Water Ring Vacuum Pump
The casing of the machine is cylindrical with control disc on either side. An eccentrically located impeller with curved blades rotates within the casing. The liquid (preferably ) introduced is set into rotary motion by the blades, thus forming the water ring concentric with the casing. Cells are formed between the ring and the blades of the impeller which vary in volume from maximum to minimum with each revolution. The conveying medium enters the working chamber through the opening in the lateral control discs and is compressed by the decrease in volume of the cells. It then flows together with the cooling through discharge opening in the control discs to the delivery port.
These machines are principally used as Vacuum Pumps. However for specific application they are also used as Compressors. The advantage of these machines is their simple construction and trouble free operation. With proper MOC it can easily handle moist air and aggressive and dust laden gases.
- Simple construction & easy maintenance. Compact unit due to direct drive
- Oll free Exhaust
USHA Pumps are used primarly for the following major applications: Vacuum Filteration Vacuum Distillation Moisture Extraction Solvent Recovery Priming Vacuum Brake testing in Railways. Pneumatic-Conveying Evaporation Deaeration Vacuum Condensation • Drying Systems Extruder Venting
