Advantages of Bieri pumps
News
September 2012
Dear Hydac Colleagues
Welcome to the second issue of our Bieri newsletter, which gives you a more detailed look at
our assortment of pumps. Together with valves, pumps form part of our standard product
portfolio. We deal in high-pressure hydraulics, so all of our pumps are of course specially
designed to handle pressures in excess of 500 bar. Our highly diverse selection of pumps
covers a very broad range of displacement and pressure configurations.
The newsletter explains their main features and advantages. You can find out more on our
website at www.bierihydraulics.com/en/standard-components/pumps.html.
Please don’t hesitate to ask us if you can’t find what you’re looking for – we can offer a
solution to suit virtually any technical demands! We also would like to draw your attention to
our special micro pumps, which are proofed under strongest conditions.
Best regards
The Bieri Team
Advantages of Bieri pumps
 Very long economic lifetime
 Very good suction
performance:
- due to the longer
piston stroke (8 mm)
- due to low piston
clearance
 Very good volumetric
efficiency
 No venting required on
run up
 Continuous pressure of
700 bar for all pumps, as
much as 1,000 bar for some

 All pumps are self-venting
 Small and compact design
 Suitable for use with mineral
oil or fluids such as HFD
with a viscosity of 2 mm²/s
or higher
