Application
Rexroth A6V/A7V series Widely used in a variety of engineering machinery, plastic machinery, metallurgical machinery, pressing machinery and other large machinery.
Safety Information
The pump A7VO was designed for operation in open loop circuits
Systems design, installation and commissioning requires trained technicians or tradesmen.
All hydraulic ports can only be used for the fastening of hydraulic service lines.
During and shortly after operation of a pump the housing and especially a solenoid can be extremely hot, avoid being burned; take suitable safety measures (wear protective clothing).
Dependent on the operating conditions of the axial piston pump (operating pressure, fluid temperature) deviations in the perfor- mance curves can occur.
Pressure ports:
All materials and port threads are selected and designed in such a manner, that they can withstand the peak pressures.
The machine and system manufacturer must ensure, that all connecting elements and hydraulic lines are suitable for the actual operating conditions (pressures, flow, fluid, temperature) in accordance with the necessary safety factors.
All given data and information must be adhered to..
The product has not been released as a component in the safety concept of a total machine system acc. to DIN EN ISO 13849.
The following tightening torques are valid:
Female threads in the axial piston unit:
the maximum permissible tightening torques MGMax are maximum values for the female threads in the pump casting and may not be exceeded. For values see table below. -
Fittings:
please comply with the manufacturer‘s information regarding the max. permissible tightening torques for the used fittings.
Fastening bolts:
for fastening bolts to DIN 13 we recommend to check the permissible tightening torques in each individual case to VDI 2230.
Plugs:
for the metal plugs, supplied with the axial piston unit the following min. required tightening torques MV apply (see table)
