Product Description Linde Self Regulating Pump Repair
Linde Self Regulating Pump Repair
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.
Displacement size from 55 to 280 cc per unit
- Optimum interaction with Linde LSC control valves and LinTronic
- Dynamic response
- Noise optimization over the whole range of operation
- High power density
- Long working life
- Excellent suction up to rated speed
