Frequently Asked Questions - 47808 Draper
How do I prime the pump?
Fill the pump casing with water through the outlet port before starting. This ensures the impeller is submerged and prevents dry running.
Can the pump handle dirty water?
This pump is designed for clean water only. Do not use with water containing solids larger than 1 mm, as they may clog the impeller or damage the seals.
What is the maximum suction lift?
The maximum suction lift is 8 meters. For optimal performance, keep the suction line as short and straight as possible.
How do I clean the pump?
Disconnect the pump from the power supply. Remove the strainer at the inlet and rinse it with clean water. Use a soft brush to clean the housing if necessary.
Why is the pump not starting?
Check that the power supply is connected and the thermal overload has not tripped. If tripped, allow the pump to cool for 15 minutes and press the reset button.
What type of oil does the pump use?
This pump is oil-free and does not require any oil. The bearings are permanently sealed and lubricated.
Can the pump run dry?
No, never run the pump dry. Dry running can damage the mechanical seal and cause the pump to overheat. Always ensure the pump is primed before operation.
How do I replace the mechanical seal?
Seal replacement requires disassembling the pump. Remove the volute and impeller, then extract the old seal. Install a new mechanical seal and reassemble. Refer to the service manual for detailed steps.
Is the pump suitable for salt water?
No, this pump is not designed for salt water or corrosive fluids. The cast iron housing and stainless steel parts may still corrode in saline environments. Use a specifically designed pump for such applications.
What is the warranty period?
Draper offers a 2-year warranty from the date of purchase. The warranty covers manufacturing defects but not wear and tear or damage from misuse.
