High Quality Electric Water Pumps, Electric Pump Self Priming Pump For Sea Water
11.3LPM/3.0GPM 55PSI
DescriptionR
un dry without damage (Run Dry Capability) Quick-connect plug-in ports for easy installation (Hose Kit Included) Self-priming Ignition & Thermally Protected SpecificationsHow a Diaphragm Pump Works:
1. The pump is driven by an AC or DC motor
2. In front of the motor is a valve assembly containing two to five valve pump chambers. Each valve chamber has a diaphragm behind it in the lower pump housing. As the motor shaft turns, an internal cam positioned behind the diaphragms causes the diaphragms to be pushed forward, then back in a continuous sequence creating a suction. As this suction builds, fluid is pulled through the inlet, through the various valve chamber check valves to the outlet
3. The volume of flow is determined by several factors including: the number and size of the pump chambers, cam offset, operating pressure, fluid viscosity
Application:1. Yacht / RV/Caravan pressurized water system 2. Sprayer fixtures (Vehicle-mounted sprayers, electric sprayer)3. Clean machine, Humidifier, Water purification, Medical apparatus 4. Food beverage filling & liquid transfer5. Any other pressurization system
