Vacuum

Our vacuum systems may include in one skid: vacuum pumps, boosters, separators and recirculation pumps. The exact configuration of the system depends upon the process and customer’s specifications. When using liquid ring pumps, the system may feature total, partial or no recuperation of the sealing liquid.


Our scope of supply includes piping, valves and all the ancillary instrumentation to achieve total system control. Electric or vapor tracing options are also available. We comply with the technical requisites of engineering contractors and final users.


Applications: Solvents, naphta recovery in chemical and petrochemical industries as well as condenser assistance in combined cycle stations, among others.

GRAHAM CORPORATION

We represent an international leader in the design and fabrication of vacuum systems, with references in the main Refining Companies around the world and the contractors catering to them: PEMEX, SHELL, BP OIL, TECNICAS REUNIDAS, ARAMCO, REPSOL-YPF, CEPSA, FOSTER WHEELER and many others.

Design versatility is our key feature: we adapt to the codes and standards required by each individual project.

Fabrication is done exclusively in own shops with state of the art machinery and highly qualified personnel.

GRAHAM has welders homologated against ASME (including Section VIII Division 1), NAVSHIPS, Canadian MCCR and other special codes.

Highest quality controls are applied in the engineering, design and fabrication processes up to shop tests. X-ray, dye penetrant liquid and mass spectrography leak detection systems are available in house.

We are specialists in systems for vacuum columns some of which are in operation now for over 30 years. Furthermore, our range of products includes: plate exchangers and water heaters.

TUTHILL VACUUM

We have the full range of vacuum pumps: liquid ring Kinney, dry screw, rotating piston, positive displacement blowers for gases and air, boosters and oil free liquid ring. We provide complete skid mounted systems. Our range goes up to vacuum pressures of 0.0003 mm Hg.

KINNEY VACUUM PUMPS

Rotating piston pumps: their design minimizes vibrations and achieves silent operation. In oil free configuration these pumps go up to 0.0002 mm Hg.

Liquid ring pumps: adequate solution for the pumping of wet (including liquid traces) materials. Ample metallurgy.

Blade pumps: A cost effective solution for applications where the process is fairly clean or filtered. Gas control valves are included as standard in steam applications.

Dry pumps: screw pumps operating without sealing liquid in the pumping chamber. Main advantage: wear in the chamber is greatly reduced.

LIQUID RING COMPRESSORS

Capacities up to 15,290 m3/h and discharge pressures over 2.4 barg or greater. Custom tailored design and fabrication.

LOBE BLOWERS (BI AND TRI LOBE)

Essentially noise free blowers for air and process gases. This equipment has multiple applications from mechanical convection to sludge agitation, residual waters, pulps, fluid bed, etc. One main application is the aeration of biogas digestors. Our range goes from 10 m3/h to 16000 m3/h. High capacity boosters (vacuum up to 66 mbar) for all types of vacuum pumps. Packaged blowers with standard or customized acoustic enclosure.
