Frequently Asked Questions (FAQ)
What is the VQ Series Cartridge Kit used for?
The VQ Series Cartridge Kit is designed as a replacement part for Eaton Vickers hydraulic vane pumps. It allows for quick and easy servicing of the pump's inner rotating elements (including the rotor, vanes, and cam ring) without needing to replace the entire pump housing.
How do I identify the correct rotation for my VQ cartridge?
The rotation is determined by viewing the pump from the shaft end. In the model designation code, "R" stands for Right-Hand (clockwise) rotation, and "L" (or left-hand) represents Counter-Clockwise rotation.
What fluid types are compatible with these cartridge kits?
Standard cartridges (no prefix marking) are compatible with petroleum-based series oils, water-glycol fluids, and emulsification fluids. For systems utilizing synthetic phosphate ester fluids, you must specify the "F3-" prefix version.
What is the difference between PC and PCT cartridge designations?
"PC" designates a cartridge kit built for single pumps or the shaft end of double pumps. "PCT" designates a cartridge kit designed specifically for the cover end of double pumps.
How is the displacement value measured in the VQ series?
The displacement value in the model designation represents the nominal flow rate in USgpm measured at 1200 r/min and a pressure of 0.69 MPa.
