Piston pumps

Two new sizes join the H1 piston-pump line — the 60 cm3/68 cm3 and 89 cm3/100 cm3. The new frame sizes target combines, telehandlers, forage harvesters, wheel loaders, concrete and asphalt pavers, road rollers and forestry machinery.

Electric-only control options include electrical displacement control (with mechanical feedback) for load-independent speed control; forward/ neutral/reverse for simple on/off work function control; and nonfeedback proportional electrical control for load-dependent control systems.

A high-response pressure limiter, designed to manage the engine load, limits system pressure by reducing the volume of oil that flows over the high pressure relief valve, resulting in less heat generated.

Control cut-off and control override options make it possible to perform a control-circuit integrity check during vehicle start-up, for a range of predefined operating scenarios.
