Axial Piston Pumps & Motors
There are Open and Closed circuit types of pumps and motors.
Open circuit axial piston pumps
Open circuit axial piston pumps are used to operate services (hydraulic motors and cylinders) on mobile agricultural and construction machinery, also for lifting and for cleaning applications
Open circuit pumps are available with various control logic options: hydraulic load sensing, electronic load sensing, constant pressure, and for certain applications, constant power. All pumps can be equipped with pressure sensors and with swash plate angle sensors. An extensive product range affords the facility of assembling multiple units with axial piston pumps of different sizes, and with gear pumps.\
Closed circuit axial piston pumps
Closed circuit axial piston pumps are used as hydrostatic transmission components in self-propelled machines and for rotary drives in both fixed and mobile equipment of all kinds.
Variable displacement axial piston pumps for closed circuit applications are available with a variety of control options: direct manual, servo-assisted manual, remote hydraulic, remote hydraulic with feedback, On-Off electric in closed centre and open centre configurations, proportional electric and hydraulic automotive. Electronic control logic options include automotive, constant speed drive, shift-on-the-fly and feedback. Multiple units can be assembled using axial piston pumps of different sizes, and gear pumps. Possible configurations include circuits with built-in exchange valves and pressure relief valves.
Fixed-displacement axial piston motors
Closed circuit axial piston motors are used as hydro static transmission components, in conjunction with closed circuit pumps, and foundconsequently in the widest imaginable range of mobile equipment. Fixed displacement motors can also be used in open circuit applications, and are therefore suitable for a variety of hydraulic circuits, such as those of hoists and fan drives
Axial piston motors can be fixed or variable displacement. Variable displacement motors are available with two position hydraulic controls, two position electric control and proportional electric control. Controls can also be customised where particular strategies are required. Possible configurations include circuits with built-in exchange valves and pressure relief valves. Built-in cartridge versions also available for epicyclic hubs.
