Sauer-Danfoss now offers 60/68 cm³ (3.7/4.1 in³) and 89/100 cm³ (5.4/6.1 in³) H1 piston pump frame sizes. The H1 lineup includes six displacement ranges with the latest frame sizes offering additional flexibility for improved vehicle efficiency and productivity on combines, telehandlers, forage harvesters, wheel loaders, concrete and asphalt pavers, road rollers, and forestry machinery. Features include high power density, compact size, and lighter weight for design flexibility. H1 pumps share a common electronic control platform and feature electrical displacement control with mechanical feedback for load-independent speed control; forward/neutral/reverse for on/off work function control; and non-feedback proportional electrical control for load-dependant control systems. Pumps can interface with the company's microcontrollers, and an optional pressure limiter reduces the volume of oil that flows over the high pressure relief valve, reducing the need for cooling.
