Johnson Engine Cooling, Raw Water Handling Pump, F35B-8, 3/8" NPT, 102456909
Self-priming Flexible Impeller Pumps are ideal for inboard engine cooling
systems.
Engine Cooling – Raw Water Handling
Flexible impeller pumps, F-series, provide an efficient solution to most raw
water pumping needs. The primary advantage of a flexible impeller pump is its
self-priming ability. As the vanes of the impeller are depressed and rebound,
they create their own vacuum drawing fluid into the pump. A dry pump can lift
water up to as much as 3 meters. Thus a flexible impeller pump being used for
engine cooling needs not be located below the water line or manually primed. An
added feature of flexible impeller pumps is that they can pass fairly large
solids without clogging or damaging the pump. This reduces the need for
filtering the incoming fluid.
For general raw or fresh water applications, the standard long lasting
neoprene rubber impeller is used.
A general feature of all flexible impeller pumps is that they cannot be
permitted to run dry for more than 30 seconds. Both the impeller and the seals
depend upon the water for lubrication and will soon burn out if run dry. Wearing
parts are easily replaceable, and service kits are available for all standard
models.
