Tuthill # 4104-A-88604 Rotary Gear Pump

The Tuthill 4104-A-88604 is a Cast Iron Rotary Gear Pump and Motor unit, close coupled pump and motor assembly, with a mechanical seal and carbon graphite idler and housing bushings, A type Tang Shaft, 1/2 Inch NPT by 1/2 Inch NPT ports, rated for a maximum flow of 2. 7 GPM at 1750 RPM. This pump is close coupled and assembled onto a 1/2 Horsepower, 1725 RPM, 208-230/460 Volts, Three Phase, XP, 56YZ FRAME electric motor. with 1/2 Inch NPT by 1/2 Inch NPT Ports, close coupled to a Close coupled to a 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 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.
