The FMX series extends the FLOMAX self-priming centrifugal pump line to higher flow and head duty, for general industrial, agricultural, and marine transfer applications. 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 FMX 150 model is 316 stainless steel construction with 1-1/2 x 1-1/2 inch ports, sized for a 56C motor frame with a 6.0 inch impeller. It is rated to move over 100 GPM at up to 110 feet of head, with a standard carbon/ceramic/Viton mechanical seal.
Always match by the MP Pumps part number 51016 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.
