Frequently Asked Questions
Q: What does self-priming mean for this pump?
A self-priming pump can clear air from its own suction line on startup rather than needing the line pre-filled with liquid, using an internal check valve to hold prime between runs.
Q: Can this pump run dry?
No. Running a centrifugal pump dry for more than a few seconds can damage the mechanical seal and impeller. Shut the pump off if it loses prime and will not reprime on its own.
Q: Is this a genuine MP Pumps part?
Yes, this is a genuine MP Pumps unit, sold under MP Pumps part number 39640.
Q: What maintenance does this pump need?
Periodically check the mechanical seal for leaks, inspect the impeller for wear, and keep the suction line free of debris that could clog or damage the impeller.
