Bosch Rexroth Axial piston variable pump A7VO Series 63 Injection
molding machine, hydraulic press,
Characteristics
– Variable displacement axial piston elements with tapered piston
rotor group in helical design for open circuit hydraulic drives
– For mobile machine operation and industrial applications
– The flow rate of the hydraulic pump is proportional to the speed
and displacement of the pump and varies infinitely from qv max to
qv min = 0
– Wide control range and adjustment device
– Compact, robust bearing system with long service life
– Long-life bearings available for special oils and extremely long
service life requirements
– Pressure control as standard

Safety information
- The A7VO(LO) pumps are designed for operation in open circuits
- System design, installation and commissioning must be carried out
by trained technicians or dealers.
- All hydraulic ports may only be used to install hydraulic working
lines.
- The housing (especially the solenoid) may be very hot during and
shortly after operation of the pump, so burns must be avoided; take
appropriate safety precautions (wear protective clothing).
- Depending on the operating conditions (operating pressure, oil
temperature) of the axial piston element, deviations in the
performance curves may occur.
- Pressure ports:
All materials selected and port threads designed to withstand peak
pressures.
Machine and system manufacturers must ensure that the safety
factors of all connecting elements and hydraulic lines are suitable
for the actual operating conditions (pressure, flow, oil,
temperature).
- All data and information provided with the product must be
observed.
- The product is not certified as a component in accordance with
the requirements of the safety concept of the entire machine system
in accordance with DIN EN ISO 13849.
- The following tightening torques apply:
• Threaded holes in the axial piston unit:
The maximum permissible tightening torque MGMax is the maximum
value for the threaded holes in the pump housing and must not be
exceeded. The values are given in the table below.
• Accessories:
Observe the manufacturer's information on the maximum permissible
tightening torques for the accessories used.
• Fastening screws:
For fastening screws in accordance with DIN 13, we recommend that
you check the permissible tightening torques in the individual case
in accordance with VDI 2230.
• Locking screws:
For the locking screws supplied with the axial piston unit, the
following required minimum tightening torques MV should be applied.
