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 (cooling water pumps for marine engines, bilge pumps, deck wash pumps,
fresh water pumps, fuel transfer pumps and other applications). 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.
