500 GPH Cartridge Bilge Pump

Bilge pump cleaning and maintenance no longer call for complete disassembly. You can now leave the pump casing attached to both the boat and the hoses – assuming you own one of SPX Johnson Pump’s cartridge bilge pumps. Cartridge bilge pumps from SPX Johnson Pump can be removed for cleaning or replacement without the use of a single tool. Lift a tab on the top, give the cartridge a twist and pull it out; that’s all there is to it. The cartridge contains an all-in-one motor/impeller unit with no loose parts. The cartridge line is a further development of SPX Johnson Pump’s acclaimed bilge pumps, which have received highest ratings in many different independent tests over the years.

Water Cooled For Extended Service
The cartridge pumps are manufactured in the United States and the new line encompasses five compact pumps, each for a different capacity need. All of them use remarkably little electricity for the amount of water they pump. Their improved, more efficient motors also provide increased service life, thanks in part to an ingenious solution which circulates the discharge water around the motor for cooling.
