Sauer PV23 Pump

The Sauer PV23 hydraulic pump is an axial piston pump with variable output for closed systems. The maximum pump flow is 89 l/min (cm³/rev). It is a pump with the right rotation direction of the drive shaft and mechanical control of the pump output, which has the performance of low noise, high speed, and high pressure, and is mainly used in the concrete pump truck and mixer industry.

Sauer MF23 Motor

The Sauer MF23 hydraulic motor is mainly used in the concrete mixer truck, Its main features are a pass-axis piston pump, hydrostatic transmission, and manual servo-hydraulic variable control.
