What is a 12-volt diaphragm pump?

A 12-volt diaphragm pump is a high-capability diaphragm pump that employs a 12-volt self-priming permanent magnet motor for superior spraying performance. Like all diaphragm pumps, a 12-volt diaphragm pump is a positive displacement pump. It uses the reciprocating action of a pliable diaphragm and shut-off valves—such as check valves, butterfly valves, or flap valves—to pump fluid through the system. The diaphragm itself is most commonly constructed out of rubber, Teflon, or thermoplastic materials. The diaphragm pump responds to alternating pressure changes in order to draw fluids between the chambers and force them out through a complete cycle. Diaphragm pumps do not require a lubricant due to the hermetic seal between the drive mechanism and the compression chamber. This allows the pump to transfer, compress, and discharge the fluid freely.

When to use a 12-volt diaphragm pump

Most 12-volt diaphragm pumps can produce up to 5.0 gallons of fluid per minute with a maximum pressure of 45 PSI. Most motors are not equipped with thermal protection, so it is recommended that the temperature of the liquid is kept below 140º F to protect the pump.

What can a 12-volt diaphragm pump be used for?

12-volt diaphragm pumps may be used for a variety of technical performance applications, including spot applications, broadcast spraying, metered pesticide applications, and for the application of water-based non-flammable sealants or stains for outdoor wood surfaces. These pumps are intended for use strictly with non-flammable products. Also, they should not be used to transfer any product intended for human consumption. Pumps should be used for only one product, to minimize the hazards of cross-contamination from residual chemicals and pesticides.
