Frequently Asked Questions (FAQ)
Q
What does the "F3" prefix signify in the VQ Series Model Designation?
The "F3" prefix indicates that the pump is designed for use with phosphate ester fluids. If there is no marking, the pump is suitable for petroleum series oil, emulsification fluid, and water glycol fluid.
Q
How do I determine the outlet positions for VQ series double pumps?
Outlet positions are viewed directly from the cover end of the pump. The configuration designates the positioning of Outlet NO.1 and Outlet NO.2 relative to the inlet (e.g., opposite, inline, or at specific angles like 90° or 135° CW/CCW).
Q
What is the weight difference between single and double VQ series pumps?
Single VQ pumps (like the 25VQ) typically weigh around 15.0 Kg, whereas double VQ pumps (such as the 3525VQ or 4525VQ) have a higher weight range, typically between 23.0 Kg and 58.0 Kg, depending on the specific series combination.
Q
Which shaft types are available for the VQ series double pumps?
According to the model designation guide, the standard shaft options include Shaft type "1" (Straight Key), "86" (Heavy Duty Straight Key), and "11" (Spline).
Q
What installation mounting options are supported?
The installation type can be standard Flange Mounting (indicated by no marking in the model code) or Foot Mounting (indicated by the letter "F").
