ATR "C" version: protected
for corrosive gas pumping
inverted dynamic seal: an additional protection
anti-corrosive protection is a built-in mechanical system based on
the molecular drag pump principle.
The inverted dynamic
seal provides a high compression ratio between the bearings and the
pump exhaust and minimises the amount of corrosive gases reaching
Protected against the corrosion
The ATP pumps of the
"C" version are well adapted to corrosive gas pumping. The gas
purge added to the inverted dynamic seal result in an enhanced
protection against corrosion.
