- Operating instructions.
Diaphragm vacuum pumps (also called membrane pumps)
are oscillating positive displacement pumps. The dia-
phragms generate vacuum by expanding the volume in the
vacuum chamber which in turn reduces the pressure in the
vacuum chamber thus causing atmospheric pressure air to
be pushed into the chamber. The air in this chamber is then
pushed out from the vacuum chamber through a different
route (gas outlet) with the use of valves. These periodic
movements of the diaphragm generates vacuum at the in-
let of the pump.
Attention have to be paid when working with gas mixtures
containing condensable gases, e.g. water vapour or sol-
vents. Use of

with these gases will
result in their condensing somewhere in the air flow of the
pump. This causes pressure build up in the vacuum chamber
which in turn reduces the service life of the diaphragms and
valves.
Useful information
To prevent condensation or to discharge condensates pro-
duced by the pump, the gas ballast valve should be opened.
By opening the gas ballast valve, a small amount of air is
allowed into the vacuum chamber, reducing the concentra-
tion of the condensable gas. Purging of condensation can
also be done by allowing full gas flow at atmospheric pres-
sure through the pump for several minutes.
To protect the internal valves and diaphragms, fit an up-
stream condensation trap (such as a Woulff bottle) to the

and

).
The release of solvent vapors into the atmosphere can be
avoided by fitting a downstream discharge condensation
trap.
The exhaust air hose should generally deliver to a laboratory
extraction system.
Fitting an exhaust air hose will also reduce the noise level.
