pumps can transfer air as well as neutral or
aggressive gases at temperatures up to 240 °C.
In order to prevent condensation of the measuring
gas, the heated head pump types possess temperature-resistant
pump head components and optional thermostatic
or electronic temperature control.
temperature-resistant and heated diaphragm vacuum
pumps from KNF are based on a simple principal
- an elastic diaphragm, ixed on its edge, moves
up and down its central point by means of an
eccentric. In this way the medium is transferred
using automatic valves.

240 °C without a heater (for diaphragm gas
pumps with pump head heater, see data sheet
is a choice of pump drives ranging from a selection
of AC motors to explosion-proof models.

pumps have become the standard in many analytical
applications. Based on their design, they work
without any lubrication.
hot gases need to be analyzed, and the gas must
not be allowed to cool down when it is transferred
from the source being checked, to the analyzer
as the constituent parts could condense out,
leading to faulty results. To overcome these
problems hot gases are pumped using diaphragm
pumps with temperatureresistant pump head.
