3.1

Design

The diaphragm pump consists of a pump housing
and a drive motor.
The pump casing contains the drive unit and two
four pump heads. Each pump head contains a dia-
phragm and the work valves. Two pairs of pump
heads are arranged opposite each other. 1 to 4
stage pumps are supplied, depending upon the cir-
cuitry of the pump heads.
The pump heads are driven via an eccentric shaft
with a connecting rod.

Areas of Application

ILMVAC Diaphragm Pumps are intended for:
• Pumping and compressing neutral and aggressive gases and vapours.
• Generating a vacuum down to an ultimate pressure < 1 mbar.
• Use in physical and chemical laboratories in trade and industry.
• Use for vacuum filtration, vacuum distillation and vacuum drying, and other vacuum tech-
nology applications.
3.3

Principle of Operation

Motor, eccentric shaft and connecting rod set the diaphragms in stroke movement. This
changes the size of the space between the diaphragms and pump head (pump chamber).
Increasing the size of the pump chamber opens the inlet valve while the outlet valve is
closed (intake process).
Decreasing the size of the pump chamber ejects the gas through the outlet valve.
The valves are actuated by the gas being pumped. A large proportion of fluid in the dia-
phragm pump minimizes the pumping efficiency.
