The original SPX FLOW Johnson Pump 09-1027B-9 impeller kit is designed for the F5B type pump. With the help of spare parts and instructions, you can easily replace the impeller on your pump yourself. Replacing the impeller is recommended regularly once a year or if the pump's vacuum performance is impaired. For example, when suction takes more than 30 seconds <br> <br> All accessories included are not a cheap Asian copy. Material of the impeller is made of Nitrile for water with a lot of oil and diesel.. Specifications include outer diameter of 2.25" (57.1 mm), inner diameter: Splines, and width of 1.24" (31.5 mm)

Flexible impeller Johnson pumps provide an efficient solution to most raw and salted water pumping needs. The pumps are self-priming and can pass fairly large solids without clogging or damaging the pumps. Johnson engine cooling pumps are designed to the demands of the world’s leading marine motor manufacturers, not just because of our renowned pumps; but also because of SPX Flow’s advanced original impeller design and technology - the heart of an engine cooling pump
 
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 Johnson pump can lift water up to as much as 3 meters. Thus a flexible impeller pump being used for engine cooling does not need to 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 fail if run dry. Wear parts are easily replaceable, and service kit 09-45585 is available for F5B model.

It is also common to use a flexible impeller pump for this purpose if it is located on the cold side of the system (max. 55°C/ 131°F ). Other types of belt-driven centrifugal pumps may also be useful. The closed circuit normally transfers heat from the engine to the heat exchanger. The liquid is a water and anti-freeze mixture.
 
The required output of the cooling pump – raw water as well as fresh water handling – is related to:
• Engine size and type (gasoline or diesel)
• Type of cooling system (size of heat exchanger)
• Water cooled engine oil, reverse gear, exhaust system
 
FLEXIBLE IMPELLERS - OPERATING PRINCIPLE
• A vacuum is created as the flexible impeller vanes straighten upon leaving the cam,
drawing liquid into the pump
• The rotating impeller carries liquid from the inlet to the outlet port. As a consequence of
their design, flexible impeller pumps can pass fairly large solids.
• When the flexible impeller vanes regain contact with the cam, they bend and the liquid
is discharged from the pump in a uniform flow. Liquids can be pumped in the opposite
direction by reversing the rotation of the pump.
 
Johnson pumps with Heavy Duty range of multi-purpose bronze pumps are raw water resistant and have a compact design. These pumps are designed for a number of applications onboard and have gained a time-tested reputation for quality and reliability. With excellent self-priming capability, these pumps are ideal as cooling water pumps for marine engines, bilge pumps, deck wash pumps, fresh water pumps, fuel-transfer pumps and other applications. These pumps are also ideally suited on shore for emptying septic tanks and for flushing clean and filling water tanks.
