Product Description

SEAFLO 12V Water Pump

Run dry without damage  (Run Dry Capability)   
Quick-connect plug-in ports for easy installation (Hose Kit Included) 
Ignition & Thermally Protected 

How 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

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 transfer
5. Any other pressurization system
