Johnson Pumps | Aqua Jet Flow Master 5.0 Water Pressure System, 5.0 GPM, 12V DC

Regular price $354.28


A revolutionary design, the Flow Master 5.0 is a five-chamber positive displacement diaphragm pump that is an ideal choice for pressurizing water in a closed system such as that found in a boat or recreational vehicles.

The digital controller adjusts water flow as the demand changes while maintaining a constant line pressure and a very smooth flow.
The unique variable flow feature of the Flow Master pump allows the pump to be mounted without an accumulator tank and still maintain an even flow at the fixture, regardless if one or multiple taps are being used.
Always, use a PUMProtector inlet strainer before the pump intake.
