November 2007. We improved one of our well-known vacuum pumps

Applications

These units have been designed and manufactured to be installed on glass or marble working machines, where non aggressive liquids (typically cooling liquids) could be sucked by the vacuum pumps.

Description

These unit, have a stand-alone configuration and a very compact shape; they are connected to the working machines, usually with flexible pipes. A ball valve installed at the tank intake allows the insulation of the unit from the working machine during routine maintenance operations. The first separation (air-liquid) is done in the 25 litres, aluminium tank in which the internal configuration generates the cyclone effect. On the external surface of the tank is lodged a floating type level gauge that allows an easy control of the amount of liquid inside and it is equipped with a sensor that provide an electric signal when the maximum level is reached. Moreover the tank is equipped with an automatic drain valve that acts when the pump is stopped. Then the fluid reaches the external condensate separator filter on which it is installed a vacuum gauge and a valve. The filter is connected to the pump by a rigid pipe on which is lodged an auxiliary check valve. The LB series, WR version are the vacuum pump installed on these units that are fitted with the high efficiency gas ballast device that allow the pump to separate the moisture still present and to evacuate it when the pump is stopped
