Frequently Asked Questions
Q:
What is the difference between PC and PCT cartridge kits in VQ series?
PC represents the cartridge kit designed for the shaft end of single or double pumps, while PCT represents the cartridge kit designed specifically for the cover end of double pumps.
Q:
How do I determine the rotation direction of the VQ series cartridge?
The rotation is viewed from the shaft end of the pump. "R" designates right-hand rotation (clockwise), and "L" designates left-hand rotation (counter-clockwise).
Q:
What types of hydraulic fluids are compatible with these cartridge kits?
Standard kits (no-marking) are compatible with petroleum series oil, emulsification fluid, and water glycol-fluid. The "F3" marked kits are designed for phosphate ester fluids.
Q:
Are the displacement values identical across different VQ pump series?
No, displacement options vary by series. For instance, the 20VQ series ranges from 2 to 14 USgpm, while the larger 45VQ series ranges from 42 to 75 USgpm at 1200 r/min.
Q:
What does the design number "10" indicate?
The design number "10" indicates the specific design version of the cartridge. It is essential for ensuring exact compatibility when ordering replacement parts.
