HomeRotan internal gear pumps
The internal gear pump principle was developed in 1915 by a Danish American.
In 1921, he licensed a Danish company to manufacture the pumps, which have been continuously marketed worldwide under the ROTAN® name. The unique, modular concept of ROTAN® pumps is generally recognized as the most advanced internal gear pump design available today.
ROTAN® GP - General Purpose Pumps
Pumps in cast iron, for clean, non-abrasive liquids.
The simple and compact construction makes it a low-cost pump, often used in modified versions by OEM customers. A close-coupled OEM model is also available.
GP pumps are designed for use with IEC or NEMA flange motors. Available with 90° angular configuration. Common applications; clean oil, glycol, vegetable oil, solvents, lube oil, waste oil, fish oil
ROTAN® HD - Heavy Duty Pumps
Pumps in cast iron, for a wide range of viscous, non-corrosive liquids. HD pumps are specifically designed for difficult applications and those involving high viscosity liquids.
HD pumps are known by their sturdy and simple construction. Available with 90° angular configuration. Common applications; oil, asphalt, chocolate, paint/lacquer, molasses, soap, additives, polyol.
ROTAN® PD - Petrochemical Duty Pumps
PD pumps are designed for refinery and petrochemical applications, all pressure-containing components are in carbon steel. Design pressure according to ANSI 300 Lbs or Pn40.PD pumps meet API 676 standards with only a few exceptions.Available with 90° angular configurations. Common applications; fuel, oil, gasoline, lube oil, grease, other hydrocarbon based fluids.
ROTAN® CD - Chemical Duty Pumps
CD pumps are designed for handling corrosive liquids, primarily found in the chemical processing, food and pharmaceutical industries. Available with 90° angular configuration. Common applications; organic acid, fatty acid, alkali, caustic soda, polymer solutions, soap, shampoo.
ROTAN® ED - Environmental Duty Pumps
Magnetically coupled pumps for ultimate protection against leakage.
As only minimal maintenance is necessary, ED pumps will be a very economical solution compared with traditionally sealed pumps, especially where the application requires the use of double mechanical shaft seals. Common applications; isocyanate, solvents, hazardous organic liquids, printing ink, resin, pitch, alkyd resin, soyabean oil, linseed oil, monomers, polyol,corn syrup.
ROTAN® - Chocolate Pumps
A speciality within the ROTAN® range is the ROTAN® chocolate pump for pumping cocoa mass and chocolate. Configuration with special clearances between the fixed and the rotating parts to protect the chocolate from excessive temperatures.
ROTAN® - Asphalt pumps
ROTAN® has for many years supplied pumps to the asphalt industry, and being a pump manufacturer we are too experienced to claim that it is easy to pump asphalt. We do however claim to have the best solution for most applications within this industry, as our experience as well as feedback from customers have been used for improvement and development. Electrical heating as an alternative to heating by liquid/steam, is the most recent result of this. The heating source is a temperature probe, mounted in the idler pin of the pump.
