Question by: Stan K on Dec 8, 2025, 8:58 PM
Can this vane pump handle running all day long in a plastics factory?
Answer by: Customer Support on Dec 10, 2025, 8:31 AM
Built for demanding applications, the Vickers 3525VQ30A21 11AA20 is designed with features like extended operating life and high volumetric efficiency to ensure reliable performance in continuous-use environments like plastics machinery.
Question by: Daryl B on May 17, 2025, 8:20 AM
Flow rate on this one shows over 215 liters a minute, is that the kind of output you'd expect runnin it on press machine or die casting work, or is that more suited to bigger setups?
Answer by: Customer Support on May 18, 2025, 2:02 PM
For press machines and die casting, that flow rate is well within the range where this pump earns its keep. At 215-plus liters per minute, it's built to keep up with the high-demand cycles those applications throw at it. The cast iron construction and the high-pressure, high-speed design mean it's not just moving volume, it's doing it consistently without wearing down fast. Volumetric efficiency is one of the standout traits of this VQ series, so you're not losing much between what goes in and what you actually get out at the work end.
