Danfoss develops smart pump for off-highway applications
Danfoss says its new piston pump offers high performance hydraulics
Danfoss has completed its H1 range of sophisticated, high-power drives. The new 210/250cm3 piston pump closes offers versatility and high performance for off-highway machine applications, according to the firm. With these additions, the comprehensive range comprises 14 pumps with displacements covering 45-250cm3, five bent axis motors spanning 60-250cm3 and five control options. This offers solutions for advanced transmission solutions.
According to Danfoss, efficiency compensates for low engine rpm. Featuring a compact, lightweight design, the H1 pumps and motors afford versatility and high operating efficiency compensates for the lower rpm of emissions-compliant engines, with the motors outperforming rival units by up to 6%.
A patented integrated speed limitation (ISL) circuit adds to the high-level pump functionality, enabling improved vehicle braking with no risk of engine overspeeding. Danfoss has paid attention to the SIL 2 functional safety requirements that, along with Tier 4, are driving the trend towards intelligent machine management. Enabling automatic adjustment of vehicle driving characteristics to on or off-highway conditions, H1 Automotive Control (AC) is pre-SIL 2 certified.
Most recently, Danfoss has supplemented H1 AC with Eco Mode and Cruise Control options. Configured to lower engine rpm during on-highway transport, Eco Mode cuts fuel consumption by up to 20%. The entire H1 family is compatible with the Danfoss plus+1 control platform, including pre-tested software blocks that save on system development time, bringing new applications faster to market.
