About us
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.

Our 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.

Our company represents quality, innovation and reliability. All up to 1000 bar.

Product Information
03.56.03 Pumps, compressor

03.56.05 Pumps, micro
Micro pumps 20.08.2008

Working in the high-pressure range, our micro pumps are suitable where compact design, light weight and high, consistent volumetric efficiency over the entire rotation speed and pressure range are required. Bieri products cover a pressure range from 200 to 700 bar and displacement from 0.02cc/rev. to 2.6 cc/rev. They are compact and totally reliable even in a very harsh environment. BIERI micro pumps are well adapted for oil exploration, downhole tools and portable pressing tools.
Using a modular design system, we offer a range of standard micro pumps and also special micro pumps to meet your individual requirements.

Operating pressure: up to 700 bar
Displacement: 0.016 up to 2.2 cm³/rev
Dimensions: ø 30mm to 61mm,
Length 60mm to 150mm
