Gorman-Rupp rotary gear pumps

Click2Contact

Gorman-Rupp’s range of rotary gear pumps is suitable for handling process fluids or lubrication. Because of their modular design, the pumps can be configured to handle thin or viscous fluids, corrosive and/or abrasive fluids, and fluids with temperatures from -51 to +358°C. Flows of just a few litres per minute up to 2200 L/min can be achieved.

The heavy-duty series is capable of handling viscosities to 440,000 centistokes and develop pressures to 20.7 bar. A large ‘end feed’ area allows the pumps to run at pole speeds for many applications, removing the need for reduction gearboxes — minimising capital outlay and reducing maintenance for the life of the equipment.

The pumps include many features to promote longer service life, including an automatic idler pin lubrication system that cools and lubricates this usually hot and high-wearing part of the pump. The ‘internal seal vent’ system meanwhile ensures cooling of the seal area but also reduces pressure in the seal cavity, reducing load and heat from the seal faces and increasing seal life.

The pump is user-friendly for operators with features such as the ‘back pull-out design’ to allow service and maintenance without disconnecting the pump housing from piping and the ‘adjustable no-leak pressure relief valve’ which allows operators to adjust the valve during operation without leaking high-temperature or corrosive fluid.

The series also has a variety of sealing options. These include, but are not limited to: cartridge seals; balanced seals; double or tandem seals; seals with carbon, silicon carbide or tungsten carbide faces; and seals with viton, neoprene, Chemraz or kalrez elastomers; and gland packing or triple lip seals.

Heat-sensitive liquids can be catered for with heating jackets built into the pump head and body to keep those products molten while pumping. Depending on the product to be pumped, bushings can be bronze, carbon graphite, silicon carbide or tungsten.

The pumps are suitable for a wide range of applications including the pumping of hydrocarbons; viscous fluids such as adhesives and greases, acids, solvents, salts and caustics; paper-mill liquids; food products; abrasive products such as paints, inks, waste oils and paper coatings; and more.
