Tuthill 0LEV-CC-7-88521 Pump and Motor

The Tuthill Pump # 0LEV-CC-7-88521 is a Cast Iron Rotary Gear Pump and motor unit, with an Internal Relief Valve set to 55 PSI (can be adjusted in field), Counter Clockwise rotation only (from shaft end view), standard shaft, Viton mechanical shaft seal and o-ring, Viton elastomers, and 1/2 Inch NPT by 1/2 Inch NPT ports, close coupled and assembled onto a 3/4 Horsepower, 1725 RPM, 208-230/460 Volts, Three Phase, TEFC (Totally Enclosed Fan Cooled), 56YZ Nema frame electric motor. This pump is suitable for equipment, motor, or adapter mounting. Tuthill LE 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 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 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.
