Versatile and Efficient Marine Pumping

The Johnson Pump F5B-9 Impeller Pump OEM - Flange Mount is a superior choice for your raw and freshwater pumping needs. Designed for engine cooling and general marine applications, this flexible impeller pump excels in self-priming and handling various fluid types, including those containing large solids, without clogging or damage.

Benefits of the Flexible Impeller Design

• Self-Priming Capability: The flexible impeller creates a vacuum as the vanes depress and rebound, lifting water up to 3 meters even from a dry start. This eliminates the need for manual priming or positioning the pump below the waterline.
• Handling Large Solids: The pump can pass fairly large solids, reducing the need for pre-filtering the incoming fluid and ensuring smooth operation.
• Reliable Engine Cooling: Specifically designed for engine cooling, this pump ensures efficient raw water handling and supports both gasoline and diesel engines.
• Long-Lasting Performance: Constructed with a durable neoprene rubber impeller, the pump offers reliable performance in general raw or freshwater applications.

Key Features and Advantages

• Crankshaft Style Cooling Pump: Suitable for older style small block GM marine engines such as American Diesel & Bomac Marine.
• Accessible Impeller Design: Easy to access for maintenance and replacement, ensuring minimal downtime.
• Run Dry Limitations: While highly efficient, it’s important to note that flexible impeller pumps should not run dry for more than 30 seconds to avoid damage.
• Replaceable Wearing Parts: All standard models come with easily replaceable parts, enhancing the longevity and serviceability of the pump.

Ideal Applications

• Engine Cooling: Efficiently manages raw water for cooling marine engines.
• Freshwater Handling: Suitable for a variety of freshwater applications on board.
