Conventionally pressure switch controlled pumps are an attractively priced solution. Jabsco 4 & 3 series enjoy the same 4 chamber diaphragm design and long life motors as the VSD models. Like all Jabsco water pressure pumps they are inherently quiet, self-priming and can run dry without damage. The 2.9 & 1.9 models suit craft with upto 3 hot and cold outlets, such as galley sink, hand basin and shower. The self-priming and dry running, three chamber diaphragm design has a built-in bypass that gives smooth pulsation free flow, even at lower outputs, making an accumulator tank non-essential.
