Open the catalog to page 2Overview: variable displacement axial piston pump type V30E 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 V30E 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...

Open the catalog to page 72.8.1 Pressure controller P, Pb P-and Pb-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). The system pressure is tapped externally and signalled to port X2 to compensate any potential...
Open the catalog to page 82.8.2 Load-sensing controller LSP, LSPb The LSP and LSPb controllers are ow controllers that generate a variable, speed-independent ow rate. The controller adapts the displacement volume of the pump to the required ow rate of the consumer and regulates a constant difference between load pressure and pump pressure. Coding LSP Coding LSPb System pressure is tapped within the controller (internal). The system pressure is tapped externally and signalled to port X2 to compensate any potential pressure losses in the system.
Open the catalog to page 92.8.3 Power controller L, Lf, Lf1, Lfe L, Lf, Lf1, Lfe 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.

Open the catalog to page 112.8.5 Flow controller EM.CH 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). Associated auxiliary pump: V30E-09S: Z 02-6, V30E-160: Z 02-8, V30E-270: Z 02-11 The control system consists of the pump adjustment system, an NG 6 prop. directional valve and a swivel angle...
Open the catalog to page 12Coding EMPLCH NOTICE The adjustment times are approx. 200 ms. The EM.CH controller can be combined with pressure, LS and/or power controllers to limit pressure and/or power. NOTICE Additional, separately laid out overpressure protection (pressure-limiting valve) must be included in the hydraulics circuit in order to prevent pressure peaks. Ordering example Version without pressure limitation and power controller: V30E-160 Version with pressure and power controller: V30E-270
