Please note that the technical data stated are only typical data. Slight variations from batch to batch must be expected.<br />
The technical data stated here can not be taken as assured properties<br />
1) GS 32 is more suitable for SOGEVAC SV 25 B and smaller, where its lower viscosity helps to maximise starting performance.<br />
GS 77 is more suitable for SOGEVAC SV 40 B and larger, where its higher viscosity helps to to reach the lowest pressure.<br />
However, all SOGEVAC pumps can operate with either oil, and GS 32 and GS 77 are mixable with each other.<br />
2) Compatibility depends on the amount of acrylonitrile in the NBR<br />
