Frequently Asked Questions
Q: What types of fluid are compatible with the VQ Series Cartridge?
A: The standard cartridge supports Petroleum series oil, emulsification fluid, and water glycol-fluid. For phosphate ester fluid applications, please specify the "F3" prefix designation.
Q: What do the PC and PCT codes represent in the model designation?
A: "PC" designates the cartridge kit of a single pump or the shaft end of a double pump. "PCT" designates the cartridge kit of the cover end of a double pump.
Q: How is the rotation direction of the VQ series determined?
A: The rotation is viewed from the shaft end of the pump. "R" stands for right-hand (clockwise) rotation, and "L" stands for left-hand (counter-clockwise) rotation.
Q: What displacements are available for the 25VQ series?
A: The 25VQ series displacement options include 10, 12, 14, 15, 17, 19, 21, and 25 USgpm flow at 1200r/min and 0.69MPa.
Q: What is the standard design number for these cartridge kits?
A: The current standard design number for the 20VQ, 25VQ, 35VQ, and 45VQ series cartridge kits is 10.
