Tuthill # 4C2FV-CC-LH-A-7-89255 Rotary Gear Pump and Motor unit

The Tuthill 4C2FV-CC-LH-A-7-89255 is a Cast Iron Rotary Gear Pump and Motor unit, close coupled pump and motor assembly, with a Viton Lip Seal, Internal Relief Valve, Relief valve is set at 90 PSI (can be adjusted in field), Counter Clockwise rotation only (from shaft end view), LH left-hand suction port (from shaft end view), A-type Tang Shaft, Viton elastomers, and 1-1/2 Inch NPT by 1-1/2 Inch NPT ports. This pump is close coupled and assembled onto a 1-1/2 Horsepower, 1725 RPM, 208-230/460 Volts, Three Phase, TEFC (Totally Enclosed Fan Cooled), 184CZ 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 3CF26 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. 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 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 30-225 psi, set to provide full bypass relief at 90 psi. This pump has an LH left-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.
