Sauer-Danfoss Pumps Offers Versatility for Mobile Machinery

Lincolnshire, Ill.-based Sauer-Danfoss has announced the release of its new H1 115/130cc pump, joining the company's line of H1 pumps. The H1 pump family was introduced in 2005, and continued to grow through 2007 with the H1 45/53cc single pump and the 78cc single pump. The release demonstrates Sauer-Danfoss' continued commitment to fill the demand for electric-actuated pumps that maximize hydraulic system efficiency and add value to machine operating performance across a broad field of mobile machinery.

The H1 family of closed-circuit variable displacement axial piston pumps is compact and features high power density, resulting in ease of installation and increased design flexibility. All the units utilize an integral electro-hydraulic servo piston assembly that controls rate and direction of hydraulic flow. H1 pumps can be used with other Sauer-Danfoss pumps and motors in the hydraulic system.

“This new generation of H1 pumps will be a popular size for many hydrostatic applications,” said Randy Rodgers, Sauer-Danfoss product portfolio manager. “The H1 family of pumps offers the OEM a number of advantages including an increased selection of displacement and product design life, and opportunities to improve vehicle maintenance and operating costs.”

“The interface of the electric hydraulic control is the future of mobile machinery,” added Rodgers. “The H1 pumps are built to support next generation engines as the industry moves toward Tier 4 emission controls. They are fully PLUS+1 Compliant to interface seamlessly with Sauer-Danfoss' electronic machine control architecture. H1 pumps offer the right displacement, right load life and the right value for the OEM's machine investment.”

The H1 family is designed for high and medium power mobile machinery that demands steady, instant propulsion and precise control. “H1 pumps are designed for smaller package sizes with a significant reduction in the length of the units, giving design engineers more freedom and flexibility in design,” said Rodgers.

H1 hydraulic systems maximize power and conserve energy for complex applications with high productivity demands for many off-highway industries, including agriculture, construction, road building, material handling, forestry and turf care. H1 complements complete systems for telehandlers, crawlers, skid steer loaders and more.
