SP201 (HIGH FLASHPOINT)

VAPOUR BOOSTER PUMP OIL

This special product has been developed to be a high flashpoint alternative to DP201 or AP201.

SP201 was developed for customers who have the need for increased safety features in stressed environmental operating conditions.

It can offer up to 5 times the lifetime of normal oils therefore reducing plant maintainanace costs and down time, as well as increased safety features.

SILICONE OIL’S FOR DIFFUSION PUMPS

Phenyl-Methyl Silicone fluids have a proven reliability as a medium for the production of high vacuum with fast pumping speeds.

coupled with outstanding resistance to oxidation. Silicone 704 and 705 are linear chain compounds, and Silicone 702, 737 and 747 are cyclic silicone ring compounds with variable size rings and Methyl to Phenyl ratio’s. Colour ranges from water white to a light straw yellow tint on all silicone oils.

SILICONE 705

DIFFUSION PUMP OIL

A complete drop in replacement for Dow Corning™ DC705 or Wacker AN 175.

Saturated Vapour Pressure at 25˚C 3.0 x 10-10mbar.

WE CAN SUPPLY THIS PRODUCT IN SMALL BOTTLES FOR LAB USERS OR LARGE AMOUNTS FOR INDUSTRIAL USERS – ASK FOR DETAILS.

Envoil 20

Diffusion & mechanical pumps

Saturated Vapour Pressure at 25˚C 8.0 x 10-8mbar. Can be used to substitute Invoil 20

A cost effective hydrocarbon diffusion pump fluid well suited for applications where excessive contamination requires frequent fluid changes.

Envoil 20’s relatively low boiling point enables high dynamic pumping speeds to be attained in processes where gross rates of outgassing are experienced.

SATTORLENE NORMAL

Diffusion Pump Oil.

May be used as replacement for Leybold™ Diffelen Normal. Saturated Vapour Pressure at 25˚C 3.2 x 10-8mbar. Ultimate Pressure LN2 1.5 x 10-9mbar.

A thermally stable water white Hydrocarbon oil having a lower saturated vapour pressure verses viscosity slope when compared with other Diffusion Pump Oils.

The low molecular weight distribution results in high dynamic pumping speeds and low backing line temperatures.

Satorrlene Light

Diffusion Pump Oil.

As Satorrlene Normal but having a higher Saturated Vapour Pressure. Saturated Vapour Pressure at 25˚C 8.0 x 10-8mbar. Ultimate Pressure LN2 1.8 x 10-8mbar.

THIS PRODUCT HAS BEEN replaced BY SATORrLENE NORMAL.

DP201

Vapour Booster Pump Fluid.

Derived from a first class hydrocarbon starting material, and protected against air abuse by an anti-oxidant of matched vapour pressure.

Principally used for the processing of high grade steels and alloys. Saturated Vapour Pressure at 25˚C 5.0 x 10-6mbar. May be used instead of Apeizon™ AP201.
