Product Information :

The Tuthill 6RCK2BN-A is a Cast Iron Rotary Gear Pump, Pump End Only, no motor, with Reversing Feature, Heavy-Duty version, Double Ball Bearing, Outboard Ball Bearing, A-type Tang Shaft, and 2 Inch NPT by 2 Inch NPT ports. This pump was designed for heavy duty service and has a double ball bearing with an inboard heavy-duty roller bearing. This pump is supplied with a mechanical seal capable of handling inlet pressures to 250 PSI at a standard 1725-RPM motor speed with a maximum discharge pressure of 300 PSI. The maximum differential for this pump is 150 PSI. This pump was designed for flange or foot mounting applications. They may also be adapter mounted to NEMA C face electric motor using the correct sized motor to pump mounting adapter. This pump has an outboard ball bearing and was specifically developed for use with belt drives or similar applications were a side load is applied to the pump shaft. 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 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 6RCK2BNA can be used in. This reliable internal gear pump is ideal for custom OEM lubricating, lowpressure hydraulic, transfer, circulating, burner oil and many other industrial pump applications, and can be used in Air Conditioning Compressors, Air Compressors, Gas Compressors, Transmissions, Engines, and Gearboxes. Many Original Equipment Manufacturers worldwide incorporate Tuthill internal gear pumps into their products for lubrication and transfer service. This widespread acceptance is a result of product performance and reliability. 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.
