Tuthill # 4RC2F-C-RH-A-7-88502 Rotary Gear Pump and Motor unit

The Tuthill 4RC2F-C-RH-A-7-88502 is a Cast Iron Rotary Gear Pump and Motor unit, close coupled pump and motor assembly, with Reversing Feature, Viton Lip Seal, Clockwise rotation only (from shaft end view), RH right-hand suction port (from shaft end view), A-type Tang Shaft, Viton elastomers, and 1-1/2 Inch NPT by 1-1/2 Inch NPT ports. This pump is close coupled and assembled onto a 3/4 Horsepower, 1125 RPM, 208-230/460 Volts, Three Phase, TEFC (Totally Enclosed Fan Cooled), 56CZ FRAME electric motor. The motor on this pump and motor assembly is a proprietary Tuthill motor with an internal coupling hub making for an extremely compact rotary gear pump and motor. This pump and motor assembly includes the 3CF26 Adapter. This pump was specifically developed for flange mounting applications and for close coupling to Tuthill's special motors to provide extremely compact close-coupled combinations. This pump is supplied with a single spring-loaded lip seal, and can handle inlet pressures to 25 PSI, and has a maximum differential capability of 100 PSI. Tuthill CF Series cast iron pumps employ the internal gear pumping principle. There are only two moving parts, and the pumping action is based on a rotor, idler gear, and crescent shaped partition cast integral with the cover. This pump features a unique reversing feature design. This design is ideal for rotating equipment and power transmission where direction of flow must remain consistent, even when shaft rotation changes. This pump has an RH right-hand suction port designation from the shaft end view. This pump can be driven in either direction of rotation, unless outfitted with an internal relief valve. This pump does NOT have an internal relief valve, so an external relief valve should be added somewhere on the discharge piping. Please note that this pump is a positive displacement pump and as the pump rotates, liquid is positively delivered to the discharge side of the pump. If the discharge line is closed off, pressure will increase until the drive stalls and/or fails, the pump breaks or ruptures, or the piping bursts. To prevent this from happening, the use of a pressure relief valve is required, or use of an in-line safety relief valve, pressure shutdown switch or other similar device. A relief valve that directs the flow back to the supply tank is recommended. This pump should not be used for handling plain water, corrosive or abrasive liquids or liquids not possessing adequate lubricity. Do not run the pump dry, as this could cause severe damage to the internal seal, bushings and/or metal parts.
