MP Pumps 21383 FLOMAX Bronze 3 x 3in 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 320 GPM with total head up to 145 feet. Suction and discharge connections are 3 x 3 inch. Wetted construction is bronze.
Always match by the MP Pumps part number 21383 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.

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.
