SPX FLOW Johnson Pump Marine Impeller 09-806B-1for pump F35 
MC97/EPDM 40 mm 9.5 mm/ Flat 19 mm
 
This impeller is an original Johnson Pump SPX Flow Sweden product. Unlike cheap Asian counterparts, the original SPX FLOW impeller from Johnson Pump: a correct cooling current, a significantly longer service life, excellent self-priming capacity, sufficient cooling immediately at start
Thus, due to their construction, pumps with flexible impeller can promote relatively large solids. When the flexible impeller shovels come into contact with the cam again, they bend and the liquid comes out of the pump in an even flow. Liquids can be pumped upside down.
Correct wheel dimensions thanks to the unique MC97 rubber compound in SPX Flow wheels ensure maximum service life, especially when the end user does not start the engine regularly: constant pressure supply over time, minimal fatigue failure, minimal swelling, direct cooling at start
Johnson Heavy Duty Bronze Universal Pump Impellers are raw water resistant and compact. These pumps have been developed for a variety of marine applications and have proven themselves in terms of quality and reliability. With excellent self-priming capacity, these pumps are ideal as cooling water pumps for marine engines, bilge pumps, deck wash pumps, fresh water pumps, fuel pumps (nitrile impeller only) and other applications
For general raw or fresh water applications, the standard durable neoprene rubber impeller is used. A general feature of all pumps with a flexible impeller is that they must not run dry for more than 30 seconds. Both the impeller and the seals are dependent on water for lubrication and will soon fail when running dry
Suction height up to 3 metres. Wheel operating temperature minimum: 5 °C / 41 °C, maximum: 55 °C / 131 °F
The main advantage of a flexible impeller pump is its self-absorbency. When the blades of the impeller are pressed down and bounced back, they create their own vacuum that sucks liquid into the pump. A dry Johnson pump can lift water up to 3 metres. Thus, a flexible impeller pump, which is used for engine cooling, does not need to be arranged under the water line or manually sucked in.
An additional feature of pumps with a flexible impeller is that they can pass through relatively large solids without clogging or damaging the pump. This reduces the filter requirement of the incoming liquid
Johnson Pump Marines products provide continuous reliability even in the most difficult conditions and are designed to maximise efficiency while minimising energy consumption and maintaining quiet operation. With their help, the long-term maintenance of ships can be maintained at the highest level and in addition, SPX FLOW technology contributes to the comfort and safety of suiters, crew and passengers.
Flexible wheels – functional principle vacuum is created when aligning the flexible impeller blades from the cam, suction of liquid into the pump. A rotating impeller promotes liquid from the inlet to the outlet.
