KCL’s VQ, DVQ, and HVQ Series vane pumps are engineered to match the performance benchmarks of Vickers (Eaton) hydraulic pumps — not approximately, but specifically against the metrics that determine how a pump actually performs in the field: efficiency, noise, vibration, operating temperature, and service life. For customers currently specifying Vickers or Eaton components, this series offers a verified, interchangeable alternative without the compromises that “generic equivalent” pumps often carry.

Engineered Against the Right Benchmarks

It’s easy for a manufacturer to claim their pump is “equivalent” to an industry-leading brand. It’s harder to actually engineer to that standard and prove it. KCL’s VQ Series was developed with a specific target: matching Vickers (Eaton) pumps not just on displacement and pressure rating, but on the operational characteristics that determine whether a pump is genuinely reliable in continuous industrial use.

Efficiency: The VQ Series is engineered to deliver volumetric and overall efficiency in line with Vickers (Eaton) equivalents, meaning you get the flow output you’re expecting at the pressure you’re operating at, without unexpected losses that drive up your system’s energy costs.

Noise: Vane pump noise is a genuine consideration in many industrial environments, particularly where operators work in close proximity to hydraulic power units for extended periods. The VQ Series is engineered to match the noise characteristics of the Vickers (Eaton) benchmark, so switching to KCL doesn’t mean introducing a noisier component into an otherwise quiet system.

Vibration: Excessive vibration doesn’t just create noise — it accelerates wear on seals, fittings, and mounting hardware throughout your hydraulic system. Matching Vickers (Eaton) vibration benchmarks means the VQ Series won’t introduce new maintenance burdens elsewhere in your system.

Temperature: Operating temperature directly affects fluid viscosity, seal life, and overall system efficiency. The VQ Series is engineered to run within the same temperature parameters as its Vickers (Eaton) equivalent, supporting consistent performance across your expected operating envelope.

Service Life: Ultimately, all of the above characteristics feed into service life — the metric that determines your total cost of ownership. By matching Vickers (Eaton) benchmarks across efficiency, noise, vibration, and temperature, the VQ Series is built to deliver comparable service life, not just comparable specifications on a data sheet.

Three Configurations to Match Your Circuit

VQ Series — the standard single-pump configuration, suited to a wide range of general industrial hydraulic circuits requiring high-pressure vane pump performance.

DVQ Series — a double-pump configuration, combining two pumping elements into a single housing for applications requiring two independent circuits from one drive, similar in principle to our KT Denison-Type Double Pump line.

HVQ Series — a high-pressure variant of the core VQ platform, engineered for applications operating at the upper end of the pressure range where standard vane pump designs begin to show their limitations.

Built for Continuous-Duty Applications

The VQ/DVQ/HVQ Series is particularly well suited to applications where consistent performance under sustained, continuous operation is non-negotiable — production equipment running multiple shifts, industrial power units supporting critical processes, and any application where an unplanned pump failure translates directly into costly downtime.

Typical Applications

• General industrial hydraulic power units requiring high-pressure vane pump performance
• Machine tools and production equipment currently specified with Vickers or Eaton components
• Multi-circuit systems requiring the DVQ double-pump configuration
• High-pressure applications at the upper end of standard vane pump capability, suited to the HVQ variant

Why Choose KCL’s VQ/DVQ/HVQ Series

If your hydraulic system was originally engineered around Vickers or Eaton vane pump specifications, switching suppliers shouldn’t mean re-engineering your circuit or accepting a downgrade in performance. KCL’s VQ/DVQ/HVQ Series was developed specifically to eliminate that trade-off — giving you a component that has been engineered and verified against the exact benchmarks your system was designed around, manufactured under our ISO 9001:2015 certified quality systems, and backed by more than four decades of dedicated hydraulic pump manufacturing.
