4 ELMO- Side-Channel Blowers A versatile solution for flexible use Whether vacuum pump or compressor, whether handling air, non-explosive gases or gas-air mixtures ELMO- side-channel blowers are oil-free, maintenance-free and ever reliable in f a s operation. The reason: the impellers are mounted directly on the motor shaft and compress entirely without friction. Maximum operational reliability, including at high differential pressures, is ensured by the arrangement of the bearings outside the compression chamber. All of this makes ELMO- uniquely robust and maintenance-free even in continuous duty. g d h lexible and powerful Short delivery time, easy installation The ELMO- range 2BH1 and 2BH7 vacuum pumps and compressors are available in a huge product range with over 80 sizes. They therefore cover the most varied requirements flexibly and powerfully, even in applications which are otherwise the preserve of more sensitive dry-running rotary-vane compressors or noisy rotary-piston blowers. ELMO- vacuum pumps and compressors are also available with integrated busable frequency converters for speed variation between 2200 and 00 rpm. This allows any operating point to be precisely selected and controlled without complex commissioning or additional wiring. ELMO- vacuum pumps and compressors are available immediately in all common voltages. Especially for resellers there are /-Hz-wide-range voltages: consequently, 95% of all world voltages are covered. ELMO- vacuum pumps and compressors come ready for connection. or the customer this means: just mount in any position, connect the suction/discharge lines to the system, wire up the electrical connections and the ELMO- is ready for operation. Motor (degree of protection IP 55) as well as suction- and discharge-side silencers are integrated in the compact design. ELMO- 2BH7, single-stage for high pressure ranges. ELMO- side-channel blower 2BH1 single-stage version. 2 ELMO- side-channel blower 2BH1 two-stage, for tougher requirements. ELMO-S 2BH1 with integrated frequency converter for high volume flows and/or automatic modification to changing loads.

5 2BH operating principle a Casing s Side channel d Inlet slot f Impeller g Discharge slot h oot plate ELMO- vacuum pumps and compressors work according to the side-channel principle. The gas flows through the compressor along a helical trajectory and is repeatedly accelerated and thereby repeatedly compressed according to the required operating point. Consequently, much higher pressures are obtained than it is possible with radial blowers of identical impeller diameter and speed. Applications Pneumatic conveying systems Lifting and holding of parts by vacuum Packaging machines Aeration of sewage-treatment plants illing of bags/bottles/hoppers Soil remediation Thermoforming Sorting/enveloping of letters ood-processing Laser printers Dental suction equipment Paper processing Printers/copiers Textile machines Aeration of fish ponds as analysis Swimming-pool equipment/whirlpools ELMO- 2BH7, two-stage the reliable system for high differential pressures 2BH100 Little Star drive via an electronically commutated, permanentfield d.c. motor.

36 ELMO-L Vacuum Pumps L The complete system with patented discharge-air cooling ELMO-L vacuum pumps are compact, ready-to-connect systems: connect the power supply, fill the water tank and install the suction line finished. No need for a foundation. ELMO-L pumps are 100% oil-free. Throughout the entire working range the casing temperature is max. 15 C above room temperature. The discharge air leaves the pump at room temperature or lower clean and dust-free. Reliable in continuous duty Insensitive to condensate from the air being handled and unaffected by water vapour. Problem-free continuous duty at end vacuum (closed suction gate valve) is guaranteed: the pump remains cold, power consumption is reduced to a minimum. At Hz the sound-pressure level is between 6 and 72 db (A), depending on size. Sound-absorbing covers and discharge-air silencers are therefore not needed. The complete vacuum system is a lowmaintenance system. Thanks to contact-free compression, it is wear-free in operation i.e. no periodic maintenance, lubrication or replacement of wearing parts. No need for additional energy: patented ELMO discharge-air cooling Discharge-air cooling in ELMO-L vacuum pumps is by means of a special, patented process with no need for additional outside energy. Unlike conventional closed-circuit systems with liquid-ring vacuum pumps (1), the ELMO-L system uses a special dischargeair cooler () to cool the water-vapoursaturated, hot discharge-air downstream of the water separator (2). The temperature falls below room temperature. Water vapour condenses out of the discharge air as a result of cooling. This condensate is returned to the operating liquid. This means that ELMO-L vacuum pumps can be operated without the continuous supply of make-up water. A further advantage over conventional systems is, that there are no problems with materials as a result of corrosive pollutants, because there is no build-up of dissolved constituents in the operating liquid as a consequence of the escape of water vapour on the discharge side. ELMO-L vacuum pump, compact version ready to connect, easy fit, highly integrated. ELMO-L vacuum pump 2BL1 0 more power and flexibility, for decentralised mounting. 4

42 ELMO- Liquid-Ring Vacuum Pumps/Compressors Robust technology for every application We have been building liquid-ring vacuum pumps and compressors for almost 100 years and have acquired a unique level of know-how which we systematically build upon with great a s dfg h success throughout the world. Whether from our 2BV, 2BE or 2B/2BK range, ELMO- liquid-ring vacuum pumps and compressors are ideally equipped for use in wet processes. They are insensitive to thermal loading, condensate, dust, dirt particles and water slugs. They extract or compress even explosive gas mixtures safely and reliably. ELMO- vacuum pumps and compressors are 100% oil-free in operation. The suction capacity is maximised by internal condensation of the steam in the suction flow, which means maximum performance when extracting steam-air mixtures. Operating principle of a 2BE pump a Operating liquid s Casing d Discharge port f Impeller hub g Impeller h Suction port M o n o b l o c k p u m p s: ELMO- vacuum pumps 2BV2/2BV5 (IP 54 degree of protection) motor and pump form one structural unit amazingly space-saving. ELMO- vacuum pumps 2BV (IP 54) reliable monoblock pumps for low suction flows. ELMO- vacuum pumps 2BV7 (IP 55) ultra-compact with the lowest water consumption. ELMO- vacuum pumps 2BV6 (IP 55, explosion protected) with single or double mechanical seals and in stainless steel. 40

43 Simple and robust The principle is simple and robust: the impeller is the only moving part and rotates without making contact that means without contact with the casing or with the port plates, which limit the end faces of the impeller. Sealing is provided by an operating liquid ring (1) which rotates together with the impeller (5) in the casing (2). At the topmost point, the liquid completely fills the impeller chamber; and, as the impeller rotates around, the liquid falls away from the hub (4). As the space between the operating liquid and the impeller hub increases, it is filled with gas, which is drawn in through the suction port (6) of the port plate. At the discharge-side, the liquid ring moves back towards the hub and compresses the gas just like a piston, which is then discharged through the flexible discharge port () of the port plate. Applications Mining Chemical, pharmaceutical and refinery plants Evacuation of condensers in steam-electric power plants Plastic industry Medical technology ood industry Paper industry Textile industry Environmental engineering Vacuum filtration for processing of ore Process engineering Sugar factories M o d u l a r d e s i g n : ELMO- vacuum unit 2BE1 successfully used worldwide in moist processes.
