Product Information :

The Tuthill 5LEK-A is a Cast Iron Rotary Gear Pump, Pump End Only, no motor, with Outboard Ball Bearing, A type Tang Shaft, and 1 Inch NPT by 1 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 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.
