Product Information :

The Tuthill 2RC2F-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, A-type Tang Shaft, Viton elastomers, and 1 Inch NPT by 1 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 2CF26 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. This pump has only two moving parts. Pumping action is based on a rotor, idler gear, and a cover cast with a crescent-shaped partition. The space between the outside diameter of the idler and the inside diameter of the rotor is sealed by the crescent. Power applied to the rotor is transmitted to the idler gear with which it meshes. The liquid fills the spaces between the teeth of the idler and the rotor and is carried past the crescent partition through the pressure side of the pump. When the teeth mesh on the pressure side, the liquid is forced from the spaces and out through the discharge port. 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 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.

Applications

There are many applications that the Tuthill 2RC2FA788502 can be used in. Original Equipment Manufacturers worldwide incorporate these internal gear pumps into their products for lubrication and transfer service. It can be used in Air Conditioning Compressors, Gearboxes, Air Compressors, Gas Compressors, Engines, and Transmissions. This reliable internal gear pump is ideal for custom OEM lubricating, lowpressure hydraulic, transfer, circulating, burner oil and many other industrial pump applications. This pump incorporates Tuthill's unique Reversing Feature which allows positive reversing action without the use of valves. Port positions remain constant regardless of the direction of shaft rotation. It is ideal for use in power transmission applications where the drive shaft direction changes, but the direction of flow must remain constant. Other applications where shaft rotation is unknown, the reversing feature allows the customer to specify the suction and discharge ports. When shaft rotation changes from counterclockwise to clockwise, the idler carrier including the idler gear and crescent automatically rotates 180 degrees through the suction zone to the position shown in the drawing below. This changes the direction of the flow within the pump without changing port positions. On resumption of counterclockwise rotation, the crescent will swing back to the original position. This pump and motor unit must be properly aligned during installation and periodically checked, since misalignment may occur later due to abuse or other conditions. Pipe strain can force the pump and motor shafts out of alignment. Therefore, all piping to the pump must be properly supported. Do not allow the pump to act as a pipe support.
