Frequently Asked Questions - 50374 WilTec
Can the WilTec 50374 pump dirty water?
Yes, it is designed for rainwater and lightly contaminated water. The maximum particle size is about 5 mm, so it can handle leaves or sand without damaging the impeller.
How high can the pump push water?
The WilTec 50374 achieves a maximum delivery head of 25 metres and a maximum flow rate of 6000 litres per hour. The flow decreases as the pumping height increases.
Can the pump run dry?
No, running dry damages the mechanical seal and impeller. The integrated thermal protection switches the motor off if it overheats, but the pump should be switched off and submerged again quickly.
How do I clean the pump after use?
Rinse it with clean freshwater and remove any dirt from the suction screen. Do not use aggressive cleaning agents or solvents, as they may attack the plastic housing.
Why is the pump not priming or losing suction?
Check that the suction screen is not blocked, the hose is not kinked, and the pump body is fully submerged. Air leaks in the connection thread will also stop it from priming.
How long can the pump run continuously?
The motor is designed for intermittent use; for continuous operation, a duty cycle of about 30 minutes followed by a cooling break is recommended. The thermal switch protects the motor from permanent damage.
Is the pump suitable for swimming pool drainage?
Yes, for clear pool water it is suitable. For heavily chlorinated or salty water, rinse the pump thoroughly after use to prevent corrosion and deposits.
What does the float switch do?
The automatic float switch turns the pump on when the water level rises and off when the water level drops, enabling dry-running protection and unattended operation.
How should the pump be stored in winter?
Drain all residual water and store the pump in a frost-free, dry room. A completely dry pump will not be damaged by freezing.
Where can I find spare parts for the WilTec 50374?
Spare parts such as the impeller, shaft seal, power cable and float switch are available from WilTec or authorised dealers. Use only genuine parts to maintain safety and performance.
