The HPR Linde replacement by “tech Hydro” is an advanced axial piston swash-plate pump designed for open-loop applications, featuring variable volume displacement and load-sensing control for energy efficiency. It self-primes efficiently, has excellent suction capacity, and its speed can be enhanced through tank pressurization or adjusting the swash angle. Optimally integrated with Linde directional control valves and the LINTRONIC electronic control unit, it minimizes noise with a silencer that reduces pressure peaks. The pump’s compact, high-density design ensures superior quality, reliability, and fast response, making it suitable for both mobile and stationary applications.

The designed pump features a maximum swash angle of 21°, allowing for both clockwise and anti-clockwise rotation, coupled with various load sensing control methods for versatile operation. Enhanced service life is achieved through the use of plain bearings supporting the cradle, which also reduces noise and improves control response. The pump incorporates high safety factors, robust precision regulating mechanisms, and external venting of decompression fluid for stability on the suction side. A single piece housing is used to eliminate leakage and enhance rigidity, while hydrostatic compensation manages axial forces, and SAE high-pressure connections allow operation at up to 6000 psi.

The specifications you’ve provided outline a range of tandem pumps with varying sizes, including 55, 75, 105, 135, and 210 cm³/rev, along with the option for multiple pump configurations, particularly featuring two 105 cm³/rev pumps. This flexibility likely allows for tailored solutions in fluid power applications, accommodating different flow rate requirements and system configurations for optimal performance.
