SIDE CHANNEL BLOWERS

Leading in Excellence and Innovativeness: Side Channel Blowers from Elmo Rietschle

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. Our side channel blowers are available in a wide selection for performance ranges up to 3,000 m³/h and differential pressures of up to 1,000 mbar. They cover the most varied requirements flexibly and powerfully. The G-Series side channel blowers feature 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.

This makes them the ideal solution for worldwide use without modifications or tests in Europe, Asia and the Americas. They are mostly available ex stock and for some types with ATEX certification. Elmo Rietschle offers a large range of accessories that are ideally suited for these machines. A special sound protection hood was designed for noise sensitive environments such as schools, living quarters, hospitals and production facilities. They can be installed outside, are maintenance free and easy to transport. An additional rigid silencer is now available that will reduce the noise level even further.

Oil Lubricated Rotary Vane Vacuum Pumps

V-VCE, V-VGD, V-VCB, and V-VC ranges:

Oil-lubricated rotary vane vacuum pumps designed and built by Elmo Rietschle are used in a wide variety of industrial applications. We offer the largest range of oil-flooded vacuum pumps for industrial coarse and fine vacuum operation.

The V-VC range is based on three different designs:

Compact pumps with overhung bearing design
Medium ranges with rotors supported on both sides and flexible coupling
Large pumps with rotors supported on both sides, flexible coupling and double wall cylinder

V-VC rotary vane vacuum pumps are air cooled in standard version. An oil-water cooler is available for high ambient temperatures or for heat recovery. The exhaust air is cleaned in a built-in mist filter with a very high separation efficiency ensuring oil free operation in all working conditions. During service, the oil mist filter can be changed quickly via the maintenance cover, which is sealed by an O-ring, or for sizes 50 – 150 directly from the outside with a bayonet fixing. All pumps from range 25 up feature a gas ballast valve as standard. This optimises the water vapour and when the pump reaches its operating temperature any water vapour pumped passes through as a gas, without condensing.

Furthermore, an improved double chamber oil tank with two sight glasses, which maintains the oil supply even under difficult operation conditions, has been incorporated in V-VC vacuum pumps from range 25 on (sizes 50–150: optional). With the use of non-emulsifying oils – such as Elmo Rietschle MULTI-LUBE – any condensate and oil will separate after the pump is switched off.

The water in the oil tank can be seen in the lower inspection glass and then be drained before causing any harm to the vacuum pump.

Dry Running Rotary Vane Vacuum Pumps, Compressors and Pressure-Vacuum Pumps

V-VTE, V-DTE ranges: Compact V-VTE vacuum pumps and V-DTE compressors are each available in four sizes. Low noise and reliability make this series an ideal choice for many OEM applications.

V-VTN, V-DTN, V-KTN ranges: Our medium size dry pumps are available in vacuum (V-VTN), pressure (V-DTN) and combination models (V-KTN). Design features of these include maximized cooling air pathways, heat resistant materials, sound reduction covers and relief valves.

V-VTA, V-DTA, V-KTA ranges: The next largest group of dry rotary vane pumps also offers all operation types – vacuum (V-VTA), pressure (V-DTA) and combination models (V-KTA). Developed as continuous duty pumps for printing and paper handling machines, this series is now used widely in many industrial applications.

V-VTR, V-DTR, V-KTR ranges: A new range of rotary vane pumps is available as vacuum (V-VTR), compressor (V-DTR) and as combined pressure-vacuum version (V-KTR). The benefits of the new range are visible at a glance: maintenance and control panel are placed on one side for easy access to filters and valves. Additional features include heat reduction through large cooling air pathways and vents. Design features such as the solid ribs, optimised cooling air circulation, thermal separation of suction and compression chambers within the filter casing, as well as a minimum number of connected heat transferring parts reduce machine temperatures.

L-SERIES

- LIQUID RING PUMPS

Liquid Ring Vacuum Pumps and Compressors

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. Our 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.

Reliable and economical: The L-Series liquid ring vacuum pumps and compressors last longer and are more reliable than modular pumps and will considerably reduce your operating costs.

Safe and resilient: Our pumps have stainless steel shafts which makes them corrosion resistant. They work safely and reliably even under extreme conditions, like those in humid processes.

No more limescale: The unique ceramic internal coating of the L-Series pump casings means that the pumps will not calcify due to fluid deposits. The special coating has been developed by us in cooperation with our expert partners. The benefit: years of optimal performance at low maintenance cost.

For use worldwide: The L-Series monoblock pumps feature voltage range motors for 50 and 60 Hz in protection class IP55 (insulation class F) and are certified UL 1450 and CAN/CSA C22.2 No. 68-09. They can be used all over the world – in Europe, Asia or the Americas. ATEX certified machines are available in many sizes.

C-SERIES

- CLAW TECHNOLOGY

Claw Vacuum Pumps, Compressors and Pressure-Vacuum Pumps

Our dry running C-Series generates contact free vacuum or compressed air efficiently and economically due to the principle of internal compression. This leads to considerable energy savings compared to the traditional rotary lobe design without internal compression.

Wide spectrum of performance with the C-VLR claw vacuum pumps and C-DLR claw compressors the following ultimate pressures are attainable during continuous operation: vacuum up to 50 mbar (abs.) and pressure up to 2.2 bar. Combination pressure-vacuum pumps provide under pressure up to -0.6 bar and overpressure up to +1.0 bar.

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. The overhung rotor design in all sizes up to 300 is another outstanding feature of this technology. Gas tight versions with reduced leakage rates are available. We hold the patent on the newly designed triple lobe rotors with intermediate charging of air – for the first time vacuum and pressure are being created in one stage. Explosion proof versions with reduced leakage are available as well as ATEX compliant vacuum pumps and compressors.

R-SERIES

- ROTARY LOBE

Elmo Rietschle R-series Rotary Lobe

Elmo Rietschle compact rotary lobe blowers belong to the group of dry running positive displacement pumps.
