Product Description

Quad DC Pressure Controlled Pump, 3/4" Hose Barb, 45 PSI Switch, No. 3 Cam

The Flojet 04300143A (4300 143) electric pump is a self-priming diaphragm pump with a 12 volt D.C. (12 VDC) motor. It offers pressure switch control and is capable of pressures up to 45 PSI (3.1 bar). The pump self-primes up to 8 vertical feet. It handles water-like and viscous liquids up to 250 cP.

This Flojet on-demand pump has a Santoprene diaphragm and EPDM valves. This model is similar to the following Flojet pumps: 04300504A04300142A, and 04300500A. These models have different elastomer materials for working with different types of chemicals.

This electric pump has a chemical resistant polypropylene head that helps ensure longevity and long life. Quick-connect plug-in ports on the pump's head make it easy to install the pump. The pump head's four-piston design delivers higher flow rates, which enhances the pump's smooth and efficient performance. Overall, this on-demand pump has a compact design for easy handling and installation. Plus it's well built to make troubleshooting simple.

This pressure controlled pump is a part of the Quad industrial series of diaphragm pumps. Able to run dry without damage, this pump is intended for intermittent duty cycles but can be run continuously for short time periods. The more the pump is run, the shorter the life expectancy. If you're looking for a 12v continuous duty water pump, consider the Flojet R3B21502A.
