Johnson Pump F4B-9 Impeller Pump OEM Flange Mount for Engine Cooling and Water Handling

F4B-9 Impeller Pump OEM - Flange Mount

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 the water up to as much as 3 meters. Thus a flexible impeller pump being used for engine cooling needs not 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 freshwater applications, the standard long-lasting neoprene rubber impeller is used. Both the impeller and the seals depend upon the water for lubrication and will soon burn out if run dry.

Features:

• Flange mount for engines such as: Panda 12000 NE PMS Kubota, Panda 6000 ND PMS Kubota, Panda 8000 NE PMS Kubota, Panda 9000 ND PMS Kubota


• A general feature of all flexible impeller pumps is that they cannot be permitted to run dry for more than 30 seconds


• Wearing parts are easily replaceable for all standard models

Applications:

• Engine cooling raw water handling


• Freshwater handling

Specifications:

• Port size: (inch) 3/4" hose


• Mount Type: Flange


• CAM: Full 1/1


• Lip seal


• Material: Bronze

Cooling Capacity:

The required output of the cooling pump raw water as well as fresh water handling is related to:

• Engine type: (gasoline or diesel)


• Type of cooling system (size of heat exchanger)


• Water cooled engine oil, reverse gear, exhaust system

The Johnson Pump F4B-9 Impeller Pump OEM with flange mount provides a reliable solution for raw water and freshwater applications in marine and engine cooling systems. Designed with a flexible impeller, this pump features self-priming capabilities, allowing it to lift water up to 10 feet without manual assistance. Its efficient operation makes it suitable for engine cooling, raw water intake, and other water transfer needs. The pump's bronze construction ensures durability and resistance to corrosion, making it an excellent choice for demanding environments. The neoprene rubber impeller and lip seals are designed for longevity, but they require water for lubrication and should not be run dry to prevent damage. This model's flange mount simplifies installation on compatible engines such as Panda and Kubota models, ensuring a secure and stable connection. The pump is equipped with a 3/4-inch hose port, supporting versatile connection options for various plumbing setups.

Features:

• Flange mount for engines including Panda and Kubota models

• Self-priming capability allows lifting water up to approximately 10 feet

• Bronze construction ensures durability and corrosion resistance

• Neoprene rubber impeller suitable for raw and freshwater applications

• Lip seal design for reliable operation

• Wearing parts are easily replaceable for maintenance ease

• Cannot operate dry for more than 30 seconds to prevent damage
