Johnson Pump F4B-19 oil-diesel-water Pump 12V

The Johnson Pump F4B-19 Oil-Diesel-Water 12V is a self-priming flexible impeller pump designed for the transfer and circulation of water, oil, and diesel in boats and technical applications. This multifunction pump is engineered for liquid transfer, bilge pumping, deck washing, and hydraulic supply tasks in marine environments where a robust and reliable 12V-powered solution is required.

Its primary application is the pumping of fresh water, seawater, oil, and diesel fuel in marine systems and onboard maintenance operations. Thanks to its self-priming capability and oil-resistant impeller, it enables efficient fuel transfer, oil changes, water circulation, and bilge draining. It also helps reduce common issues such as loss of prime, complex maintenance requirements, or installation constraints, as it can be mounted in various positions without compromising hydraulic performance.

The Johnson Pump F4B-19 operates on a 12V power supply and delivers a flow rate of up to 48 litres per minute. It features a nitrile oil-resistant impeller and a brass pump head for enhanced durability when handling water and fuel applications. The pump offers a self-priming lift of up to 4 metres and a maximum continuous operating pressure of 0.6 bar. The motor incorporates integrated thermal protection to improve safety and service life in demanding applications. Its connections support 1" hose fittings or 1/2" BSP threaded connections, allowing easy integration into marine and technical hydraulic systems.

The product includes one Johnson Pump F4B-19 Oil-Diesel-Water 12V pump, ready for installation in liquid transfer and pumping systems. It does not include fittings, hoses, or additional hydraulic accessories except those supplied by the manufacturer.
