Introduction
Thank you for choosing to purchase this quality product. To minimise the risk of injury, we ask you to always take some basic safety precautions when using this product. Please read this operating manual carefully and make sure that you understand it. Keep these operation instructions in a safe place.
Safety instructions
The symbols and the sentences including the words “danger” or “warning” wish to call your attention to the dangers and possible consequences of non- compliance with the safety instructions.
| Symbol | Danger: Non-compliance with the safety instructions might … |
|---|---|
| … lead to an electric shock. | |
| … cause severe damages caused to your health. | |
| … damage the pump. |
General remarks
- Make sure that the product has been installed correctly to work at its best.
- All materials have undergone a meticulous inspection. Installing correctly the pump contributes to the protection of the pump against damages and overcharge. Any non-compliance with the instructions can cause damages to the pump.
- Always use a non-return valve.
- The pump must not be immerged into water. The water is sucked in via a hose.
- Prime the pump and suction line with water before using it; otherwise, it will run the risk of running dry.
- Check if there is a water column (prime the pump with water before use until the water column is present to 100 %).
Assembly
- The pump must be set up on a level and firm surface.
- The end of the suction line should be immerged at least 30 cm at the lowest point of the water.
- The suction line must have a slope in the water-sampling direction; that must be done so that the line has no bends that could provoke a water accumulation.
- Never hang up the pump by an electric cable or line.
- Before use, make sure that there is a continuous water column.
- It is advisable that you install a tube with a larger diameter than that of the outlet to reduce the friction loss as much as possible.
- Install a non-return valve to the entry of the pump to prevent that the line is emptied at every stop of the pump.
- Avoid that tube lines are bent or twisted and make sure that the connection to the outlet is correct. In both cases, the flow at the outlet is reduced if the connection be bad.
Checks before start
- Make sure that the existing mains voltage and frequency match the specifications on the nameplate of the device.
- Make sure that the condenser corresponds to the requirement of the pump (one phase).
- Make sure that the suction through the hose works without any problem. If the suction device of the pump should not work properly, the hydraulic elements of the pump could be damaged.
- In case the suction line is bent/curved, a non-return valve with a sieve should be installed to the end of the suction tube/line.
- All connections of the suction line must be installed correctly and tightened completely.
- Do not use anti-vibration hoses, that might impair the flow.
- Before start, check the direction of rotation.
- Never let the pump run dry. The pump and suction line should always be filled with water
Operating the pump
- Set up the pump on a level and solid surface.
- Place the pump at a horizontal position to help the bearing to work properly and to fix the pump the surface.
- Install the suction line so that it is ready for use. The suction hose should not be narrower than the suction connection.
- Connect to mains.
- Fill in the pump with water at the pressure port.
- During the suction process, the shut-off devices (valves, spray nozzles, etc.) in the pressure line must be completely open so that the air in the suction line can escape freely.
- Depending on the suction height and air quantity in the suction line, the first suction process can take some time. With longer suction periods of sucking in, new water should be refilled.
- If the pump is removed after its use, do not forget that it must be refilled with water before you operate the pump again and before restarting and connecting it again.
In case there is a water accumulation or you hear a rattling noise, the pump cannot build up the required pressure to switch off automatically. In such case, it must be assumed that the system has not been purged or that there is a leaking spot in the suction zone. A possible leakage can be detected as follows:
- Fix one end of the suction hose to a water tap.
- Now open the water tap and place the other end of the suction hose into another recipient filled with water.
- Should you detect a spot where water and air bubbles come out, this is the leaking spot. In such case, the device cannot work properly
Attention! The pump is equipped with an overheat control, but it has no safety device that switches off the pump automatically when it runs dry.
Electric connections
The one-phase motor has been installed with a thermo-protection. With a three- phase pump, this protection should be realised by the user

Maintenance
Our pumps do not require any special maintenance; however, we ask you to follow the following advice:
Attention!
- Before every maintenance, the pump must be switched off; to do so, disconnect the pump from the power supply.
- Before a longer period of non-operation or winter storage, the pump must be rinsed thoroughly with water, emptied completely, and stored at a dry location.
- In case of frost danger, the pump must be completely emptied.
- After long non-operation periods, check if a proper turning of the rotor takes place by shortly switching the device on and off.

Troubleshooting
If the pump stops or breaks off water suction, check the following:
- Is there water in the water source?
- Is the non-return valve completely submerged in the water?
- Is the suction unit obstructed by dirt or leaking?
- Has the suction depth been exceeded?
The engine does not run
| Cause | Solution |
|---|---|
| Lack of voltage | Check voltage. |
| Pump impeller blocked – thermo-controller has switched pump off | Dismantle and |
clean pump.
Pump does not suck in
| Cause | Solution |
|---|---|
| The suction valve not in the pumped medium | Install a suction valve inside the |
water.
Pump room without water| Fill in the pump medium in the suction nozzle.
Air in suction line| Check if suction line is well sealed.
Suction valve leaking| Clean suction valve.
The suction strainer (suction valve) blocked| Clean suction basket.
Max. suction lift exceeded| Check the suction lift.
Insufficient flow rate
| Cause | Solution |
|---|---|
| Suction lift too high | Check the suction lift. |
| Suction strainer dirty | Clean suction basket. |
| Water level drops rapidly | Lower suction valve. |
| Pump capacity reduced because of harmful sub-stances | Clean the pump and |
replace worn parts.
Thermo-switch switches off the pump
| Cause | Solution |
|---|---|
| Engine overloaded – excessive friction due to foreign particles | Dismantle and |
clean the pump, prevent the sucking-in of foreign matter (Filter).
