continuing until you actually see the liquid rise in the syringe. Use a short length of suction hose to connect the syringe to the discharge nipple. In case of a pump equipped with an air bleed valve, unscrew the air relief valve B up to all the air in the pump head will be out.

f. - Try to keep both the suction and discharge hose as straight as possible, avoiding all unnecessary bends.
g. - Select the most appropriate injection point on a pipe of the plant to be treated and there fit a 3/8" female steel gas thread connector (similar to BSPm). This connector is not supplied with the pump. Screw the injection valve to the gas connector, inserting a gasket as shown in Fig. 9. Then connect the discharge hose to the conical connector on the injection valve and fix it with the supplied tube nut G. The injection valve also acts as no return valve by means of a cylinder sleeve (elastomer, standard supplied in Viton®).

N.B. The sleeve D must not be removed.

1. Periodically check the chemical tank level to avoid the pump operating without liquid. This would not damage the pump, but may damage the process plant due to lack of chemicals.
2. Check the pump operating condition at least every 6 months, pump head position, screws, bolts and seals; check more frequently where aggressive chemicals are pumped, especially:
3. pulse and power L.E.D.;
4. the additive concentration in the pipework; a reduction of this concentration could be caused by the wearing of the valves, in which case they need to be replaced (Fig. 11) or by the clogging of the filter which then has to be cleaned as in point 3 here below.

Fig. 11

1. The Company suggests periodically cleaning off the hydraulic parts (valves and filter). We cannot say how often this cleaning should be done as it depends on the type of application, we also cannot suggest what cleaning agent to use as this will depend on the additive used.

Operating suggestions when dosing sodium hypochlorite (most frequent case):

a - disconnect the pins from the mains or by means of a onnipolar switch with 3 mm minimum distance between the contact.

b- disconnect discharge hose from pipework;

c - remove the suction hose (with filter) from the tank and dip it into clean water;

d- switch on the metering pump and let it operate with water for 5 to 10 minutes;

e - switch OFF the pump, dip the filter into a hydrochloric acid solution and wait until the acid finishes cleaning;

f- switch ON the pump again and operate it with hydrochloric acid for 5 minutes in a closed-circuit, with suction and discharge hose dipped into the same tank;

g- repeat the operation with water;

h- re-connect the metering pump to the pipework.

5.0 - HOW TO OPERATE WHEN DOSING SULPHURIC ACID (MAX 50%)

In this case it is essential to bear in mind the following:

1. replace PVC crystal suction hose with polyethilene discharge hose;

2. empty any residual water from the pump head beforehand.

Warning: if the water mixes with sulphuric acidit can produce a large quantity of gas with consequent overheating of the area causing damage to valves and pump head.

This operation can also be done with the pump disconnected from the plant by turning the pump upside-down for 15 to 30 seconds and without connecting the hose to the nipples; if impossible, dismount and remount the pump head (Fig. 11) using the four mounting screws.

D. By pressing buttons 3 and 10, you can select the mA input value corresponding to minimum pump output required. Confirm with enter 11. To finish the programming procedure and modify the maximum output value, press button 14 which will automatically change to mode Set 2.

- "Set 2" Mode

Mode Set 2 selects the mA input value/max. dosing pump flow and pulse/frequency.

A. Press button 14 Set 2 LED ON, the display will show the frequency previously set.
B. Press buttons 3 and 10 to set the desired imp/frequency at the maximum pump output required.
C. Press button 5 "mA/pulse", the display will show the value previously set.
D. Pressing 3 and 10 select the mA input value at the maximum pump output required.
E. Press button 11 to enter. The pump will automatically return to “METER” mode and is operational according to the selected functioning mode; two modes are available: direct/reverse.

- Direct Functioning Mode

During production the pumps are programmed for a 4-20 mA direct functioning curve. The pump will start every time the mA signal goes above 4 mA increasing the pulse frequency (and consequently the flow) proportionally to the mA input signal up to maximum imp/min frequency available. E.G. Set 1 minimum signal 4 mA, minimum output. Set 2 maximum signal 20 mA, maximum output.

- Reverse Functioning Mode

Reverse functioning is when the mA signal increases and pump output proportionally decreases. Select the maximum mA signal required with mode Set 1 (in relation to the min. output).

E.G. Set 1 maximum signal 20 mA, minimum output.

Set 2 minimum signal 4 mA, maximum output.

WARNING: Reverse functioning can only be selected when mode Set 1 is always higher than the mA signal.

Example n° 1: PUMP MODEL EXACTUS-CC, 10 L/H, 5 BAR, SIGNAL 4-20 mA.

