Product Information :
The Tuthill 2RLEV is a Cast Iron Rotary Gear Pump, Pump End Only, no motor, with Reversing Feature, an Internal Relief Valve set to 55 PSI (can be adjusted in field), standard shaft, and 1/2 Inch NPT by 1/2 Inch NPT ports, replacement pump end only without a Motor. This pump is suitable for equipment, motor, or adapter mounting. Tuthill LE 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 has an internal relief valve, and the adjusting screw of the relief valve is located on the suction side of the pump. The internal relief valve on this pump is designed for over-pressure protection only. It is not intended as a flow control device or for any similar use. Continuous operation of the relief valve will result in excessive heat buildup within the pump cavity that could cause serious internal damage. Make certain the adjusting screw of the relief valve is located on the suction side of the pump. Unless otherwise specified at the time of order, this pump is supplied with the standard spring, with a range of 55-120 psi, set to provide full bypass relief at 55 psi. 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 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 2RLEV can be used in. Original Equipment Manufacturers worldwide incorporate these internal gear pumps into their products for lubrication and transfer service. These LubeTech Series pumps have set the industry standard for lubrication and circulation applications. This internal gear pump has been engineered to satisfy customers everchanging requirements throughout a wide range of applications. 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.
