Overview of xed displacement axial piston pump type K61N Fixed displacement axial piston pumps have a constant geometric displacement and convey a constant ow rate depending on the rotation speed. The axial piston pump type K61N is designed for open circuits in mobile hydraulics and operates on the bent axis principle. The pump is tted mainly to the power take-off on commercial vehicle transmissions. Features and benets: ■ ■ ■ ■ ■ Fixed displacement axial piston pump type K61N Optimised power-to-weight ratio Slim design Long lifetime Quiet operation over the complete speed range Low heat...

Choose a suction line which is as large as possible (also see nominal width selection Chapter 2, "Available versions, main data" in Table 6). Flexible hoses must be attached with two strong hose clamps. Do not use a screen on the suction side. Before the initial commissioning, all lines must be ushed with the uid provided for this purpose. The pump housing must be lled up at the upper drain port. NOTE Ensure cleanliness when lling! Before the rst start-up, check the rotation direction of the drive and pump. When starting up and during the rst few minutes, the main pressure-limiting valve...

Assembly, operation and maintenance recommendations 5.1 Intended use This product is intended exclusively for hydraulic applications (uid technology). The user must observe the safety measures and warnings in this documentation. Essential requirements for the product to function correctly and safely: – All information in this documentation must be observed. This applies in particular to all safety measures and warnings. – The product must only be assembled and put into operation by qualied personnel. – The product must only be operated within the specied technical parameters. The technical...

5.2.1 General information The K61N xed displacement axial piston pump is designed for use in an open or semi-closed circuit. It can be mounted on the usual mounting points (e.g. power take-off gearbox, combustion engine or electric drive, cardan shaft) using a ange mounting. A change of rotating direction is possible by turning the connection cover. For conversion instructions, please contact HAWE Hydraulik. During assembly, note the following principles: ■ ■ ■ Remove all plastic plugs before operation. Avoid installation above the tank (see Chapter 5.2.3, "Installation positions"). Before...

5.2.2 Connections The nominal width of the connecting lines depends on the specied operating conditions, the viscosity of the hydraulic uid, the start-up and operating temperatures and the rotation speed of the pump. In principle we recommend the use of hose lines due to the superior damping characteristics. Pressure connection The pressure connection for type K61N-012…064 is established via a threaded connection G 3/4 (BSPP), for type K61N-084…108 via a threaded connection G 1 (BSPP). Suction port The suction port on all pumps is established via standardised suction intakes with a size which...

5.2.3 Installation positions The K61N xed displacement axial piston pump can be mounted in any installation position. Horizontal installation: (pump below the min. ll level) ➯ For horizontal installation, use the uppermost drain port 5.2.4 Tank installation Tank installation (pump below the min. ll level) The pump can be operated either with or without a suction intake. It is recommended to use a short suction intake (see Chapter 6.1, "Accessories, spare parts and separate components").

5.3 Operating instructions Note product configuration and pressure / ow rate The statements and technical parameters in this documentation must be strictly observed. The instructions for the complete technical system must also always be followed. Read the documentation carefully before usage. The documentation must be accessible to the operating and maintenance staff at all times. Keep documentation up to date after every addition or update. Purity and ltering of the hydraulic uid Fine contamination can significantly impair the function of the hydraulic component. Contamination can cause irreparable...
