New from DVP Vacuum Technology is a range of pump vessel units, 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.
These units have a standalone 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 litre 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 provides 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 onto which 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 'antisuck' back valve.
The vacuum pumps installed on these units are fitted with a high efficiency gas ballast device that allows the pump to separate the moisture still present and to evacuate it when the pump is stopped.
