COMPANY PROFILE
Elmo Rietschle
The Elmo Rietschle brand of Gardner Denver resulted from the acquisition of the two renowned German vacuum and pressure companies still present in its name. With seven blower and compressor technologies, namely radial, claw, side channel, monoblock liquid ring, rotary vane, roots type and screw, we can support our customers in finding the best product for their applications. We serve both OEM and end customers in packaging, plastics, printing, chemical and pharmaceutical applications as well as in the food and beverage industry to name just a few. Elmo Rietschle is committed to the highest standards in quality, reliability and performance and serves customers on a global basis.

cost-efficient.
F-Series – Radial Blowers for Industrial Use
Elmo Rietschle offers a wide range of single- and multi-stage radial blowers for vacuum and pressure operation. Main applications for these radial blowers are packaging and paper handling. The smaller units with integrated dust separators can also be used for extracting small particles like paper dust or powders.
Advantages at a glance
- Cast housings and impeller
- Robust and economical
- "For life" greased bearings
- Quiet, low vibration
- Process safe and reliable
- Frequency control available
- Vacuum up to 115 mbar & pressure to 125 mbar
- Flows from 135 to 3400 m3/hr
G-Series – Side Channel Blowers Leading in Excellence
Some technologies are so good that it is hard to improve them. Side channel blowers from Elmo Rietschle are such an example. They have proven their reliability in service for many decades, performing flawlessly day in and day out with virtually no down time. Noise levels have been lower than that of most other vacuum pumps and compressors.
Side channel blowers are used for conveying gases and gas-air mixtures.
Advantages at a glance
- Reliable and built-to-last, virtually maintenance-free
- Robust yet light-weight
- For use worldwide (UL/CSA/IEC/EN approval)
- 50/60 Hz voltage range motors
- ATEX 94/9 EG
- Adjustable speed via external or integral converter
- Vacuum up to -800 mbar & pressure to +1000 mbar
- Flows from 16 to 1850 m3/hr
L-Series – Compact Liquid Ring Pumps for Heavy Duty
Extreme conditions, which prevail in humid and wet processes, lead to lime scale or abrasion, and hence to a considerable reduction in the performance of the pump. Elmo Rietschle liquid ring pumps, however, meet these challenges.
The use of high-quality materials such as stainless steel and ceramics ensure utmost reliability and constant operating characteristics – for years to come.
Advantages at a glance
- Constant operating characteristics by ceramic coating
- Minimized abrasion resistance
- Excellent corrosion resistance
- No deposits and lime scale
- Vacuum up to 33 mbar Abs & pressure to 2.6 bar
- Flows from 10 to 600 m3/hr
V-Series – Dry Running & Oil Lubricated Rotary Vane Pumps/Compressors
Elmo Rietschle offers dry running and oil lubricated rotary vane pumps covering a wide performance range.
The eco-friendly dry running rotary vane pumps are used for vacuum, pressure and combined pressure and vacuum applications. The time-tested oil lubricated rotary vane machines are typically used for generating vacuum.
Advantages at a glance
- Dry running and oil lubricated versions
- Low noise level
- Robust and economical
- Long up times
- Easy to operate
- Vacuum up to 0.1 mbar abs & pressure to 1.5 bar
- Flows from 4 to 1535 m3/hr
R-Series / Pedro Gil – Rotary Lobe Blowers: rugged and economical
These compact rotary lobe blowers belong to the group of dry running positive displacement pumps. This means that there is no need for oil or grease in the compression chamber. Only gear box and bearings, which are separated from the pumping chamber, are oil lubricated. Two non contacting triple lobed rotary lobe rotors rotate against each other in the compression room. The triple lobed rotors avoid pulsation problems. The blowers are customized to cater for the varying demands of our customers’ applications.
Advantages at a glance
- Robust and economical
- Dry running
- Modular design
- Available as single aggregates
- Available as individually engineered pump sets
- Frequency control available
- Vacuum up to 0.05 mbar abs
- Flows from 80 to 720 m3/hr
C-Series – Innovative Claw Technology
The C-Series claw pumps and compressors generate contact-free vacuum or compressed air efficiently and economically. This is possible because of the principle of internal compression. The gas is pre-compressed within the compressing chamber and is then discharged.
This leads to an evident energy saving compared to rotary lobe blower designs without internal compression.
Advantages at a glance
- Dry, contact-free operation
- Process safe and reliable
- No oil in the compression chamber
- Frequency control available
- Low sound level
- No greasing of bearings
- Vacuum up to 60 mbar abs & pressure to 2.2 bar
- Flows from 60 to 1200 m3/hr
S-Series – The Screw: rugged and durable
The S-VSA and S-VSB dry running, contact-free screw vacuum pumps are primarily used in the chemical and pharmaceutical industries for processing applications. A contamination with oil or other operating liquids is impossible. Several pump sizes are available with ATEX certification.
We have recently launched the new V-VSI screw vacuum pump – the first of its kind – for industrial applications such as packaging and drying.
Advantages at a glance
- Dry running
- High vacuum in one stage
- Application specific options
- Short evacuation time due to high suction capacities
- Flushing / CIP capable
- Insensitive against water shocks
- Vacuum up to 0.05 mbar abs
- Flows from 80 to 720 m3/hr
