Frequently Asked Questions - 50973 WilTec
How do I prime the pump before first use?
Before starting, ensure the pump is fully submerged in water. For self-priming models, fill the pump housing with water until it overflows. Then connect the power and turn it on. Never run the pump dry, as this can damage the impeller and mechanical seal.
Can the pump operate automatically?
Yes, if your model is equipped with a float switch, the pump automatically switches on when the water level rises and switches off when it drops. Adjust the float switch to set the desired activation depth.
How often should I clean the pump filter?
Check the strainer or inlet filter before every use, and clean it whenever you notice a drop in flow. Regular cleaning prevents clogging and ensures efficient operation. Rinse the filter with clean water after each use in dirty conditions.
What is the maximum particle size the pump can handle?
This pump is designed for clean or slightly dirty water. The maximum particle size is typically around 5 mm. Larger debris such as stones or leaves may clog the pump and should be removed beforehand.
Can I use the pump for draining flooded rooms?
Yes, it is suitable for pumping out clear or lightly dirty water from basements or pools. Ensure the pump is placed on a flat surface and that the water level remains above the minimum required for operation.
What type of power connection is required?
The pump operates on a standard 230 V / 50 Hz electrical supply. It comes with a molded plug for direct connection. For safety, always connect it to a grounded outlet protected by a residual current device (RCD).
Why is the pump not delivering enough water?
Common causes include a blocked strainer, a kinked hose, or an excessive delivery head. Check that the pump is fully submerged and that the discharge hose is laid without sharp bends. Also verify that the total lift height does not exceed the pump's maximum head.
How should I store the pump during winter?
Drain all water from the pump, hoses, and connections to prevent freeze damage. Clean the pump thoroughly and store it in a dry, frost-free place. Store the float switch in a vertical position to avoid damage.
Are spare parts available for this pump?
Yes, WilTec offers spare parts such as impellers, seals, and float switches. Contact WilTec customer service or visit their website to order parts. Always quote the model number 50973 when ordering.
Can I pump saltwater with this pump?
No, this pump is not suitable for saltwater or corrosive liquids. The internal components would corrode and the pump would fail quickly. Use a marine-grade pump if you need to handle saltwater.
