ELMO RIETCHLE VACUUM PUMPS

Airmac offer an outstanding choice of dry running and oil lubricated rotary vane vacuum pumps and compressors, screw vacuum pumps as well as liquid ring, rotary lobe and claw vacuum pumps and compressors.

Elmo Rietschle 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.

Elmo Rietschle R Series 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 gearbox 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

Elmo Rietschle C Series Innovative Claw Technology

The C-Series claw pumps and compressors of Elmo Rietschle 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

Elmo Rietschle S Series dry running and low maintenance screw vacuum pump

The S-VSI screw vacuum pump (sizes 100 and 300) represents modern, state-of-the-art dry running technology that excels when it comes to small carbon footprint and low life cycle costs. It is used in a variety of industrial applications such as drying and packaging. Click here to find out more.

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.

 

Advantages at a glance

  • Dry running

  • High vacuum in one stage

  • Application specific options

  • Short evacuation time due to high suction capacities

  • Insensitive against water shocks
