Frequently Asked Questions - ST2STWP-LT Lifan
How do I install the pump?
Place the pump on a firm, level surface. Connect the inlet to a 2-inch pipe (if needed) and ensure the outlet is directed away. For submersible use, fully submerge the pump and ensure no air is trapped.
Does it require priming?
Yes. Fill the pump body with water through the outlet port before starting. The pump is self-priming up to 6 meters vertically, but initial priming is essential to avoid dry running.
What type of water can I pump?
The pump is designed for clean water only. Do not use for sewage, flammable liquids, or liquids with large debris. Water temperature should not exceed 35°C.
Why is the pump not starting?
Check power supply and connection. Ensure thermal overload has not tripped – wait 15 minutes for it to reset. Verify that the pump is filled with water (no air lock) and that the pressure switch is functioning.
How do I handle air lock?
Air lock can occur after dry running. Turn off pump, loosen the outlet connection slightly to let air escape, then retighten and restart. For deep wells, install a foot valve to prevent backflow.
What maintenance is required?
Regularly check and clean the inlet strainer. Inspect seals for leaks and replace if worn. Lubricate bearings annually with water-resistant grease. Store pump in a dry, frost-free location.
Can I use an extension cord?
Yes, but use a heavy-duty cord rated for at least 15A and keep length under 30 meters to avoid voltage drop. Always keep connections dry.
What is the maximum operating depth?
When submerged, the maximum depth is 5 meters due to IPX8 rating. The pump can lift water from up to 35 meters vertical head (maximum suction lift 6 meters).
How do I winterize the pump?
Drain all water from the pump and hoses. Store indoors or in a heated area. Disconnect and dry the power cable. Apply a light oil to metal parts to prevent corrosion.
Is the pump repairable?
Yes. Common spare parts include impeller, mechanical seal, and capacitor. The pump is modular – you can replace these components with standard tools. Refer to the manual for detailed procedures.
