ROTAN® internal gear pumps
ROTAN® positive displacement internal gear pumps for low- and high-viscosity liquids, including marine lube oil and fuel duties.
Description
ROTAN® internal gear pumps are positive displacement pumps using a driven outer rotor, an internally meshing idler gear and a crescent-shaped partition separating suction and discharge. A fixed volume is displaced each revolution, giving steady, controlled flow regardless of system pressure variations. A ROTAN testbed is located at DESMI headquarters in Nørresundby, Denmark.
Key features
- Handles both low- and high-viscosity liquids
- Steady, controlled flow independent of pressure variations
Applications
- Marine lube oil and fuel duties
