Model description

Technical parameter

Working pressure range

A or B port pressure: rated pressure Pn = 35MPa, the highest pressure Pmax = 40MPa

The sum of the pressure of the A and B ports shall not exceed 63 MPa, and the pressure of the oil port on each side shall be up to 40 MPa.

Drain pressure:

Allow T port maximum drain pressure

Pate=0.2MPa

Temperature oil temperature range

t _min = -25℃      t _max = +80℃

Viscosity range

V_max= 10mm²/s

t_max= (短时)1000mm²/s

Optimum working viscosity

V_opt：16~36mm²/S

Hydraulic oil selection: Flllid Recommendation

Orking temperaure:recommended viscosity.Level match:DIN51519

Hydraulic oil filtration

The recommended filtration accuracy is 10μm, and 25-40μm can also be used, but using 10μm can prolong the service life (reduced wear).

Range of speed

There is no limit on the minimum speed. When a very uniform speed is required, nmin is not less than 50r/min.

The maximum speed is determined by the maximum flow from the pump and the minimum displacement of the variable motor. The minimum displacement is limited by an adjustment screw, so the variable motor does not overspeed.

The maximum allowable speed reference is in the technical data sheet
