Vacuum Pumps And Systems

Our clients can avail from us, direct driven high vacuum pumps, which are manufactured using quality parts & components through advanced technology. The high capacity motor that we use in these pumps is coupled via flexible coupling. Smooth and quiet running operation is ensured by the special construction of this coupling and the use of quality tested material. Some of the major applications lie in metalizing, Distillation, Filtrations, Impregnation, Forming, Refining, Filling, Purifications, Vacuum Heat Treatment, Melting, Crystallizing, Electron Beam Welding, R & D Centers, Nuclear & Space applications.

Technical Specifications:

• In the pump cylinders, the rotor is mounted eccentrically
• The three radially sliding vanes divide the pump chambers into three sections
• Vanes are forced to slide against the cylinder walls due to rapid rotation of the rotor by means of centrifugal force
• The volume of the crescent shaped working space in cross section increases and decreases alternately, thus promoting pumping
• Viton '0' rings are used to seal the component parts
• To ensure easy disassembling and reassembling, all parts are pinned

Key Attributes:

• Superior pumping characteristics
• Low ultimate pressure
• Automatic airing & Isolation via centrifugal switch
• Sophisticated gas ballast valve
• High water vapor tolerance & low noise
• Compact, light & extremely durable
• K. F. small flange connections
• Reverse rotation prevention

The Shaft and attached rotor are mounted eccentrically in the pump cylinder. Rectangular Vanes fit into slots into the rotor. As the shaft and the rotor rotate, centrifugal force pushes the vanes out against the pump cylinder's inner surface. Gas is drawn through the pump cylinder, compressed and delivered through the exhaust tube.

Features :

• Models are available in both belt-driven and directly cupled mechanism.
• All models are air cooled type

Accessories :

• Vacuum guage with regulator and adaptor
• Pressure guage with regulator and adaptor
• Inlet Filter
• Exhaust Filter

At most competitive prices, we provide our clients with a high quality range of rotary vane direct driven vacuum pumps. These pumps are made at par with the international standards. Coupled directly to the electric motor, these pumps run at much higher rpm than that of conventional belt driven vacuum pump. World class performance and durability are some of the highlighted features of these pumps. which ensure matching performance with any world leader.

Pumping Mechanism :

• The rotor is mounted eccentrically in the pump cylinder
• The three radially sliding vanes divide the pump chambers into three sections
• Rapid rotation of the rotor forces the vanes to slide against the cylinder walls via centrifugal force
• The pumping is brought about by alternately increasing and decreasing the volume of the working space which is of crescent shape in the cross section
• Rubber 'O' rings sealed component parts
• Pined parts for ensuring easy disassembling and reassembling

Salient Features :

• It requires less quantity of oil
• Compact in size
• Least oil contamination
• Low power consumption
• Overall battery efficiency
• Higher vacuum
• Low operating cost
• Easy servicing
• No maintenance
• Less prone to corrosion
• More suitable to moisture handling

Application :

• Metalizing
• Distillation
• Filtration
• Impregnation
• Forming
• Refining
• Filling
• Purification
• Vacuum Heat Treatment
• Melting
• Crystallizing
• Electron Beam Welding
• Nuclear & Space Application

• No moving parts.
• Simple robust construction.
• Quick and simple replacement of any worn out part.
• Available in single and multiple stages.

1. The Driving Nozzle
2. The Diffusor
3. The Suction Chamber

The flow chanel of the diffusor consist of a part converging in the direction of the flow (the inlet cone), a cylindrical piece (the throat) and a diverging part (the outlet cone). The operation of jet ejectors is based on the fact that the motive medium jet (water of steam), leaving the driving nozzle entrains air from the suction chamber & compress it to atmospheric pressure.

Applications :

• Distillation
• Vacuum Impregnation
• Crystallisation
• Filteration etc.

We provide the clients with liquid ring vacuum pumps, which are manufactured as per the industry standards. Clients can avail these vacuum pumps in different specifications and models as per their specific requirements. Our precision engineered vacuum pumps are designed to deliver enhanced performance.

Technical Specifications:

• In the pumping chamber, an impeller is arranged, which is partly filled with water. This impeller formed by the casing and the control discs
• Between the casing and the control discs located on both the sides, as the impeller turns, forming a rotating water ring in the varying space, the water is flung outwards
• The space between the impeller vanes and the volume of the pockets is sealed off by the water, which increases and decreases as the impeller rotates
• The water- ring sectors pulsating in the chambers between the vanes act as liquid pistons
• Increasing volume of the gas is drawn through the intake parts into chambers as the water recedes
• The gas is further compressed as the impeller continues to rotate and the liquid pistons are forced deeper into the chambers
• The water is segregated from the gas again in a separator connected on the discharge side of the pump

Features:

• Direct Coupled
• Used as a compressor by connecting a liquid separator in a discharge line
• Delivery of clean and oil free air
• Handles high volume of liquid vapor

Applications:

• Distillation
• Filtration
• Drying
• Hydro Extraction
• Evaporation
• Crystallization
• Molding
