Devi Hitech Engineers Private Limited

Cherlapalli, Hyderabad, Telangana

Devi liquid ring compressors are rotary machines in which the liquid is made to act as piston. This liquid will vary depending on the gas to be compressed the overhung shaft is supported by Angular contact bearings. Shaft sealing is provided by mechanical seal. We are having various models to suit the customer requirement. Our manufacturing range starts from 150 m3/ hr to 2500 m3/hr depending on operating conditions.

Some of the major Industries where these Compressors used are :
Chlor Alkali Industry :For compressing Chlorine Gas.
Petrochemical Industry :For compressing highly inflammable Gases like Flare Gas, Propane etc., .
Steel Industry :For compressing Argon Gas.

For compressing Air, Hydrogen peroxide and other critical Gases. These Compressors are used in highly corrosive and critical gas applications. At present we are manufacturing Single Stage Compressors which can develop a Pressure of up to 4.5 bar and on the verge of developing two stage Compressors for pressures up to 7.5 bar.

1. Metallurgy :We are supplying the Compressor Parts in Superior metallurgy suitable for particular Application
2. Shaft Sealing :Generally, we supply the Compressors with Mechanical Seal, but it may change basing on the requirement / specification of end user.
3. Design Features :Our Compressors are of Back pull out design with Spacer Coupling hence require less down time for maintenance
4. Performance Testing :We are having in-house Testing facilities for Testing the Compressors prior to dispatch as per API 681 Standards
5. Quality Systems :a) ISO 9001 - 2008 Certification

Devi Liquid Ring Vacuum Pumps are versatile , Horizontal Rotary Machines in which the Liquid is made to act as Piston.

Range :Capacities ranging from : 40 to 600 m3 / hr.

For handling Aggresive Gases or Vapours ( Chlorine , Argon etc.) In industries like Chloro Alkali and Allied Industries, Pulp and Paper Mills, Chemical Industries.

Horizontal , Single stage, Axial Flow, Pedestal type, with one rotating part i.e, Impeller / Rotor. The Rotor is supported by a pair of Angular Contact Ball Bearings and Roller Bearings.The Axial clearance can be adjusted very easily in these pumps.

The Liquid will vary depending on the gas to be Evacuated / Compressed.

Packed Gland or Single / Double Mechanical seal Depending on the process requirement and customer choice.

Alternatively we can supply these Vacuum Pumps with wetted parts in Hastle Alloy C , Alloy 20 , Stainless Steel , Carbon Steel depending on system requirements.
