Frequently Asked Questions (FAQ)
Q1: What fluids are compatible with the VQ Series Double Vane Pumps?
By default, standard VQ series pumps are compatible with petroleum-based series oils, emulsification fluids, and water glycol fluids. For phosphate ester fluids, the designated "F3-" prefix model should be specified.
Q2: How do I interpret the flow codes in the model designation?
The flow code numbers (e.g., 38 for the shaft end, or 17 for the cover end) represent the USgpm flow rate measured at 1200 r/min and 0.69 MPa.
Q3: What mounting options are available for VQ double vane pumps?
The pumps support Flange Mounting as standard (no marking in the code structure) and Foot Mounting (designated by the letter "F" in the installation type code).
Q4: Are the outlet positions of the VQ series adjustable?
Yes, the outlet positions can be customized relative to the inlet position. Depending on the model configuration (e.g., 4535VQ vs other series), you can select options like 45°, 90°, 135° CW/CCW, opposite, or inline orientations.
Q5: What are the standard shaft configurations available?
The VQ series features multiple shaft options including Straight Key (Code 1), Heavy Duty (HD) Straight Key (Code 86), and Spline shafts (Code 11).
Q6: How much do the double pump assemblies weigh compared to single pumps?
Double pump weights range from 23.0 kg (for 2520VQ series) up to 95.0 kg (for SQP43 series), which is higher than single pump configurations that typically range from 13.0 kg to 65.0 kg depending on the frame size.
