MDP 5011
If you need:
• to replace a rotary vane pump
with a dry pump for an application
at 10-3 mbar
• a turbopump that can
operate up to 10 mbar
• a pump that can flow
up to 400 SCCM
There is a pump that has been
designed to operate efficiently under
these conditions: the MDP 5011.

• High-quality freeze drying
• Spectrometry
• Production of light bulbs
• Production of electronic tubes
The MDP offers high pumping performance between 10 mbar
and 10-5 mbar and a maximum flow rate of 400 sccm.
With an exhaust pressure up to 40 mbar, the MDP
can allow the use of a less expensive backing pump.
With its simple construction, robust rotor and low rotational speed
(27.000 rpm), the MDP is robust against accidental air in-rush,
shock venting and gyroscopic effects.
The MDP 5011 is field maintainable providing lower cost of
ownership and increased uptime.

Ceramic bearings
Alcatel has chosen high technology ceramic ball bearings for the MDP 5011
that are lightweight with a low coefficient of friction. These bearings provide Key Points
high reliability due to low centrifugal forces on the bearing cage and reduced • Ultimate pressure

• Light and compact
• High compression ratio
• High exhaust pressure

• Mountable in any position
The MDP design principle • High throughput
The Holweck principle is the basis of
the MDP design. This design positions
the pump performance between
Roots-type pumps and turbomolecular
pumps.
This high technology pump includes
3 different stages: Inlet
