The Tuthill 3CK2B-CC-A-7 is a Cast Iron Rotary Gear Pump, Pump End Only, no motor, Heavy-Duty version, with Double Ball Bearing, Viton Mechanical Seal, Counter Clockwise rotation only (from shaft end view), A-type Tang Shaft, Viton elastomers, and 1-1/4 Inch NPT by 1-1/4 Inch NPT ports. This pump was designed for heavy duty service and has a double ball bearing with an inboard heavy-duty roller bearing. This pump is supplied with a mechanical seal capable of handling inlet pressures to 250 PSI at a standard 1725-RPM motor speed with a maximum discharge pressure of 300 PSI. The maximum differential for this pump is 150 PSI. This pump was designed for flange or foot mounting applications. They may also be adapter mounted to NEMA C face electric motor using the correct sized motor to pump mounting adapter. 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 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.
