water ring or liquid ring vacuum pump are designed for lower vacuum air suction. a typical range of its vacuum is 680 to 720 mm of Hg.
The good feature of this pump is , as there is water rotating in the pump , it can withstand heavy vapour or steam as its input , or highly moisture content air.
Also , sealing is created by water and not by sprint supported blades, it can also accommodate certain amount of dust with it too.
This type of pump primarily used in filteration or where lower amount of vacuum is required. another application of such pump is in distillation , where the matrial to be distilled contain large amount of water. in such cases, water ring vacuum pump can be used along with oil seal vacuum pump in parallel and run alternatively to create desired vacuum condition.

accessories available with parag make oil seal high vacuum pump
Accessories:
Air Ballast:
This is a vent pipe introducing air before actual compression which eliminates condensation of the sucked vapour, there by avoiding contamination of oil.
Air Admittance Valve:
It is electromagnetic solenoid type which admits air into the system as soon as the power supply fails. This prevents back-flow of oil to the system.
Non-Return Valve:
It is rubber diaphragm type, spring loaded valve, which prevents back-flow of oil to the system as soon as pump stops. These can not be used to hodl the vacuum in the system for longer period.
Moisture Trap, Inlet Dust Filter, Vacuum Gauge with Regulator, Trolly for small Pumps.
USE Oil: ENCLO - 46 (HP) SAE - 30 or Equivalent Vacuum Oil.
Model HL - 300 - II and above, are provided with water cooling jacket.
Vacuum Measured Mcleod gauge at suction port of the pump.
operating principle , liquid ring vacuum pump
Operating Principle:
The working parts of the Parag Pumps cossets of amulti-vane impeller mounted eccentrically in a round casing which is partly filled with liquid (usually water). As the impeller rotate the liquid is thrown by centrifugal force to from a liquid ring which is connector with the periphery of the casing. Due to the eccentric position of the impeller relative to the casing and liquid ring the spaces between the impeller vanes fill with liquid during rotation and any air or gas trapped in the impeller space or cell is compressed and discharged from the casing through the outlet part leaving the cell available to receive air or gas as it is presented to the inlet port of the casing. In addition to being the compressing medium the liquid ring performs three other important functions. It absorbs the heat generated by compression nd friction.
