Question 1

What is the maximum suction depth of the DAB Jet 102 M pump?

Accepted Answer

No, this pump cannot effectively pump down to 12 meters deep. The DAB Jet 102 M pump is self-priming up to 9 meters maximum only, according to its technical specifications.

With a 12-meter well, you exceed the suction limit of this pump. Therefore, it would not be able to prime correctly or reach the bottom of the well under these conditions.

Solutions for a deeper well:

Submersible pump: Submerge the pump directly in the well. It then does not need to create a suction column and can operate at unlimited depths.
Elevation of the water point: If possible, raise the water level in the well (for example with a water recovery system) to bring it closer to the maximum suction of 9 meters.
More powerful pump: Opt for a multi-stage surface pump or a professional model capable of sucking at depths greater than 12 meters.

Consult the DAB supplier if you are considering deep well use for a suitable recommendation.

Question 2

Where is the priming hole of the DAB Jet 102 M pump and how do I prime it?

Accepted Answer

The priming hole of the DAB Jet 102 M pump is located on the body of the pump and is accessible by removing the filling cap.

Priming Procedure (Section 6.1)

Remove the filling cap located on the body of the pump
Fill with clean water through the designated hole until the pump is completely full
Carefully screw the cap back on once the operation is complete

This procedure is illustrated in Figure F of the manual.

Important: Running dry causes irreparable damage to the mechanical seal. If the pump has not been used for a long time, repeat this procedure before restarting it.

The DAB Jet 102 M pump is self-priming up to 9 meters of suction depth.

Question 4

Where are the fuses for the DAB Jet 132 M pump located?

Accepted Answer

The PDF of this manual does not specify the physical location of the fuses. However, the documentation clearly states that you must check the protective fuses and replace them if they are blown.

Here’s how to proceed:

First, unplug the pump - The manual specifies that all repair and maintenance work must be carried out after unplugging the device
Locate the terminal box - The electrical diagrams for this pump are found in the terminal box. This is generally where the fuses or circuit breaker are installed
Check the type of protection - Depending on your installation, you may have either circuit breakers with fuse holders (for fixed installations) or thermal amperometric protection (for single-phase motors)
Replace with identical fuses - Adhere to the amperage specified on the technical label of your pump

If you cannot find the fuses or are not comfortable with electrical work, contact a qualified electrician or DAB customer service.

Question 5

Why is my DAB Jet 132 M pump not working when the indicator light is green?

Accepted Answer

The PDF of this manual does not explicitly state the meaning of the green indicator light. However, if the controller shows green but the pump is not pushing water, here are the most common causes:

Checking the priming

Make sure the pump is filled with water. According to the manual, you should fill the pump with clean water through the filling hole provided on the pump body.
Air in the suction piping prevents priming. The manual states that air must be eliminated. Completely purge the suction line.
The pump can prime up to a maximum suction height of 9 meters - check that you are not exceeding this limit.

Checking motor operation

The green light may indicate that the motor is receiving electrical power, but this does not mean that the pump is pushing. Listen to see if the motor is running: if it makes no noise, check the electrical connections and fuses.
If the motor is running but no water is coming out, there may be an internal blockage (check valve stuck, obstructed passage).

Other checks

For three-phase installations, the direction of rotation must be clockwise (viewed from the fan side). If the direction is reversed, two conductors must be swapped, and the pump will not push.

Question 6

Where is the integrated non-return valve located in the DAB Jet 132 M pump?

Accepted Answer

The DAB Jet 132 M manual does not specify the exact location of the integrated non-return valve within the motor or pump body. This component is generally factory-installed in the suction pipe or at the inlet of the pump body, but is not directly accessible without complete disassembly.

However, the technical document mentions the foot valve located externally, at the bottom of the suction hose, which serves a similar purpose to prevent backflow. This valve is more accessible and can become clogged with debris.

Practical maintenance

External foot valve: clean it regularly if the pump has difficulty sucking water, even after priming (reduced flow, unusual noise)
Internal non-return valve: according to DAB, any internal maintenance should be entrusted to a professional, as access requires disassembly of the motor and risks damaging the mechanical seals
Check the sealing of all suction connections (absence of air) before suspecting a fault with the non-return valve

If the pump does not hold pressure after stopping (spontaneous drainage of the discharge hose) and the foot valve is clean, contact an authorized DAB repairer.

Question 7

The DAB Jet 132 M pump is not drawing water and is making noise - what should I do?

Accepted Answer

This problem usually occurs when the pump is not filled with water before starting. According to the technical documentation of the DAB Jet 132 M, incorrect operation without priming irreparably damages the mechanical seal.

Immediate Priming Procedure

Stop the pump immediately if it is currently running
Locate the filling cap on the body of the pump
Remove the cap and pour clean water directly into the filling opening until completely full
Replace the cap and ensure it is tightly secured
Restart the pump

In 9 out of 10 cases, filling the pump with water resolves the suction issue and the cavitation noise.

If the problem persists after priming

Check the tightness of the suction piping - An air leak at the foot valve or fittings will allow air in instead of water. Check the seals and tighten the connections.
Clean the foot valve - The valve may be clogged, preventing water from rising. If the suction piping is long, this blockage is common.
Reduce the suction height - The DAB Jet 132 M is designed for a maximum suction height of 9 meters. Beyond that, the pump cavitates (creates air bubbles) and makes noise.

Warning: Never let the pump run without water. This irreversibly damages the mechanical seal. Priming before each start is mandatory.

Question 8

Is the pressure of the DAB JET-MP pump adjustable?

Accepted Answer

No, the pressure of the DAB JET-MP pump is not adjustable. There is no button or dedicated control to adjust the operating pressure.

The pressure generated by this pump depends solely on its fixed technical characteristics:

Maximum manometric height: 40 meters (approximately 4 bars of pressure)
Maximum flow rate: 50 L/min
Type: self-priming centrifugal pump

The actual pressure varies depending on the discharge height and the load of the system (requested flow rate, length of piping, etc.). The higher the height, the more the pressure naturally decreases.

If you need a different pressure for your specific application, you may consider installing an external device such as a pressure switch or a pressure reducer on the discharge circuit.
