The Liquid ring vacuum pump is the best solution for vacuum applications where wet, or extremely humid, and slightly contaminated gases are ingested. For several of these applications, water is the best media that can be used for the water ring.

Liquid ring vacuum pump Single Two stage

TWO-STAGE LIQUID RING VACUUM PUMP

We are manufacturing 6 different Models ranging from JDWVS- 4D to JDWVS- 40D. The smallest Vacuum Pump is having a full open suction capacity of 50 M3/Hr and is being driven with 3 HP Electric Motor. While the biggest model of the Vacuum pump is having a full open suction capacity of 400 m3/hr and is being driven with 20 HP Electric Motor.
Two-stage vacuum pumps typically produce vacuum to 720 mm of hg, assuming air is being pumped and the seal-liquid water at 30°C (85F) or less. Dry air and 30°C Degree Celsius water temperature is the standard performance basis which most manufacturers use for their performance curves.

DETAILS REQUIRED FOR QUOTATION
  • Application
  • Capacity (M3/Hr or CFM)
  • Vacuum (inch WG or mm WG)
  • Seal Water Temperature (°F or °C)
  • Air Gas Temperature (°F or °C)

WORKING PRINCIPLE
A dynamically balanced cylindrical rotor with a hollow hub and a series of curved blades is rotated freely in the eccentric casing. The sufficient sealing water / liquid forms a solid ring on the periphery of the casing, due to the centrifugal force, the rotor is rotated in the eccentric casing, the rotating blade creates working spaces whose volume increases as the rotor rotates from lower to upper vertex and decreases as the rotor rotates from upper vertex to lower vertex. The uniform distribution of working spaces on the rotor periphery results in continuous suction and exhaust of gases.

MATERIAL OF CONSTRUCTION
The Pump can be supplied in several materials to suit various applications;
  • Cast Iron
  • Partially or Complete Bronze, SS 304, SS316, Alloy 20, Hastalloy - C,
  • Rubber Lined 
  • Other as per customer requirement

FEATURES
  • Simple & Trouble-free operation
  • Suitable for low and high vacuum applications
  • Rugged construction for heavy-duty application
  • No metallic contact inside machine hence less wear & tear,
  • Moist air, vapors, aggressive gases & dust-laden gases can be handled
  • No contamination of medium passing through
  • The leakproof sealing arrangement can be done
  • Clean & Oil-free exhaust / discharge
  • Compression takes place with a small temperature rise.
  • Compact unit due to direct drive
  • Low Power and Water consumption.

APPLICATIONS
  • Power Industry: Pneumatic conveying of fly ash, vacuum priming, vacuum deaeration, and condenser initial evacuation.
  • Sugar & Distillery Industries: Vacuum filtration.
  • Plastic Industries: Degassing, drying & conveying
  • Environmental Industry: Vacuum priming, digester gas compression, wastewater disposal.
  • Petroleum Refining Industry: Crude oil stabilization, crude oil vacuum distillation, filtering / de-waxing.
