KCL’s VPKC Series is a high-pressure variable vane pump engineered for full compatibility with Bosch Rexroth’s VPV series, rated to a maximum pressure of 306 bar. For system designers and OEMs currently specifying Rexroth components, the VPKC offers a verified, interchangeable alternative that delivers the variable flow control modern hydraulic circuits demand — without the compromises that come with lower-tier “equivalent” products.

Why Variable Displacement Matters

Fixed displacement pumps deliver the same flow output regardless of what your downstream circuit actually needs at any given moment — which means excess flow either gets diverted through a relief valve (wasting energy as heat) or the system has to be oversized to accommodate peak demand even when average demand is much lower. Variable displacement pumps like the VPKC solve this by adjusting output flow to match real-time system demand, delivering meaningful energy savings over the operational life of your equipment.

For facilities where energy costs are a genuine line-item concern — and increasingly, for facilities with sustainability targets tied to energy consumption — the efficiency gains from variable displacement technology compound significantly over years of continuous operation.

Rated for Serious Pressure Demands

At a maximum pressure rating of 306 bar, the VPKC Series is built for hydraulic circuits operating at the higher end of industrial pressure requirements. This makes it suitable for demanding applications where lower-pressure variable pumps simply aren’t rated to perform — heavy industrial machinery, high-force clamping and pressing applications, and hydraulic power units feeding multiple high-demand circuits.

Full Compatibility with Bosch Rexroth’s VPV Series

When we describe the VPKC as “fully compatible” with Rexroth’s VPV series, we mean it in the most practical sense: dimensional mounting compatibility, port configuration compatibility, and performance parity across the pressure and flow specifications that define the VPV product line. This is engineered specifically so that system integrators and OEMs currently working with VPV pumps can specify the VPKC as a direct alternative, without redesigning mounting brackets, re-plumbing port connections, or re-engineering control logic built around VPV performance characteristics.

Where the VPKC Fits

The VPKC Series is particularly well suited to:

• Industrial power units requiring variable flow output to match fluctuating downstream demand
• High-pressure clamping and pressing applications operating near the upper end of standard hydraulic pressure ranges
• Energy-conscious facility designs where reducing hydraulic system energy consumption is a stated operational priority
• OEM equipment currently specified with Bosch Rexroth VPV components, seeking a verified interchangeable alternative

Manufacturing Behind the Specification

Delivering genuine compatibility with an established, high-precision product line like Rexroth’s VPV series requires manufacturing capability that can consistently hold tight tolerances — not just on a prototype unit, but across full production volume. KCL’s investment in advanced, automated machining equipment (including precision grinding technology used throughout our facility) is what makes it possible to manufacture the VPKC to the dimensional and performance standards that genuine interchangeability requires.

Why Choose KCL’s VPKC Variable Vane Pump

Specifying a variable displacement pump is already a decision aimed at improving your system’s long-term efficiency. The VPKC Series lets you make that decision without also taking on compatibility risk — because it’s been engineered specifically to match the Rexroth VPV specifications your system may already be built around. Backed by KCL’s ISO 9001:2015 certified manufacturing and decades of hydraulic pump production experience, the VPKC gives you a dependable path to variable displacement performance at genuinely high-pressure ratings.
