General instructions
The A4VTG pump is designed to be used in a closed circuit. –
Project planning, assembly and commissioning of the axial piston unit require the involvement of qualified personnel. –
The service line ports and function ports are only designed to accommodate hydraulic lines. –
During and shortly after operation, there is a risk of burns on the axial piston unit and especially on the solenoids. Take appropri- –
ate safety measures (e. g. by wearing protective clothing).
Depending on the operational state of the axial piston unit (operating pressure, fluid temperature), the characteristic may shift. –
Pressure ports: –
The ports and fixing threads are designed for the specified maximum pressure. The machine or system manufacturer must
ensure that the connecting elements and lines correspond to the specified operating conditions (pressure, flow, hydraulic fluid,
temperature) with the necessary safety factors.
The data and notes contained herein must be adhered to. –
The following tightening torques apply: –
Threaded hole for axial piston unit: -
The maximum permissible tightening torques M
G max
are maximum values for the threaded holes and must not be exceeded.
For values, see the following table.
Fittings: -
Observe the manufacturer's instruction regarding the tightening torques of the used fittings.
Fixing screws: -
For fixing screws according to DIN 13, we recommend checking the tightening torque individually according to VDI 2230.
Locking screws: -
For the metal locking screws supplied with the axial piston unit, the required tightening torques of locking screws M
V
apply.
For values, see the following table.
The product is not approved as a component for the safety concept of a general machine according to DIN EN ISO 13849. –
