Vacum Pump WY0700 by Busch Vacuum India Pvt Ltd.

Higher pumping speedand improved ultimate pressure: Puma WY vacuum boosters increase the performance of your vacuum system, making it more efficient and economical. Available in six different sizes, Puma WY vacuum boosters can be designed to perfectly suit all fine and high-vacuum applications in which the performance of the fore pump must be drastically increased or optimally adapted to the process.The Puma WY 0700 B to WY 1250 B are the two medium-sized vacuum boosters in this series.

Ideal for difficult processes
Puma WY vacuum boosters are perfect booster pumps for COBRA screw vacuum pumps and other backing pumps. They are excellently suited to pump aggressive or toxic gases through a water-cooled canned motor, which is fitted as standard. Due to the absence of shift passages, it enables absolute leaktightness to the atmosphere.

The Puma WY can be controlled using a pressure switch that activates the vacuum boosters of the backing pump once has achieved the optimum pressure. Alternatively, the Puma WY is also available in versions that are controlled by frequency converters.
Technical specifications
Within the housing of Puma WY vacuum boosters, two pistons rotate synchronously. Thanks to the special profile of the rotating pistons and their precise manufacturing, they do not come into contact with each other or the housing. This makes it possible to pump a medium without the need for any operating fluids. The synchronous rotation of the two rolling pistons is driven by a pair of gear wheels located on the shaft ends in the gearbox and separated from the compression chamber. In combination with a COBRA screw vacuum pump that is also driven by a canned motor, Puma WY vacuum boosters are used in many applications in the semiconductor industry, the manufacture of photovoltaic modules and flat-screen displays, silicon production and surface treatment.
