SIHIextruvac
We are pleased to announce the release of two special close-coupled vacuum pump models designed specifically to handle the profile extrusion market. The new SIHIextruvac 30 USgpm!
In the plastic extrusion process, moldable plastics, often in the form of pellets are heated and forced through dies of the desired shape. Subsequently, the extruded profile passes to a calibration table where vacuum is used to ensure the final profile matches the desired shape and dimensions. Water is used continuously during the calibration process to permit controlled cooling of the profile. The vacuum pump must there-fore be capable of handling air/water mixtures, and in some cases large water flows.
The SIHIextruvac is applied to the handling and exhausting of dry and humid gases. These pumps are applied in all fields where a pressure of 100 to 900 mbar must be created by robust vacuum pumps. The SIHIextruvac
During operation the pump must continuously be supplied with service liquid, normally water, in order to eliminate the heat resulting from the gas compression and to replenish the liquid ring, because part of the liquid is leaving the pump together with the gas. It is possible to reuse the service liquid. The pumps are equipped with a device by which the contaminated service liquid can continuously be drained during operation (dirt drain), if necessary.
