|Principle of operation|
The machine casing is cylindrical having control disc on both sides. A consistently deviating impeller sporting curved blade revolves inside the casing. Water introduced in the system is set in rotary motion by the blades, forming water concentric ring inside the casing. During the process, cells are produced between the impeller blades and the ring. The cells thereby vary in volume from maximum to minimum after every revolution. The conveying medium gets inside the working chamber via the duct provided in the lateral control discs and is compressed by the downward trend in cells volume. Later it flows along with the cooling water via discharge exit provided in the control discs up to the delivery port.
Maximum achievable vacuum (Blank off) -40mm Hg abs.
