Power Units

D.C. Electro-pumps, series ET

The essential components of series ET electro pumps are an external gear pump and a D.C. motor.

The 12 and 24 VDC motors feature high efficiencies and precision-balanced rotors for low-vibration running. They are combined with our AP05 - AP100 external gear-pumps to produce the ET series of electro-pumps, a family of products that are notable for their low noise levels in operation.

Simplicity of construction and reduction in size are the fundamental objectives in the design of the ET electro-pumps.

Advantages

  • Low noise emission
  • Wide range of displacements and electric motor powers

Hydraulic power packs, series UP

These units feature a high degree of accuracy and have a wide application range. Bucher Hydraulics power packs are designed according an integrated modular system of valves for the various functions.

This highlights the equipment’s compact nature, the foundation of its high performance level.

The basic components of the power packs are:

  • a manifold block with cavities for various types of valves
  • a very quiet, high-efficiency gear pump
  • an electric motor (DC or AC)
  • a reservoir (plastic or steel)
  • several optional accessories

Advantages

  • Compact and modular construction, limited number of components, quick and easy assembly
  • Maximum flexibility – numerous different circuits can be built from just the few basic versions
  • Valve cavities conform to international standards
  • Optimisation of motor-pump unit produce increased efficiency and low operating noise level
