Product Overview

SEAFLO MARINE Seawater Circulation Pump

Designed for the constant demands of marine air conditioning systems up to 24,000Btu. The SEAFLO SFCPA1-G500-01 is a Magnetic Drive Seawater Circulation Pump. It easily replaces comparable competing brand’s pumps with similar fittings and mounting base. It is a completely submersible seal-less centrifugal magnetically driven pump, with no shaft seal, and a high-performance graphite bearing system.

The motor and motor cooling system are completely epoxy encapsulated, which allows the pump to run in open air for complete moisture protection or even fully submerged in liquid. The pump has run dry protection. 115V AC 50/60 HZ.

The motors are internally water cooled, using the water it circulates to keep it cool, making it continuous duty rated and able to handle the rigorous needs of air conditioning applications. Generating a maximum flow of 8.5 gallons per minute with a maximum head of 19 feet at 8.2 PSI. The inlet connection is a ¾” female pipe thread (FPT) and the outlet is ½” male pipe thread (MPT).
