Frequently Asked Questions - 50312 WilTec
What type of water can I use with the WilTec 50312 pump?
The pump is designed for clean water only. Do not use with corrosive, flammable, or dirty liquids.
What is the maximum suction height?
The maximum suction height is 8 meters. Ensure the suction line is airtight for optimal performance.
How do I prime the pump before first use?
Fill the pump housing and suction pipe with water through the priming port. This ensures the pump can create suction and prevents dry running.
What does the thermal cut-off do?
The thermal cut-off automatically shuts off the pump if it overheats, preventing damage. Allow the pump to cool before restarting.
Can I use an extension cord with the pump?
Yes, but use a heavy-duty extension cord rated for the pump's power (800 W) and with a minimum cross-section of 1.5 mm². Keep it as short as possible.
How often should I clean the filter?
Clean the inlet filter after every use or when flow decreases. A clogged filter reduces performance and may cause overheating.
What is the maximum head pressure?
The pump can deliver water up to 35 meters vertically. The actual head depends on pipe friction and fittings.
Why is the pump not delivering water?
Check that the pump is primed, the suction line is not blocked, and the inlet filter is clean. Also verify that the voltage supply matches the rating.
Can the pump run dry?
No. Running dry damages the pump seals and impeller. Always ensure water is present before operation and install a dry-run protection device if needed.
How do I store the pump during winter?
Drain all water from the pump and pipes to prevent freezing damage. Store in a dry, frost-free location.
