Variable Displacement Pump for Closed-Circuit Operation
With the new generation of swashplate pumps for closed hydraulic circuits, LHY Powertrain combines decades of experience from the 02 series with today’s diverse market requirements for closed-circuit pumps. Thanks to a modular design, it offers a wide range of options and globally standardized interfaces with minimal space requirements. Featuring a robust and proven rotating group from the 02 series and an optimized flow concept, the pump significantly reduces flow losses and noise emissions, achieving a very high level of efficiency compared to the market, without compromising durability. In terms of efficiency, the CPV includes, among other features, a new mounting concept that allows for the individual replacement of wear parts without the need to disassemble the pump.
