Overview: variable displacement axial piston pump type V30D 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 axial piston pump type V30D is designed for open circuits in industrial hydraulics and operate according to the swash plate principle. They are available with the option of a thru-shaft for operating additional hydraulic pumps in series. The sturdy pump is particularly suitable for continuous operation in challenging applications. The range of pump controllers...

2.2.1 Controller LS, LSN, LSP, LSD The LS(N,P,D) controller is a delivery ow controller that generates a variable ow rate independently of the speed. It adapts the geometric displacement of the pump to the required ow rate of the consumer and regulates a constant difference between load pressure and pump pressure. ■ ■ ■ ■ LS: Without pressure limitation LSN: With integrated pressure limitation LSP: With remote-control port for external pressure limitation LSD: Without pressure limitation for parallel operation of several pumps The LSD controller is used if several pumps supply the same...

Pressure adjustment Pressure range (bar) Factory-set pressure setting (bar) Maximum pressure pmax (N250)1) Maximum pressure pmax (N400) Pressure adjustment 1) Depending on the pressure setting, either a weak spring (N250) or a strong spring (N400) is installed. CAUTION Risk of injury on overloading components due to incorrect pressure settings! Risk of minor injury. ■ Always monitor the pressure gauge when setting and changing the pressure. NOTE Loosen the lock nut sufficiently before setting so that the sealing ring is not damaged.
