MULTI JECTOR® Vacuum Pumps and Vacuum Components by VOLKMANN multiple stage ejectors energy-saving compact ejectors stainless steel Vacuum Pumps vacuum switches vacuum filters

VOLKMANN has been successfully supplying Vacuum Pumps, designed to suit a wide range of vacuum applications, for more than 25 years. The basis of this success has been the continuous development and innovative approach taken to satisfy the ever increasing variety of applications and special technical requirements demanded. This has resulted in many solutions which help to save the user time and costs. The Volkmann MULTIJECTOR ® series of vacuum pumps contains various pump types which have been designed specifically to suit the wide range of different duties which present themselves and the new...

... the multiple stage MULTIJECTOR® Volkmann Multijectors use multiple ejector stages, which save compressed air and reduce running costs. When additional nozzles are built behind the diffuser, the air ejecting from the first stage, (which consists of compressed air mixed with the suction air induced by the venturi effect), serves the following stage as a „free“ propulsion jet, which does likewise for subsequent stages. These additional stages do not reach the high vacuum of the first stage, but they vastly enlarge the effective suction capacity, at reduced vacuum, for no additional compressed...

Volkmann can supply valuable application know-how and help with plant designs and lay-outs – talk to us. Some typical applications for Multijector pumps include: Vacuum lifting and holding ... of all sorts of items ranging from eggs, china, work pieces, steel sheets, to stone blocks, or other heavy items. No matter if a suction cup grips eggs or opens a bag, a vacuum transporting belt conveys steel sheet billets, a suction plate lifts up heavy granite plates or a robot arm with vacuum grippers fits in system subassemblies or car windscreens - Multijectors simplify and protect many handling tasks...

Further energy saving devices in vacuum applications: Restricting the vacuum In handling applications, if the area of the suction cup is maximised, then only a relatively low vacuum has to be created to achieve the required holding force. For example, using a Multijector M or G type, approximately 93 % of the energy requirement can be saved, in most applications, when the vacuum is reduced from -900 to -500 mbar. Hence, only 7 % of the original energy requirement is needed, which gives considerable cost savings. Restricting the operating pressure Use of a simple pressure controller to adjust...

in comparison to usual one-stage compact-ejectors The MULTIJECTOR® K series is our youngest ejector family and worldwide the first multiple stage compact-ejector. With this compactejector you really save compressed air at automation applications and lower your overhead expenses. It is unbelievable how lavish many single stage compact-ejectors are with compressed air. We are glad about that, because this way a newly bought MULTIJECTOR® K can often pay for itself in less than one year. The MULTIJECTOR® K is space and energy-saving and was developed by us especially for handling and automation applications....

Multijector pumps of the M- and ML-series work with three ejector stages which are connected in a row. Their robust and compact aluminium casing makes the pump resistant even to strong mechanical or thermal loads. Nevertheless they are very light and offer considerable amounts of suction air at a small size. The compact form allows them to be mounted directly at the location where vacuum is needed. Their high efficiency makes the VOLKMANN Multijectors of the M- and ML-series the ideal vacuum pump for a multitude of different handling applications, for vacuum packing, vacuum testing, vacuum transportation,...

Our Multijector Vacuum Pumps of the G- and GL-series are four-stage ejectors and offer an even better efficiency especially at free aspiration and low vacuum. They consist of a light and nevertheless tough modular Aluminium design. As usual for Multijectors, also this pump family can be installed easily: Just connect compressed air- and vacuum line, that‘s all. The G- and GL-series are our top-models for fast evacuation of big volumes and for achieving high suction performance, e. g. for evacuation of casting-, press- and deep-drawing moulds, for vacuum conveying, for suction of abrasives and...