Signal 4 mA = 0 l/h (0% pump flow rate)

Signal 12 mA = 5 l/h (50% pump flow rate)

Signal 20 mA = 10 l/h (100% pump flow rate)

Example n° 2: SAME MODEL, BUT WITH INVERSE SIGNAL: 20 - 4 mA

Signal 4 mA = 10 l/h (100% pump flow rate)

Signal 12 mA = 5 l/h (50% pump flow rate)

Signal 20 mA = 0 l/h (0% pump flow rate

9.6 - WATER METER MODE

1XN Mode

The pump is operated by an impulse produced by an external device (e.g. pulse emitting water meter) and it supplies a number of injections equal to the value visualized on the display "N" (set by the operator). In case during the dosing of the "N strokes" other pulses arrive, these are neglected.

Let's see how the pumps works with an example:

-Pump set in watermeter 1XN mode

- Set value on "20"

- At the time the water meter gives a pulse to the pump, it starts its 20 dosing injection strokes, if during this phase further shuts of the contact occur, these are neglected. Ended up the 20 injections, the pump is waiting for further pulses from the water meter to restart the dosing cycle.

1XN(M) Mode

The pump is operated by an impulse produced by an external device (e.g. pulse emitting water meter) and it supplies a number of injections equal to the value visualized on the display "N" (set by the operator). The injections are distributed with a variable frequency that depends by the time passed between a water meter pulse (produced by water meter) and the other.

Possible impulses (contacts) that may arrive to the pump while is already dosing are saved in the memory of the microcontroller, these will be delivered after the first batch is dosed.

Let's see how the pump works with an example:

The pump receives the first contact and returns a string "N" injections to the maximum frequency(e.g. 120 imps./min).

To the arrival of the second contact, the pump computes the time "T" spent by the arrival of the first one and it returns a string of "N" injections not more to the maximum frequency but to that it allows to uniformly distribute them in the time "T".

In case such time reduces, the pump keeps into consideration the injections "N1" which have not been delivered and add them to the "N" ones still not delivered. There are no problems if the time occurred between the contacts should length. If instead quick contacts occurs and it goes to condition N1 > 4 times N, the pump goes in alarm (on the display RL3 is visualized) but continues working and maintaining all the parameters set before by the operator but not dosing the strokes related to the last water meter pulses "N".

1:N Mode

The pump supplies an injection of chemical only when it has reached a number of pulses (contacts), equal to the value visualized on the display (set by the operator)

Let's see how it works with an example:

-Pump set with water meter 1:N

- Set value on "20"

- While the water meter supplies 20 pulses the pump discharge 1 stroke.

10.1 - MECHANICAL FAULTS

As the system is quite robust there are no apparent mechanical problems. Occasionally there might be a loss of liquid from the nipple because the tube nut has loosened, or more simply the discharge tubing-has broken.

Very rarely there may be losses caused by the breakage of the membrane, or by the membrane seals in which case they have to be replaced by disassembling the four screws of the pump head fig. 12), when remounting the pump head ensure that the screws are replaced properly, along with "O" ring.

After repair, the metering pump will need to be cleaned of additive residues which can damage the pump casing.

① - THE METERING PUMP GIVES PULSES BUT THE ADDITIVE IS NOT INJECTED

a. Dismount the suction and discharge valves, clean them and replace, see position (fig. 12). Should the valves be swollen, check valves material against our chemical resistance compatibility chart and fit correct valves. Standard valves are Viton. Upon request Silicon, EPDM (Dutral), Nitryl and valves, ball check valve, K valve can be supplied.

b. Check clogging of the filter.

ATTENTION: When removing the metering pump from the plant, be careful as there might be some residual additive in the discharge hose.

10.2 - ELECTRICAL FAULTS

① ALL LEDS OFF, THE PUMP DOES NOT PULSE

Check powersupply (socket, plug, power switch ON), if the pump doesn't work contact manufacturer Customer Service, Dealer or Distributor.

② GREEN LED (POWER) ON, RED LED (PULSE) OFF, THE PUMP DOES NOT PULSE

Press the START button. If the pump doesn't work contact manufacturer Customer Service, Dealer or Distributor

③ PUMP PULSES ARE NOT CONSTANT

Check that supply voltage is within +/- 10% of rated voltage.

④ THE DOSING PUMP GIVES ONLY ONE PULSE

Disconnect the equipment and contact manufacturer Customer Service, Dealer or Distributor.

11.0 - ELECTRODE HOLDERS

Three different types of electrode holders are available: monotubular for immersion, electrode cell, and in-line. It is essential to bear in mind that the distance between the injection point and the electrode must never be less than one metre. When this is not possible, an appropriate chemical mixer must be inserted between the injection point and the electrode.

12.0 - ELECTRODE CLEANING AND MAINTENANCE

The formation of deposits on the electrode will produce erroneous readings. The necessary cleaning action depends on the type of deposit under consideration. In the case of thin deposits, shake the electrode in the manner of a thermometer or use a spray of distilled water. Organic residues or particularly resistant deposits should

be removed by chemical means. Mechanical cleaning of the bulb should be resorted to only in extreme cases, but bear in mind that abrasion can lead to irreparable damage. If cleaning does not fully re-establish the efficacy of the electrode, it may be that the electrode has aged. Ageing will show itself in the for of either a measurement error or a slow response.
