MP Pumps 28398 FLOMAX Cast Iron 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 cast iron. This model is configured for close-coupled motor. It is sized for a 184C motor frame.
Always match by the MP Pumps part number 28398 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.
