Linde HPR-2 Manual page 2

Design characteristics
>> high pressure axial piston pump in swash plate design for open loop systems
>> clockwise or counter clockwise rotation
>> self-priming at high nominal speed
>> higher rotating speed by tank pressurization or swash angle reduction
>> adaptive noise optimization SPU
>> decompression fluid is drained via pump housing for suction side stability
>>
exact and rugged load sensing controls
>> SAE high pressure ports
>> SAE mounting flange with ANSI or SAE spline shaft
>> through shaft SAE A, B, B-B, C, D and E
>> optional tandem and multiple pumps
Product advantages
>> energy saving operation by "flow on demand" control
>> dynamic response
>> excellent suction up to rated speed
>> noise optimization over the entire range of operation
>> optimal interaction with Linde LSC-directional control valves and LinTronic
>> compact design
>> high power density
>>
high pressure rating
>> high reliability
>> long working life
