Tuthill # 2RC2F-RH-7 Rotary Gear Pump

The Tuthill 2RC2F-RH-7 is a Cast Iron Rotary Gear Pump, Pump End Only, no motor, Flange Mount, with Reversing Feature, Viton Lip Seal, RH right-hand suction port (from shaft end view), standard shaft, Viton elastomers, and 1 Inch NPT by 1 Inch NPT ports. 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 have only two moving parts. Pumping action is based on a rotor, idler gear, and a cover cast with a crescent-shaped partition. 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 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 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.
