ROTAN® Internal Gear Pumps

Geared to individual solutions

The ROTAN® internal gear pump provides favourable flow conditions, as the direction of the liquid flow is only changed slightly through the pump.

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.
