DC Driven Flexible Impeller Pumps
Pumps suited for use in boats as bilge and deckwash pumps, fresh water pumps, refuelling pumps for oil and diesel. Can be combined with a vacuum switch for automatic operation. Capacities vary from max 14 l/min to 55 l/min, allowing the proper matching of the pump to the application. All motors are heavy duty to provide long service life even under heavy use.
F3B-19 F38B-19 F4B-19 F5B-19
Perfect for bilge pumping, deckwash, water circulation, oil and diesel refuelling at dockside service, etc.
F3B-19 Oil Change
Reversible rubber impeller pump with integrated quick reversing switch. Designed to remove old oil from the engine/fill new oil back into theengine.
F4B-11 Ultra Ballast
Designed to quickly fill or, when reversed, drain a ballast tank at a rate of more than 45 l/min (12 GPM). Capable of pumping fresh or sea water the pump's robust design can handle the rigors of continuous duty usage, is reversible, and has a built in thermal overload for added protection. Care not to run dry for extended periods of time will increase the pump longevity and ensure reliable performance for many years.
Note! Only for waterhandling.

Take good care of the cooling system – change to a new impeller every year!
The impeller is a very important security device. Its task is to pump the water through the cooling system of the engine. But remember that the impeller should be replaced every year. And always make sure you get a Johnson Pump Brand original impeller. Then you’ll know that it matches your pump exactly.
Remove the impeller with a slip joint plier or an Impuller.

Impeller removal has been made easier with the patented Sherwood Impeller Puller. Simply thread the puller into the threaded end of select Sherwood impellers and the bolt presses on the shaft, pushing the impeller out of the pump.
Sherwood's Impeller Puller is utilized on five different impeller sizes. Impeller puller 23631 is used on the 17000, 18000, 22000, and 27000 impellers. Impeller puller 24412 is used on the 27000 impeller.
