Installation information
5.1 General information
The V60N variable displacement axial piston pump is designed for use in an open circuit.
It can be mounted directly on a truck power take-off (PTO) using a flange in accordance with ISO 7653-1985 or using a flange in
accordance with specifications.
Further connection options are available with a propshaft and suitable coupling sleeves (see Chapter 7, "Accessories, spare parts and
separate components")
A change of rotation direction is available for types V60N-060, V60N-090 and V60N-110 variable displacement axial piston pumps. For
conversion instructions, please contact HAWE Hydraulik SE.
The following essential points must be noted when installing the pump:
Mounting and removal of the pump and attached components may be performed by trained persons only. Ensure absolute cleanliness
during all work. Contamination may have an adverse effect on the function and service life of the pump.
■
Remove all plastic plugs prior to initial operation.
■
Avoid installing the motor above the tank (see Installation positions" inChapter 5.3, "Installation positions").
■
Observe the reference values in Section Chapter 7, "Accessories, spare parts and separate components" .
■
Prior to initial operation, fill the pump with oil and bleed. Automatic pump filling via the suction line by opening the drain ports is
not possible.
■
Prevent the pump and suction line from running dry.
■
Always ensure a constant supply of oil. Even a brief shortage in the supply of hydraulic fluid to the pump may damage internal parts.
This may not be immediately evident after initial operation.
■
The hydraulic oil returning to the tank from the system must not be sucked back in immediately (baffles).
■
Run the pump for approx. 10 minutes at max. 50 bar after initial operation.
■
Thorough bleeding/flushing of the entire system is recommended before the full pressure range is used.
■
Observe the max. permissible operating range temperatures (see Chapter 3, "Parameters") at all times.
■
Always comply with the specified oil purity classes (see Chapter 3, "Parameters"); provide appropriate hydraulic fluid filtering.
■
Use of a filter in the intake line must be approved by HAWE Hydraulik.
■
Include a main pressure-limiting valve in the pressure line to limit the max. system pressure.
