Hydraulic piston pump HPR-02

Legal emission regulations force manufacturers of mobile machinery to optimize the noise emission of their products. Since secondary measures tend to be expensive and less efficient Linde Hydraulics prefers to fight the noise where it is generated: by optimally connecting an additional volume directly next to the commutation of the HPR-02 pump, Linde Hydraulics invented the SPU silencer. The adaptive SPU reduces pressure pulsations in the regulating pump over the entire range of operation – without loss of power. Advantages optimum interaction with Linde LSC control valves and LinTronic energy saving operation by ‘flow on demand’-control dynamic response excellent suction up to rated speed noise optimization over the whole range of operation high reliability long working life Design characteristics axial piston pump in swashplate design for high pressure open loop systems clockwise or counter clockwise rotation self-priming at high nominal speed tank pressuhzation or swash angle reduction for high speed applications adaptive noise optimization SPU decompression fluid is discharged via pump housing to keep suction side calm exact and rugged load sensing controllers with or without swash plate position feedback
