Water Ring Vaccum Pumps

Product Description

Water Ring Vaccum Pumps

26 years of efficient work has led us to the extreme level recognition in the field of manufacturing, exporting and supplying Water Ring Vacuum Pumps. Capable of bearing withstanding heavy load of water vapors, this vacuum pump is extensively used in distillation, filtration, vacuum drying and water extraction from paper & cloth. Water Ring Vacuum Pumps are accredited at global level due to its sturdy construction, noiseless running and oil free compressed air. The pump is available at affordable prices.

Further Details:

"JEBIVAK" Water-ring pumps are basically liquid-ring pumps. Since water being very commonly used as the sealing liquid,these are called as Water-ring pumps. These pumps are specially designed for handling gases, damp media or moist air and even corrosive vapours by proper selection of material of construction. The pumps can be driven by direct drive or V-belt drive arrangement with Electric Motors or Diesel Engines.

"JEBIVAK" pumps are built up with high accuracy and close tolerances to give best performance. The construction is robust but simple and consisting of very few components. Dismantling and assembling of the pump is therefore very easy. The major components are casing, impeller and control discs. The material of these components are chosen depending on the application. Standard supply is with casing in Cast Iron and impeller and control discs in dynamically balanced to maximum accuracy and it rotates on roller bearing at both the ends. The running is therefore smooth and the vibration free. It is assembled eccentrically in the casing having control discs on sides. Standard pumps are supplied with gland-pack arrangement however mechanical seals aslo can be provided whenever necessary.

Generally the pumps are silent except very little humming noise at the exhaust. This humming noise also can be reduced by using a silencer in the discharge line. A general lay-out is shown on the next page. It is advisable to use a non return valve in the suction line which prevents back-flow of liquid in case of stoppage of pump under vacuum. Pump creates rattling noise in the final range of vacuum due to cavitation. A vent-cock is provided on the side casing-cover to leak in air and reduce cavitation noise. Ultimate vacuum attainable by the pumps depend on the ring-liquid, temperature and barometric pressure. It is 710mm of Hg. with ring-liquid as water at 30oC having 0.8 to 1.0 Kg/cm2 pressure and barometer at 760mm of Hg.

This pump can also be used as a Compressor by using a liquid separator in the discharge line. The compressed air available is little moist but clean and oil-free. Maximum attainable pressure is 1.8 Kg/cm2. A general lay-out of compressor is as shown on the next page.

Advantages and Applications
