Johnson F4B-8 Heavy Duty Impeller Pump

Compact design, raw water resistant pumps at an attractive price. With excellent self-priming capability, these pumps are ideal for applications like engine cooling, bilge pumping, wash-down, refuelling, emergency and fire fighting.  Also ideally suited for shore for emptying septic tanks, flushing, cleaning and filling water tanks. Flexible impeller pumps provide an efficient solution to most raw water pumping needs. The pumps are self-priming and can pass fairly large solids without clogging or damaging the pumps. Designed for a number of applications on board.  With an electro-magnetic clutch you will have pumping power whenever needed, at a push of a button, without being at the pump. Combined with a vacuum switch from Johnson Pump (recommended for bilge pump application), the clutch will automatically disengage whenever the pump starts priming air, thereby preventing dry running and pump damage.

Automatically controlled pumps are available in sizes from 1in to 2.1/2in (20 L/min to 625 L/min), with clutches in 12 or 24 volts. Wearing parts are easily replaceable
