Overview: variable displacement axial piston pump type V80M Variable displacement axial piston pumps adjust the geometric output volume from maximum to zero. As a result they vary the ow rate that is provided to the consumers. The variable displacement axial piston pump type V80M is designed for open circuits in mobile hydraulics and operates according to the swash plate principle. It is available with the option of a thru-shaft for operating with additional hydraulic pumps in series. The sturdy pump is particularly suitable for continuous operation in challenging applications. The range...

2.9.1 Pressure controller P P-controllers are pressure controllers with xed pressure setting. As soon as the pump pressure exceeds the set value, the pressure controller reduces the swivel angle of the pump and adjusts the pressure level to a constant value. Depending on the controller type, the pressure is set either using an adjusting screw directly on the controller or using an external pilot valve on port X. Coding P System pressure is tapped within the controller (internal). 2.9.2 Load-sensing controller LSP The LSP controllers are ow controllers that generate a variable,...

2.9.3 Power controller L, Lf, Lf1, Lfe, Lfe1 L, Lf, Lf1, Lfe and Lfe1 controllers are power controllers whose characteristic curve is a perfect hyperbola. When the product of displacement volume times pressure exceeds the set value, the controller reduces the pump’s swivel angle. This protects the drive shaft, motor or gearbox from overloading (pB x Vg = constant). The power controllers are only available in combination with a pressure- or load-sensing controller.

Coding LfeLSP 2.9.4 Flow controller V, EM.CH V controller The V controller is an electro-proportional ow controller that generates a variable ow rate depending on the speed. The controller adjusts the pump’s displacement volume based on an electrical input signal. The resulting ow rate depends on the displacement volume and speed. The required pilot pressure for adjusting the swivel angle is tapped internally. An external auxiliary pump or a pre-load valve is required to ensure reliable switching. Coding VLSP

EM.CH controller The electro-hydraulic delivery ow controller EM.CH adjusts the displacement volume of the pump between "zero" and "maximum" in proportion to an electrical input signal, (target 0 - 10 V or 0 - 20 mA). The power for the adjustment is taken from the high-pressure line. System pressures under 50 bar will require an auxiliary pump in addition (thru-shaft). The control system consists of the pump adjustment system, an NG 6 prop. directional valve and a swivel angle pick-up (coding 2) for actual value determination. Control electronics (coding CH, type DAC-4) compare the...
