Heavy duty internal gear pump


For heavy duty pump applications involving viscous liquids, the Rotan range of heavy duty gear pumps are an ideal option to consider. Unlike external gear pumps which have two gears running in parallel formation, the internal gear pump has a large driving gear, with a smaller offset idler gear running within. This design inceases the displacement volume while maintaining the positive displacement properties desirable in a gear pump.

Rotan gear pumps are ideal for heavy duty applications becuase for their robust design. Pumps require minimal maintenance and are designed for long periods of operation. Pumps options inlcude jacketing to maintain liquid temperature via steam/hot water, single and double mechanical seals, magnetic drive, and flush systems.

Complementing their viscous liquid handling properties, a wide range of both internal and external materials can be sourced to handle both inert and chemically active fluids. Pump casing materials include; cast iron, cast steel, cast Stainless Steel, and other materials on request.
