This pump is close coupled and assembled onto a 1/4 Horsepower, 1725 RPM, 208-230/460 Volts, Three Phase, TEFC (Totally Enclosed Fan Cooled), 48YZ FRAME electric motor. Tuthill 4000 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 40-70 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.
