4 1 Overview of variable displacement axial piston pump type V60N Thanks to its sturdy construction, the variable displacement axial piston pump is designed for direct flange mounting to the power take-off on commercial vehicle gearboxes, or for standard connection using an SAE flange. The benchmark figures for this product are 130 cm3/rev and 450 bar end pressure, allowing for a wide range of applications. These are supported by a high self-suction speed rating and low noise level. Variations with thru-shaft for flange mounting additional variable displacement axial piston pumps and auxiliary pumps are also available. Several different controllers offer the user a wide range of application possibilities. Particular advantages with regard to the mutual coordination arise from a combined application of variable displacement axial piston pumps with proportional directional spool valves type PSV and possibly required load-holding valves type LHT and LHDV. Image 1: Variable displacement axial piston pump type V60N-110 Features and benefits: Good performance/weight ratio High self-suction speed Different shaft and flange versions Intended applications: Machines for forestry and agricultural purposes Cranes and lifting equipment Truck-mounted concrete pumps Municipal trucks Image 2: Variable displacement axial piston pump type V60N D 7960 N

36 5 Installation information for variable displacement axial piston pump V60N General information The V60N is designed for use in an open circuit. It can be fitted directly on a truck power take-off (PTO) using a flange in accordance with ISO 7653, ISO or with an SAE-C, SAE-B2, SAE-B4 ISO or SAE-C 4-Hole. Further connection options are available with a propshaft and suitable coupling sleeves. Rotation direction changing is available for all V60N pumps. 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 pump above the tank (see Installation positions in Chapter 5, "Installation information for variable displacement axial piston pump V60N"). Observe the reference values in Chapter 7.2, "Suction intakes" lines. 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 start-up. 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 start-up. 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. Ensure compliance 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 D 7960 N

37 Ports The nominal width of the connecting lines depends on the specified operating conditions, the viscosity of the hydraulic fluid, the start-up and operating temperatures and the speed of the pump. In principle we recommend the use of hose lines due to the superior damping characteristics. Pressure port The pressure port is established in type V60N-060via a a G 3/4 threaded connection and in type V60N-090/110/130 via a G 1 threaded connection. Observe the torque specification of the part manufacturer. Suction port The suction port is established in all pumpsvia standardised suction intakes of an appropriate size for the max. delivery flow of the pump. The specification of the max. delivery flow Q max must be observed. This can be found in the following table. Nominal width (N) 38 (1 1/2 ) (2 ) 64 (2 1/2 ) 74 (3 ) 6 (G 1 1/4) 7 (G 1 1/2) Q max (l/min) The suction intakes can be ordered as an option with the pump. If possible, route the suction line to the tank in such a way that it is steadily rising. This allows trapped air to escape. Observe the specifications in Chapter 5, "Installation information for variable displacement axial piston pump V60N" under Installation positions. The absolute intake pressure must not fall below 0.85 bar. A hose line should generally be used in preference to a rigid pipe. Drain port The V60N pumps have 2 drain ports of G 3/4 or 1 1/16-12-UN-2B. A G 1/8 threaded connection is also available for flange versions SAE-B2, SAE-B4 and SAE-C. This is used for bleeding in the case of vertical installation positions. The nominal width of the overflow oil line must not be less than 16 mm. The cross-section is determined by the max. permissible housing pressure. Integrate the overflow oil line in the system in such a way as to prevent direct connection with the intake line of the pump. Both drain ports can be used simultaneously. A separate overflow oil line from the controller to the tank is not required. Observe the specifications in the Installation positions section. LS port for version (LSNR/LSN) The LS line is connected to the controller via a G1/4 threaded connection. The nominal width of the line depends on the installation position of the pump and should hold 10% of the pressure line capacity. A hose line should generally be used in preference to a rigid pipe. When the proportional directional spool valve is in a neutral position, the LS line must be fully released! D 7960 N 37

38 Installation positions The V60N can be installed in any installation position. Observe the truck manufacturer s specifications if installing the pump directly on a truck power take-off. A support is required for tandem pumps or two hydraulic pumps mounted in series. The following points must be observed: Horizontal installation: (pump below the min. hydraulic oil level) For horizontal installation, use the uppermost drain port. Vertical installation: (pump below the min. hydraulic oil level) Mount the pump so that the pump mounting flange is facing upwards. Only pumps with mounting flanges of type SAE-B2, SAE-B and SAE-C are approved for vertical installation. For vertical installation, use the uppermost drain port. Also connect the G 1/4 bleeding port on the pump flange. Take appropriate measures to ensure continuous bleeding of this line (line routing/bleeding).

39 Tank installation (pump below the min. hydraulic oil level) The pump can be operated either with or without a suction tube. Use of a short suction intake is recommended; see Section 4.3, Table 3. Additional notes regarding installation above the tank fluid level Special measures are required if the pump is installed above the tank fluid level. The pump must not run dry via the pressure, intake, drain/bleed or control lines. This applies in particular to long periods of downtime. A check valve (opening pressure approx. 0.5 to 0.6 bar) in the overflow oil line can prevent the pump housing from being emptied. Facilitate bleeding of connecting lines via separate bleed openings. Adjust the bleeding sequence to the specific installation. For specialist guidance, use the form B 7960 Axial piston pump checklist. Further information on installation, operation and maintenance can be found in the relevant operating instructions B 7960 N, B D 7960 N 39

40 6 Installation, operation and maintenance information 6.1 Designated use This fluid-power product has been designed, manufactured and tested using standards and regulations generally applicable in the European Union and left the plant in a safe and fault-free condition. To maintain this condition and ensure safe operation, operators must observe the information and warnings in this documentation. This fluid-power product must be installed and integrated in a hydraulic system by a qualified specialist who is familiar with and adheres to general engineering principles and relevant applicable regulations and standards. In addition, application-specific features of the system or installation location must be taken into account if relevant. This product may only be used as a pump within oil-hydraulic systems. The product must be operated within the specified technical parameters. This documentation contains the technical parameters for various product versions. Note Non-compliance will void any warranty claims made against HAWE Hydraulik. 6.2 Installation information The hydraulic system must be integrated in the equipment with standard connection components that comply with market requirements (screw fittings, hoses, pipes, etc.). The hydraulic system must be shut down as a precautionary measure prior to dismounting; this applies in particular to systems with hydrostatic accumulators. 6.3 Operating instructions Product, pressure and/or flow settings Generally, the manufacturer sets the product. If the customer is setting the product, the information in this documentation must be observed in full. Filtering and purity of the hydraulic fluid Fine contamination (e.g. grit and dust) or contamination in the macro range (e.g. filings, rubber particles from hoses and seals) can significantly impair the function of a hydraulic system. It should also be noted that new hydraulic fluid straight from the container does not necessarily meet the highest purity standards. Attention must therefore be paid to the purity of the hydraulic fluid (see also Purity class in Chapter 3, "Parameters"). Maintenance information Further information on installation, operation and maintenance can be found in the relevant operating instructions B 7960 N, B D 7960 N

The pressure controller automatically maintains a constant system pressure independently of the required delivery flow. Therefore it is suited to constant pressure systems where differing delivery flows are required or for efficient pressure limitation of the hydraulic system.
