DOW CORNING SILICONE DIFFUSION PUMP OILS
Dow Corning silicone oils are
designed for fast pumping of large volumes of gas or vapour in high vacuum production
operations.
Performance advantages compared
to other diffusion pump oils:
- Shorter conditioning runs/faster
pumping speeds than organic fluids
- Minimal backstreaming
- Longer service life, resistance to
deterioration or contamination
- Cleaner systems and less required
maintenance because of low migration rates and resistance to breakdown or decomposition.
- Faster cycling, reduced downtime, and
less frequent fluid replacement because the recovery rate after exposure to air at
operating temperatures is much faster than that of organic fluids.
- Resistance to oxidation and
hydrolysis by water vapour.
- Resistance to radiation.
- Full compatibility with rubber seals.
Value advantages:
Dymar Chemicals is the lowest cost in-Canada source for the Dow Corning diffusion pump
oils and high vacuum grease we are price competitive compared to inferior-quality
clone products from other sources.
We inventory for fast and friendly
service, and eliminate the hassles of outside-Canada ordering.
Our fluid recycling
program provides a substantial savings for you through a reduction in new oil purchases
and oil disposal costs. |

Dymars
fluid recycling program:
Reduce your operating costs by
recycling reduce new oil purchases and oil disposal, and achieve better vacuum
performance by using clean, rejuvenated oil instead of deteriorated product. The recycled
fluid can be confidently reused as a direct replacement for new all depleted oil
components/additives are fully restored.. 40 lbs/ 5 (U.S.) Gallons of Dow Corning or a
competitive equivalent is the minimum amount required for recycling, but Dymars
fluid purchase program serves the smaller volume user through our collection of smaller
oil quantities. The pre-recycling condition of the oil determines its value.
Advantages to recycling through Dymar:
Complete lab testing of the
recycled oil. Fast turnaround time, cheaper recycling costs, and fewer shipping and
customs hassles. The fluid returned is of consistently high quality and performance. |
