MP Pumps 21326 FLOMAX Bronze 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 150 GPM with total head up to 100 feet. Suction and discharge connections are 2 x 2 inch. Wetted construction is bronze. This model is configured for engine mount.
Always match by the MP Pumps part number 21326 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: 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.
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.
