MP Pumps 36647 HHLF Cast Iron Self-Priming Centrifugal Pump
The HHLF (High Head Low Flow) series is a self-priming centrifugal pump line built for higher-pressure duty such as fire suppression, washdown, and auxiliary deck service, with several models carrying ABS Type Approval and 46 CFR compliance for marine fire-control use.
Wetted construction is cast iron.
Always match by the MP Pumps part number 36647 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.
