Bieri Logo

     Bieri Hydraulik AG with its staff of Swiss professionals has more than 50 years experience in the development, manufacture and sales of quality hydraulics extending from standard high pressure components to special solutions - covering all pressure ranges up to 1000 bar. Bieri provides a complete range of high pressure hydraulic components including pumps (axial and radial piston pumps, single or multiple outlets), seated valves (manually or solenoid operated), pressure valves (pressure relief valves, unloading valves, pressure reducing valves, load holding and lowering valves), flow control valves (orifice plates, throttle valves), non-return valves (shut-off valves, pilot operated check valves), manual gate valves, pressure switches, oil level switches for flows up to 12l/min or 25l/min. Their standard components and special solutions are used in mechanical engineering, oil, shipbuilding, medical technology, power stations and high-voltage circuit breakers, mining, defense, public transport, paper, food, construction, and in many other areas of industry. All products are available through a worldwide network of distributors. Bieri also delivers complete solutions and systems for any kind of hydraulic use and pressure range. Bieri represents quality, innovation and reliability. All up to 1000 bar.

Pumps
 
Pump Info

   Bieri offers many types of pumps such as axial piston pumps, radial piston pumps, combination pumps (combines a radial high pressure piston pump and a gear pump if two hydraulic circuits with different delivery volumes and pressure are required), multi-outlet pumps and explosion protected pumps. Bieri pumps are suitable for a wide pressure range and displacement.
