We are importers of replacement Cam rings for the below mentioned Vickers pump models:
20V/VQ (5,8,11,12,14 GPM) 25V/VQ (12,14,17,21 GPM)
35V/VQ (25,30,35,38 GPM) 45V/VQ (42,50,60 GPM)
Theese Cam rings have the same tolerances as Vickers make cam rings and by replacing it can restore the pump performance.
