H1P Axial Piston Single Pumps

The H1P Axial Piston Single Pumps series is a family of closed-circuit variable-displacement pumps built on a cradle swashplate design for hydrostatic power transmission. The series is available in a broad displacement range and uses an integral electro-hydraulic servo system to control swashplate position, which sets both output flow and flow direction. Across the series, the pumps support multiple control formats including electric, hydraulic, manual, automotive, fan-drive, and proportional control arrangements, with PLUS+1 compliant control and sensor options available for electronic machine integration. The design emphasizes high power density, compact packaging, standardized interfaces, improved charge-circuit efficiency, and installation flexibility through options such as auxiliary mounting pads and integral filtration. Overall, the H1P series is intended for mobile hydraulic systems that need controllable closed-circuit pump output, adaptable control architecture, and durable hydrostatic performance.
