Flojet 4000 Series Demand Pumps

Flojet developed the quad pumps to deliver higher flows up to 19 LPM using a four-piston design with excellent self-priming capability. Built-in pressure switch automatically starts and stops pump instantaneously when discharge valve opens and closes. Compact design and plug-in port fittings make installation easy. Can run dry without damage and handle liquids up to 54° C (130° F) • No metal contact with liquid being pumped. Ball bearing drive throughout pump and motor assures longer pump life. Excellent self-priming capability. Pump may be located above the liquid level. Powerful, permanent magnet motor with low current draw and long life brushes.
