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. The Rotan internal gear pump provides favourable flow conditions, because the direction of the liquid flow is only changed slightly through the pump. This means that superior self-priming capability and gentle liquid handling are achieved, and also that highly viscous liquids may be pumped. Rotan pumps offer the following additional advantages: Pumping in either direction. Easy maintenance and inspection based on the modular design Sturdy and uncomplicated construction with only two rotating parts and one shaft seal Genuine back-pull-out design. Large choice of configurations available as standard. Every Rotan pump is hydrostatically and performance tested and receives its own certificate before leaving the factory. It is DESMI ROTAN's policy to offer solutions tailored to the customer's need, followed up by a first-class after sales service. ROTAN GP ROTAN HD ROTAN PD ROTAN CD ROTAN MD
