Frequently Asked Questions - Feka VS DAB

The pump does not start, what to do?

First check that the motor is powered and the fuses are not blown. If the float switch is present, ensure it moves freely and the water level is sufficient. If the motor is three-phase, check the rotation direction. Refer to the paragraph IDENTIFICATION OF MALFUNCTIONS for more details.

The pump does not discharge water, what are the possible causes?

Common causes are: a clogged strainer or pipes, a worn or blocked impeller, a stuck check valve, or too low liquid level. Check each point and clean or replace defective parts. Also ensure that the head does not exceed the pump's capabilities.

How to adjust the float switch?

Lengthen or shorten the cable between the float and the fixed point (flange on the handle) to change the start (START) and stop (STOP) levels. Make sure the float can move freely. The minimum stop levels are 370 mm (models 550-750) or 400 mm (models 1000-1200) from the bottom.

What oil to use for the seal and how much?

Use about 170 g of oil type MARCOL 152 ESSO. To drain, disassemble the hydraulic part, remove the plug (64), tilt the pump to recover used oil. Check if it contains water or abrasive particles; if so, replace the mechanical seal. Recycle used oil.

How to check the rotation direction on a three-phase version?

Place the pump on a flat surface, start it then stop immediately. Observe the kickback: the direction is correct if the red cap turns in the indicated direction (clockwise). If the pump is already installed, compare the water flow after swapping two phases; the correct direction corresponds to the lowest flow and power consumption.

The pump stops by itself, why?

This may be due to thermal overload: the liquid is too dense or too hot, or the pump is partially blocked by impurities. The amperometric thermal protection stops the motor automatically. Wait for cooling; if the problem persists, clean the pump and check the liquid temperature.

Can I use the pump in a swimming pool with bathers?

No, these pumps must not be used in swimming pools, ponds, or basins where people are present in the water. They are not designed for pumping hydrocarbons (gasoline, diesel, etc.). Use them only for applications compliant with standards.

How to install the DSD2 lifting device?

Fix the base foot at the bottom of the tank, insert the two 3/4'' pipes (not supplied) connecting the lower flange and the upper guide flange. Attach the base flange to the pump, then assemble the slide to the discharge outlet. Place the assembly back on the foot. This device facilitates maintenance without disassembling the pipe.

What to do in case of freezing?

If the pump remains inactive at a temperature below 0°C, make sure there is no residual water inside, as ice could crack components. Completely drain the pump before prolonged storage during freezing periods.

How to clean the suction strainer?

Before positioning the pump, check that the strainer is not clogged with mud or sediments. After use, rinse the installation with a strong water jet to avoid deposits. If the strainer is obstructed, disassemble it and clean it thoroughly.

3. WARNINGS

The pump is provided with a carrying handle which may also be used to lower it into wells or deep holes with a rope or cable.
If the power cable is damaged in any way it must be replaced and not repaired (use cable with minimum length 32.8 ft (10 m) for the portable version, with a plug for the SINGLE-PHASE version and with stripped wire for the THREE-PHASE version). This must be connected by skilled personnel, in possession of the qualifications required by the regulations in force.
The pump must never be allowed to run dry.

4. INSTALLAZIONE

4.1 If the bottom of the well or borehole in which the pump is to operate is particularly dirty, it is advisable to provide a support for the pump to sit on so as to avoid clogging of the intake grid (Fig.1).
4.2 Before putting the pump in position, ensure that the strainer is not totally or partially blocked by mud, sediment or similar substances.
4.3 It is advisable to use pipes with an internal diameter at least equal to that of the delivery mouth, to avoid falls in pump performance and the possibility of clogging. In cases where the delivery pipe has long horizontal stretches, it is advisable for this pipe to have a larger diameter than that of the delivery mouth.

Totally immerse the pump in the water.

4.4 On the version provided with a float switch, ensure that the float can move freely (SEE THE PARAGRAPH ON ADJUSTING THE FLOAT SWITCH). Ensure that the minimum dimensions of the borehole are as in Fig.1. The dimensions of the borehole must also be calculated with relation to the quantity of water arriving and to the pump flow rate so as not to subject the motor to excessive starting operations.
4.5 When the pump is to be in a fixed installation, with a float, a check valve must always be fitted in the delivery pipe. This is also advisable on pumps with manual operation.
4.6 Connect the delivery pipe or hose directly to the pump mouth. If the pump is used in fixed installations it is advisable to connect it to the pipe with a coupling so as to facilitate disassembly and reinstallation. If a hose is used, fit a threaded hosetail on the pump mouth. Wrap the thread with suitable material to ensure an effective seal (teflon tape or similar).

