MP Pumps 28399 FLOMAX Stainless Steel 2 x 2in Self-Priming Centrifugal Pump
The FLOMAX line is a self-priming centrifugal pump series built for general industrial, agricultural, and marine transfer duty. Once primed, an internal flapper check valve holds a column of liquid in the suction line so the pump can re-prime on the next start without manual assistance.
This unit is rated up to 140 GPM. Suction and discharge connections are 2 x 2 inch. Wetted construction is stainless steel. This model is configured for pedestal.
Always match by the MP Pumps part number 28399 stamped on the unit or listed on your equipment parts diagram, since pump configurations vary by mount type, material, and port size even within the same series.

Frequently Asked Questions
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.
Q: Does this come with a motor or engine?
Availability varies by listing. PumPak versions are a bare, run-tested pump end for coupling to your own driver; complete units include the motor or engine as noted in the title.
Q: How do I know this is the right pump for my equipment?
Match it by the MP Pumps part number stamped on the unit or listed on your equipment parts diagram. Send us a picture of your pump plate and we will confirm fitment.
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.
