EIPR - Ring Pump
Structure of the circular pump EIPR
Radially and axially compensated Without crescent (without segments)
Design
System Eckerle EIPR, the new genaration of circular pumps, are gap compensated internal gear
pumps. The meshing length of the gear cogs causes an only slight pulsation of either the system
pressure and the volume flow rate, which is fundamental for silent operation.
Radial compensation
The radial compensation force is transferred from the compensation ring to the internal gear. In accordance to the operating
pressure the cogs of pinion shaft and internal gear achieve the sealing. This ‚roll gliding’ ensures high tightness but low friction
forces. The pressing force is very low.
Axial compensation
This pump type is equippel with axial discs for gap compensation. The sealing is due to a fixed disc against gear parts in operation.