For fixed installations we advise the use of the lifting device DSD2 (available on request - Fig.2) to facilitate pump maintenance operations. When fitted between the pump delivery aperture and the pipe, it avoids having to remove the delivery pipe during maintenance jobs. The DSD2 device is composed of 8 parts:

The foot is positioned on the bottom of the tank and fixed with expansion screws of suitable dimensions. The pipe guide bracket must be positioned at the top of well or borehole and inserted in the end of two 3/4 pipes (not supplied), which act as a slide. The two pipes connect the bracket to the foot. Position the base bracket in contact with the pump suction strainer near the delivery aperture, secure everything to the strainer cover with the screws provided to lock the strainer cover.

Remove the top screw from the flange on the delivery side ( I ). Assemble the anti-rotation bracket ( G ) . Replace the screw ( I )

Extract the slide from the coupling foot and connect it to the delivery port of the pump.

Using the screw F and the nut H, fix the slide to the pump as indicated in the figure.

Reposition the slide/pump assembly on the foot (Fig.2).

5. ELECTRIC CONNECTION

Caution: always follow the safety regulations!

5.1 Single-phase motors are provided with built-in thermal overload protection and may be connected directly to the mains. N.B. If the motor is overloaded it stops automatically. Once it has cooled down it starts again automatically without any need for manual intervention.
5.2 Three-phase pumps must be protected with motor protectors suitably calibrated according to the values on the data plate of the pump to be installed. The plug on the pump must be connected to an EEC socket complete with isolating switch and fuses.
5.3 Do not damage or cut the power cable. If this should occur accidentally, have it repaired or replaced by skilled and qualified personnel.

6. CHECKING THE DIRECTION OF ROTATION (for three-phase motors)

3

The direction of rotation must be checked each time a new installation is made.

Proceed as follows (Fig.3):

1. Place the pump on a flat surface.
2. Start the pump and stop it immediately.
3. Carefully observe the kick-back on starting, looking at the pump from the motor side. The direction of rotation is correct, that is clockwise, if the protection cap moves as in the drawing (anti-clockwise).

If it is not possible to check as described above because the pump is already installed, check as follows:

1. Start the pump and observe the water flow rate.
2. Stop the pump, switch off the power and invert two phases on the supply line.
3. Restart the pump and check the water flow rate again.
4. Stop the pump.

The correct direction of rotation will be the one in which the flow rate and electric absorption are LOWER!

7. STARTING UP

Models with a float switch start up automatically when the water level rises; models without a float are started by means of a switch located upstream from the socket (not supplied).

L

usting the float switch

gthening or shortening the cable between the float and the fixed point (slot provided in the handle - Fig.4) i s the START or STOP level of the pump. Be sure that the float can move freely.

FEKA VS-VX 550-750 Minimum stopping level 14.57'' (370mm) from the bottom.

FEKA VS-VX 1000-1200 Minimum stopping level 15.75^ (400mm) from the bottom.

8. PRECAUTIONS

8.1 The intake strainer must always be in place during pump operation.
8.2 The pump should not be started more than 20 times in one hour so as not to subject the motor to excessive thermal shock.
8.3 DANGER OF FROST: When the pump remains inactive for a long time at temperatures of less than 32^ (0^) , it is necessary to ensure that there is no water residue which could freeze and cause cracking of the pump components.
8.4 If the pump has been used with substances which tend to form a deposit, rinse it after use with a powerful jet of water so as to avoid the formation of deposits or scale which would tend to reduce the yield of the pump.

Connect pumps that are delivered without cable and/or plugs to an external mains switch with a minimum contact gap of 0.12" (3 mm) in all poles.

9. MAINTENANCE AND CLEANING

In normal operation, the pump does not require any specific maintenance, thanks to its mechanical seal lubricated in an oil chamber and to its sealed-for-life bearings. The electropump must not be dismantled unless by skilled personnel in possession of the qualifications required by the regulations in force. In any case, all repairs and maintenance jobs must be carried out only after having disconnected the pump from the power mains.

During disassembly, pay attention to any sharp parts which could cause injury.

Checking and changing the sealing oil

To perform this operation, slacken the six screws (45) so as to be able to remove the strainer cover, the strainer and the pump body (1). Retain the O-ring (28) and the nuts (51). Using a suitable spanner, unscrew the impeller retaining nut (18), holding the impeller (4) still with your hand. Retain the key (17) and the sand guard (15). Now overturn the pump with the hydraulic part facing upwards, unscrew and remove the drainage cap (64).

Tilt the pump so as to let the oil flow out of the drainage hole (64) and catch it in a container. Analyse the oil: if you find any particles of water or abrasive materials (for example, sand) it is advisable to check the condition of the mechanical seal (16) and to have it changed if necessary (at a specialized centre). In this case change the oil too, with about 6oz 170 gr of oil type MARCOL 152ESSO.

Top up the oil level inside the sealing oil chamber using a special funnel inserted in the hole in the cap (64). Screw the drainage cap (64) back on and perform the disassembly operations in inverse order to reassemble the pump after having spread a suitable amount of teflon grease in the seat of the sand guard (15).

OLD OIL MUST BE DISPOSED OF AS REQUIRED BY THE REGULATIONS IN FORCE.
