Product details
Manual swashplate adjustment changes displacement and therefore delivered flow at a given shaft speed. The rotating cylinder block and valve-plate interface use a hydrostatic balancing arrangement described in the product literature. This manually adjusted model should not be substituted for a pressure-compensated control without reviewing the hydraulic circuit.
The performance table also gives 94.5 L/min at 1,500 r/min at full displacement. These are theoretical displacement-based flows; actual delivery depends on operating pressure, oil condition and leakage. The source specifies N32–46 hydraulic oil, a 10–65°C oil temperature range and 15–20 micrometre return filtration, together with a separate case-drain arrangement.
SELECTION NOTES
Specify the operating duty
Provide pressure cycle, shaft speed, required adjustment range and hydraulic oil. Confirm rotation, shaft coupling, suction conditions, filtration and separate case-drain routing.
Published limits may describe different configurations within a series. Confirm that the required operating conditions are valid together.
