Designed for demanding industrial hydraulic circuits, the Vickers 3525VQ25A21 1AA20 LH is a left-hand rotation vane pump from the Vickers by Danfoss/Eaton VQ(H) Series. Built with a cast iron housing and Buna-N seals, it is constructed to handle high-pressure, high-speed service while maintaining strong volumetric efficiency across extended duty cycles.
With a flow rate of approximately 176 litres per minute, this pump is well suited for press machines, die casting equipment, machine tools, and plastics machinery, as well as applications in pulp and paper, primary metals, wood processing, oil and gas, marine, and general industrial sectors. The VQ(H) Series is recognized for longer service life in continuous-duty hydraulic systems where reliability and consistent output are critical.

Question by: Chad F on Sep 5, 2025, 12:18 PM
How long can I expect this pump to last if I'm running it pretty much all day, every day?
Answer by: Customer Support on Sep 7, 2025, 8:25 AM
The VQ(H) series is known for its longer service life in hydraulic systems that operate continuously, so it should hold up well under demanding duty cycles.
Question by: Rick S on Aug 12, 2025, 2:10 PM
Flow rate on this one is listed around 176 litres per minute, that holding up in continuous press machine or die casting setups, or is that more of a peak figure?
Answer by: Customer Support on Aug 14, 2025, 6:37 AM
For continuous-duty applications like press machines and die casting equipment, the VQ(H) Series was built with exactly that kind of workload in mind. The 176 litre per minute flow rate reflects the pump's operating output, and the series carries a reputation for strong volumetric efficiency even over extended duty cycles. Cast iron construction and Buna-N seals help it hold up under the high-pressure, high-speed conditions those environments throw at it regularly.
