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.

Advantages at a glance:

Constant operating characteristics by ceramic coating

Maximum abrasion resistance

Excellent corrosion resistance

No deposits and lime scale

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
