Vacuum piston pump Saurus 939

Saurus 939 can intake both the vapours of common solvents (methyl alcohol, ethylic alcohol, chloroform, acetone, ethyl acetate, methyl chloride, benzene, toluene, isopropyl alcohol, ethyl ether, heptane) as well as those of more aggressive solvents (hydrochloric acid, acetic acid, chlorobenzene, dimethylformamide, acrylonitrile, dichloroethane, cyclohexane, pyridine, dimethyl sulfoxide, dichloromethane).

Saurus939 is equipped with the exclusive LubriZero system that ensures best possible performance with truly negligible oil consumption, completely compatible with the environment.

The LubriZero system combines the metered injection of oil with a kit of new materials in PTFE with special charges that are not only resistant to corrosion, but require virtually no lubrication. This also allows for the use of synthetic FDA approved oils.

The metered flow of a few drops of fresh oil (about 10 g/h) guarantees an effective barrier from even the most aggressive solvents, considerably increasing the duration of the perfect cylinder-piston coupling and hence the working life of the vacuum pump.

Saurus939 pump guarantees maximum safety throughout the whole process and complete purity of the final product.

In fact, during the entire work cycle, not even one molecule of oil reaches the processed product. This is certified by the Department of Material Science and Chemical Engineering at the Politecnico of Torino, as part of specific research carried out on a complete process of vacuum drying.

The final product is absolutely pure with no risk of oil contamination in the process.

Better quality is never an expense: it’s an investment. And investment is always rewarded with good results. Over time the Saurus939 vacuum pump, achieves more, lasts longer and has lower running costs with respect to other main technologies for vacuum systems.

The use of oil not only avoids any contamination in the process, but also improves performance and increases pump life, reducing maintenance costs, even in the presence of very aggressive solvents. The choice of materials, technology employed and the appropriate solutions taken by Italvacuum in every design detail make Saurus939 the best in the sector, with reliability and results beyond comparison.

-        Lower operating costs than any other vacuum technology;

-        LubriZero system with negligible oil consumption;

-        Extremely limited environmental costs;

-        Low-energy motors;

-        Easy and economical maintenance;

-        Absence of warm-up cycles and waiting times;

-        Physical separation between process and mechanical parts;

-        Low noise (<70db) and low operating speed (250 rpm);

-        Low average working temperatures;

-        ATEX certification up to zone 0.

Cooling is by air.

Saurus939 has two completely separate, independent lubrication circuits:

-        one circuit for the process part, with metered injection of fresh oil, thanks to the LubriZero system,

-        one circuit for the mechanical part with recirculated oil.

Cylinder, pistons, piston rings and head are made of special anti-acid cast iron. The other components are made of cast iron, special steel and PTFE with special charges. The pump is completely sealed: a characteristic that makes it extremely reliable and efficient for a long time, even in damp and dusty environments.

The discharge valves have automatic openings and are available in different materials, including Hastelloy.

The high quality of Saurus939, not only in the unquestionable reliability of the vacuum pump, but also the wide range of accessories, allows for turn-key installation of the entire vacuum group:

1. Atmospheric post-condenser for the recovery of solvents from the pump outlet

2. Condensate recovery tank from the post-condenser outlet

3. Pump suction filter with particle centrifuge separation and metal filtering cartridge

4. Control panel board, also available in compliance with ATEX DIRECTIVE 94/9/EC

5. Support base for easy, fast installation.

Saurus939 complies with the requirements of the most demanding European Directives:

• MACHINERY DIRECTIVE 2006/42/EC

• ELECTROMAGNETIC COMPATIBILITY DIRECTIVE 2004/108/EC

• ATEX DIRECTIVE 94/9/EC.

The standard version, CE εx II 2G T4/T3, is suitable for installation in an area classified as ZONE 1-GAS and temperature class T4 (135°C).

The Saurus939 special version can be supplied with ATEX certification up to ZONE 0-GAS (internal pump), ZONE 1-GAS (external pump) with three different classes of temperature T4 / T150°C / T3.
