Omega FPUD300 Series

Motor Driven Drum Pumps with Corrosion-Resistant Construction

More details

OMEGA’s FPUD300 Series drum pumps can empty a wide variety of containers in various applications. Motor types available are singlephase, 115 or 230 Vac, 50/60 Hz, continuous duty; and air driven.

Both the FPUD311 and FPUD321 electric motors are open drip-proof (ODP), while the FPUD362 is a totally enclosed fan-cooled (TEFC) motor.

All three AC motors are thermaloverload protected with a manual reset, and all three include internal cooling fan, built-in on/off switch, 3.6 m (12'), three-wire cord; both 115 Vac motors include a grounded wall plug.

The air operated unit has a ¼ MNPT fitting for hooking up to a customersupplied air hose, and includes a flow-regulating valve and muffler. An optional air lubricator/filter assembly is also available.

When pumping flammable or combustible materials, or for work in explosive environments use the FPUD331 air motor with a stainless steel tube.

FPUD3-P Series tubes include a variable orifice on the outlet to limit flows to 10, 20, 30, or 40 GPM. Refer to the performance curve graphs on next page for flow rate vs. discharge head data, and flow rate vs time for the rechargeable battery model. All FPUD3 Series pump tubes are sealless to insure leakproof operation. See tubing products in section T.
