High-pressure gear motors KM

High-pressure gear motors KM with hydraulic axial clearance compensation

KRACHT KM external gear motors are suitable for deployment under the toughest operating conditions thanks to their design and the materials used. The main components are the housing and the flange cover. They can be dynamically highly loaded, making them insensitive to pressure peaks and continuous vibrations.
 

Characteristics

Displacement: 4.0 … 300 cm³/rev
Temperature range: -20 … 150 °C
Maximum pressure: … 315 bar

Applications

  • Mobile and stationary plants

  • Construction and agricultural machinery, municipal and special vehicles as a fan or other drive

Options

  • ATEX version

  • Motor-pump unit (hydraulically driven)

  • Outboard bearing to absorb radial and axial forces

  • As a drive in combination with a pump (KP or KF) e.g. for mobile liquid pumping

  • Various valve functions through modular design

  • Noise optimised version

Multiple motors

  • Up to six KM motors can be coupled
    (motor and flow divider)
