There are cases in which it is necessary to ensure vacuum seven days a week round the clock. For example, in hospitals or in research laboratories, where the vacuum centralization must be continuous and efficient.
Vuototecnica designed for these situations DSV vertical security vacuum pump set conceived for the normal operation of a pump with the option to insert a second one when higher consumptions are expected, or in the case in which the predetermined vacuum minimum value falls accidentally. When this happens, a visible and audible alarm system starts, on the electrical panel, and even from a distance.
In the electrical control panel there are: an automatic time reverser in order to be sure that the pumps work alternately, wearing out the same way; switches for selecting the pumps operation (manual or automatic); a counter for counting the hours of operation of each pump. For additional security, electrical board is enclosed in a special metal case.
Each vacuum pump set is also made up of:
– A vertical tank made of leak-proof, welded sheet steel, with a vacuum meter to read the degree of vacuum at all times;
– Two rotary vane pumps with manual valves to exclude them when necessary;
– Three vacuum switches to establish the minimum level of security below which the alarm is activated and to adjust the vacuum range within which each pump has to work;
– A valve for intercepting the vacuum;
– A tap for condensate discharge.
