CONSTRUCTION The SIHIcompart vacuum units consist of various components which are assembled together to form a compact unit with an optional function range. The LEM liquid ring vacuum pump utilised in these units 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 • Cavitation protection as standard The SIHIcomparf vacuum units are produced as a service liquid saving arrangement and can be supplied with or without a heat exchanger. APPLICATION For handling dry and saturated forms of gases. Small quantities of entrained liquid in the suction gas stream can also be dealt with. The SIHIcompart is designed for vacuum applications of between 33 and 900 mbar. This range can be extended when used in conjunction with the respective gas operated ejector (up to 8 mbar). 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. Depending on the chosen arrangement and application the service liquid can be either totally or partially re-used within the system (combined- or circulating operation). In the case of circulating operation with heat exchanger the pressure difference between the suction inlet and discharge outlet should be 200 mbar at minimum. The direction of rotation is clockwise when viewed from the drive end of the pump. The combination of several limiting values is not admissible.
