Flexible Impeller Pump
 
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 (recommended for bilge pump application), the clutch will automatically disengage whenever the pump starts priming air, thereby preventing dry running and pump damage.
 
Applications:
Marine applications such as a bilge pump, deckwash pump, washdown, emptying holding tanks, engine cooling. It can also be used in Industrial applications such as liquid circulation and transfer, emptying tanks and sump drainage, and handling of solids in suspension. This flexible impeller pump provides an efficient solution to most raw water pumping needs. The primary advantage of a flexible impeller pump is its selfpriming 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 15 feet. 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. This Johnson flexible impeller pump combines the priming feature of positive displacement type pumps with the general transfer ability of centrifugals. It will pump either thin or viscous liquids and can handle more solids in suspension than other types of rotary pumps. It operates at low or high speeds can be mounted at any angle and pumps in either direction with equal efficiency.
