Description: Energy Saver Vacuum Pool System is formed by combination of two vacuum pumps and a reservoir tank that fulfills fluctuating demand keeping the vacuum virtually constant. The system is also designed for unique capacity control to save on electrical energy. The other important feature of the system is re-circulation of sealing liquid, which saves on the cost of sealing liquid and reduces the load on effluent treatment. Two or more vacuum pumps operate in a parallel operation through a common reservoir. During operation one pump runs continuously and the second pump is switched on & off depending upon the process demand and keeping vacuum virtually constant to the set value.
