Side Channel Blowers and Vacuum Pumps

Some technologies are so good that it is hard to improve them. The Elmo Rietschle Side channel blowers are such an example. Performing flawlessly day in and day out with virtually no downtime, the G-Series has a proven history of outstanding reliability over many decades of service. We offer side channel blowers in a wide variety of performance ranges to cover the most varied requirements, up to 3,000 m³/h and differential pressures of up to 1,000 mbar. The G-Series side channel blowers the ideal solution for worldwide use; they can be used without modifications or tests in Europe, Asia and America. This includes voltage range motors for 50 and 60 Hz in protection class IP 55 (insulation class F) and are UL 1450 and CAN/CSA C22.2 No. 68-09 approved.

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

Liquid Ring

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.

Constant operating characteristics by ceramic coating
Maximum abrasion resistance
Excellent corrosion resistance
■ No deposits and lime scale

Dry Running and Oil Lubricated Rotary Vane Vacuum Pumps and Compressors

Our industry leading dry running and oil lubricated rotary vane pumps cater for a wide performance range. The eco-friendly dry running rotary vane pumps are used for industrial vacuum, pressure and combined pressure and vacuum applications. Whilst, the time-tested oil lubricated rotary vane machines are typically used for generating vacuum.


Dry running and oil lubricated versions
Low noise level
Robust and economical
■ Long up times
■ Easy to operate and maintain
■ Low oil consumption on oil lubricated machine

Rotary Lobe Blowers

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.

■ Available as single aggregates
■ Available as individually engineered pump sets
■ Frequency control available

Claw Vacuum Pumps And Compressors

The C-Series dry claw vacuum pumps and claw air compressors of Elmo Rietschle generate contact-free vacuum or compressed air efficiently and economically. This is possible because of the principle of internal compression in the rotary claw design. The gas is pre-compressed within the compressing chamber and is then discharged. 
The Elmo Rietschle dry claw pumps offer significant energy saving and high efficiency compared to the traditional rotary lobe blower designs without internal compression. 

The innovative claw technology 

The claws of the C-Series feature an optimized, high precision shape and roll together without contact, synchronised by a precision gear set. The compression is achieved dry and wear free. Special seals separate the compression chamber and gearbox. The claw rotors control the transportation of the medium by opening and closing the inlet and outlet channels. Thus no sealing fluid within the compression chamber is needed. 
Explosion proof versions with reduced leakage are available as well as ATEX compliant vacuum pumps and compressors.

Industrial screw vacuum pumps

The S-VSI screw vacuum pump (sizes 100 and 300) represents modern, state-of-the-art dry running vacuum technology that is not only extremely energy efficient and reliable but offers a low life cycle costs. It is used in a variety of industrial applications such as drying and packaging.
