Technical data
a.)
Partial vacuum of permanent gases measured at pump inlet.
b.)
The total vacuum, e.g. measured with thermal-conductivity vacuummeter, is higher than the partial vacuum because the
former includes the vapour pressure of the pump oil and other condensable vapours (e.g. water); the condition of the
oil (cleanliness, content of hydrocarbons with higher partial pressures) is crucial for this value.
c.)
The maximum inlet pressure for water vapour, or rather the maximum inlet pressure for vapour, cannot be specified in
accordance with PNEUROP because it cannot be determined for the HYBRID pump in accordance with this standard.
On account of the considerably reduced pressure in the oil-sealed part of the RC 5, however, the value is considerably
higher than that of a conventional oil-sealed rotary-vane pump.
d.)
With inlet sealed and without gas ballast.
e.)
Oil temperature and pressure in the oil reservoir are the relevant parameters for maximum inlet pressure for vapours and
chemical resistance.
