Cast Iron Gear Pump

Cast Iron Gear Pump - C991

Tailored specifically for wear resistance and long life in lubricating fluid service. They are designed to handle a wide range of fluids at temperatures to 400°F, at pressures up to 150 psi, and at shaft speeds to 1750 RPM. Viscous liquids require reduced shaft speeds.

Standard Lubricating Fluid Service: Shafting is 303 stainless steel, gearing is steel. Rugged ductile iron housings. High grade carbon-graphite bushing style bearings are used. The Standard Mechanical Shaft seal is a stainless cased Nitrile elastomer bellows and O-ring with carbon and ceramic wear faces. An optional fluoroelastomer mechanical seal with carbon and ceramic wear faces is also available. Recommended liquid temperature range is 32°F to 225°F (Nitrile) or 400°F (fluoroelastomer).

As with all external gear rotary pumps which operate based upon close running clearances, the presence of solid particles and abrasives can lead to premature wear and damage. Use suction screens or start-up strainers when necessary.
