Introduction
The Millivac Maxi Diaphragm Pump is a double-head, dry-running de-
vice used in a wide range of laboratory applications including those
that require pumping slightly aggressive or corrosive gases and vapors.
This pump works without oil lubrication, eliminating oil vapors that
might pollute the transferred, evacuated or compressed air. The design
of this small pump includes a patented diaphragm for maintenance-
free service for a minimum of one year. The design is also gastight
with a leakage rate of approximately 6 × 10
-3
mbar × l/s.
CAUTION:
Always use a hydrophobic vent filter or a vacuum-flask
water trap in conjunction with the pump. (See Figures 1
and 2.) Never pump or draw liquids through the pump, as
this will damage the pump.
