Linde is a manufacturer of axial piston pumps for open and closed circuits. The company’s offerings include variable and self regulating pumps. The products are suitable for a peak pressure of up to 500 bar in heavy duty hydraulic applications.
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.
