Introduction
Elmo Rietschle is a new brand name within the Gardner Denver
Group and was formed by merging the products of Elmo (formerly
Siemens Elmo) and Rietschle. Both of these are long established
German vacuum pump and blower manufacturers.
The two companies
Gardner Denver Deutschland GmbH
and
Gardner Denver Schopfheim GmbH
design, build and sell, under the roof of Gardner
Denver, pumps and compressors as the new
Elmo Rietschle
brand which was born from two renowned names
in the industry: Elmo (formerly Siemens) and
Rietschle.

Functional principle of a liquid ring pump
• Eccentric position of the impeller within the casing
• The rotation of the impeller generate a rotating liquid ring
• Variable compression chambers between the impeller blades
during the rotation.
• The conveyed gas will be compressed within a full revolution

One common question is….
Why does it need a 2 stage VWZ to reach 0.5 mbarA when
a single stage VC pump will do the same?
The answer is simple, a VC pump has large quantities of oil
circulating and has non-return valves. This allows high
vacuum in a single stage.
A “Once Through Oil” (OTO) pump uses only a small
quantity of oil and has no non-return valves.
Booster Groups
VPA
The VPA is a VWZ with a roots type
booster.
Capacities
485 to 4000 m3/hr (50 Hz)

Although not in the catalogue, boosters
can be fitted to the VLV.
Once Through Oil Lubricated Rotary Vane Vacuum Pumps
Advantages
Disadvantages
Relatively low cost
Small amounts of oil in exhaust
High efficiency
Liquid ingress can cause failure
High levels of vacuum
Oil reaction with certain processes can
cause problems
Corrosive vapour handling
with standard materials
High solvent load can wash off oil.
Simple to maintain, can be
restored to “as new”
performance.
Running for long periods at rough
vacuum (above 100 mbarA) can blow
off the oil.( not VL or VLB)

Almost every country in the world has some industry
that uses process vacuum pumps.
Investment is moving towards Asia.
If we work together we can benefit from the shift in
investment.
The Zephyr range has been expanded
and improved, developments are
continuing
This presentation gives information on the new models
and comparisons with some competitors products.
Applications for Zephyrs, vacuum and pressure, are
shown.
The Zephyr uses rotary claw technology to develop
vacuum and pressure.
Its dry running, wear free, pumping action is extremely
efficient and it requires very little maintenance.
KLR
