Vickers 3520VQ25A5 1AA20 LH

Description & Features

A cast iron, double-displacement vane pump designed for demanding industrial duty, the Vickers 3520VQ25A5 1AA20 LH is part of the 3520VQ series built to handle high-pressure, high-speed hydraulic circuits. With a flow rate of approximately 176 litres per minute and Buna-N seals, it is well-suited for continuous-duty applications where volumetric efficiency and service life are critical considerations.

This pump is applicable across a broad range of industrial sectors, including plastics machinery, press and die casting equipment, machine tools, test equipment, primary metals processing, pulp and paper, wood processing, oil and gas, marine, and general industrial hydraulic systems. The left-hand (LH) configuration is an important selection factor when specifying for a particular drive arrangement.

Question by: Darryl J on May 1, 2025, 10:16 AM

Running a press setup and need to know if this pump can hold up under continuous duty, what kind of flow are we actually getting out of it?

Answer by: Customer Support on May 2, 2025, 6:40 PM

At roughly 176 litres per minute, there's solid output for high-demand press applications. The 3520VQ series was built specifically for continuous industrial duty, so it's not a pump you'd use in a light-cycle situation. Cast iron construction and Buna-N seals are what keep it running reliably over the long haul, which matters when downtime isn't an option on a production floor.
