Vacuum-Compact Systems SIHImodular PL 26 M, PL 51 M ANLAGENTECHNIK PL 1 133.94400.51.01 E 06/2000 SAT Pressure range: 33 bis 1013 mbar Suction capacity : 3 bis 58 m³/h DESIGN AND CONSTRUCTION The SIHImodular systems consist of a various components which are assembled together to form a compact unit. Each unit can be varied in accordance with the respective application. The LEM liquid ring vacuum pump utilised in these systems is of a single stage design and of a simple and robust construction with the following features: · Non polluting due to near isothermal compression · Oil free, no lubrication in the working chamber · Capable of handling nearly all gases and vapours · Small quantities of entrained liquid can be handled · Easy to maintain and reliable operation · Low noise and virtually free from vibration · Anti cavitation protection as standard The SIHImodular systems are offered as a service liquid saving arrangement and can be supplied with or without a heat exchanger. APPLICATION As with the other SIHI liquid ring vacuum pumps this type is also capable of handling dry and saturated forms of gases. Small quantities of entrained liquid in the suction gas stream can also be dealt with. The SIHImodular is designed for vacuum applications of between 33-900 mbar, however, this range can be extended when used in conjunction with the respective gas operated ejector. (See standard catalogue for details). PL 91 M.A.M 55 0.0A NOTE During its operation, the liquid ring vacuum pump must be continuously supplied with service liquid, normally water, in order to eliminate the heat resulting from the gas compression, and to prevent the pump from dry running operation. The service liquid is separated from the process gas in a separator. Dependent on the chosen arrangement and proposed application, the necessary service liquid can be either totally or partially recirculated within the system, conserving the amount of fresh make up liquid required. However, when using the total recirculated arrangement, the operating suction pressure must be 800 mbar or lower. The direction of rotation is clockwise when viewed from the drive end of the pump.
