The Flojet VersiJet, MPN Q40FF-118S-2P, is a 115 V AC diaphragm pump for transfer, spraying, cooling, circulation, filtration and dispensing. It delivers 4 GPM (15 LPM) at open flow, and its pressure switch shuts it off at 60 PSI. It is a mains-powered pump, not a 12 V RV fresh-water pump.

The pump draws up to 1.3 A at 60 PSI on 104–126 V AC. It self-primes up to 8 ft of dry lift, can run dry and has an internal bypass. Fluid temperature is rated 32–140 °F, and the maximum inlet pressure is 30 PSI. Ports are two 3/4 in straight hose barbs with tool-free quick connects.

The upper housing is glass-filled polypropylene and the lower housing cast aluminum, with a Santoprene diaphragm, EPDM valves and seals and stainless fasteners. It is IPX6 rated and UR listed, and our store listing says it replaces Flojet 04300042A and 04300043A. Duty is intermittent. Flojet does not list approved fluids in the sources we checked, so confirm chemical compatibility with us.

Fit & Use Guides

Match the Accessory to Its Surface and Intended Job

The VersiJet is a 115 V AC pump for transfer and spraying. Check these six points before you buy.

AC Diaphragm Pump or 12 V Water Pump?

An AC diaphragm pump runs from mains power and suits workshop transfer, spraying and dispensing jobs. A 12 V water pump runs from an RV or boat battery and supplies the onboard fresh-water system.

Choose the VersiJet only where 115 V AC power is available and the fluid suits its materials. For an RV's fresh-water system, use a 12 V pump made for potable water.
