Model 7865645 Water Pressure Pump 2.4
12V DC five chamber positive displacement diaphragm pump.
Typical applications
This pump is the ideal choice for pressurizing water
in a closed system such as that found in a boat or
in a recreational vehicle.
It can easily build the pressure required for a
pressurized water supply system.
Features
• Quiet operation
• Smooth flowing
• Self priming
• Integrated pressure switch turns pump on and off
automatically when tap is opened and closed
• Dry running without damage
• Low power consumption
• Quick disconnect fittings
Working principle
As the pump runs, pressure builds until reaching
2.8 bar/41 psi. At this point, the integrated pressure
switch automatically shuts the pump off.
The pump is equipped with positively checking
outlet valves which ensure that the pressure is
maintained after the pump shuts off.
When water is demanded (at the faucet, shower,
etc.) the pressure decreases. After a moderate
drop in pressure, the integrated pressure switch
automatically turns the pump back on.
Due to it's durable construction and thoughtful de-
sign, the pump will provide many years of service.
Important! The pressure setting of this pump is
made at the factory. Warranty invalidated by
pressure switch interference.
