Nachi VDC variable displacement vane pump, 16.7 cc/rev, with pressure control from 70 to 140 bar and flange mounting.
The VDC is the Nachi variable displacement vane pump series for higher pressures, up to 14 MPa. As with other compensated pumps, the flow drops by itself when the circuit reaches the set pressure.
The suffix E6234A identifies the version; compare it with the rating plate of the pump you are replacing. The Nachi VDC catalogue is in the attachments.
