DRY VACUUM PUMP

Engineered Excellence in Dry Vacuum Pumps for Industrial Solutions

Dry (hydrocarbon free in the process) Vacuum Pumps plays an important part in many vacuum applications and environments.

Dry vacuum pumps are remarkably simple, yet sophisticated, reliable, and highly efficient. The dry and contact-free operation requires no lubrication in the pumping chamber. This translates into major advantages: no process contamination and no pollution caused by the pump operation.

Dry vacuum pumps can safely and reliably handle corrosives, organics, inorganics, and solvents because of its oil-free, non-contacting single or multi-stage claw design.

MULTI STAGE DRY VACUUM PUMP

Features

Three & Four Stage Compression (Dp250 & Dp400) :

Faster Air Removal And Higher Rate Of Compression

Compact Design

Pump Mounted On A Stand – Alone Frame Occupying A Footprint <1 Sq.M

Vertical Mount

Self- Draining Technology And A Vertical Mount Design Make The Pump More Versatile And Rugged .

Cartridge – Type Inlet Side Bearing

Grease Lubricated Roller Bearing Ideal For Supporting Radial Loads. Easy Replacement Of Inlet Side Roller Bearing And Seals Without Removing Stages.

Angular Contact Bearing

Double Row Angular Contact Bearing Near The Motor Take Care Of Simultaneously Acting Radial And Axial Loads.

Relief Valve

A Third Stage Relief Valve Avoids High Pressure Build Up Within Stage Compression Cycle, If The Pump Crosses 300mbar

Temperature Control System

Helps Is Preventing Condensation/Deposition Of Chemicals In The Stages. It Maintains The Set Cooling Water Through The Heat Exchanger. The Set Temperature Is Defined By The Application.

Intelligent In-Direct Cooling (Thermosiphon)

Unidirectional Flow Of Water Through The Heat Exchanger Will Eliminate Blockages That May Occur In Industrial Water Supplies. Cleaning The Heat Exchanger Is Also Easier If Clogging Occurs, When Compared To The Clogging Faced Within The Pump Jacket.

Inlet Purge

Protection From Process Substances Entering Into The Pump Chamber And Pipe Lines Through Purging A High Pressure Nitrogen At The Inlet.

Shaft Seal Purge

It Is Essential To Maintain Shaft Seals At A Positive Pressure During Operation Helping To Prevent Entry Of Corrosive/Toxic Gases Towards The Pump Gear Cover. Life Of Shaft Seals Increases As We Eliminate The Risk Of Damage That May Cause From Debris Or Any Other Corrosive/Toxic Gases. A Controlled And Customizable Feature Helps The User To Determine The Purge Frequency Based On The Usage And Application.

Solvent Purge

Internal Surfaces Of The Pump Are More Prone To Corrosion And By-Product Settlement. This Is Prevented By Running The Solvent Used For Distillation. The Solvent Purge Will Rinse The Pump Internals And Keep It Safe From Possible Corrosion And Process Substances.
