Introduction
The vacuum/pressure pump is a continuously running
constant air flow type unit for use with laboratory
equipment. This vacuum/pressure pump combines
all the advantages of lower pressure pumps with the
perfect uniformity of diaphragm type operation. It
compresses air by means of a long-life diaphragm,
which flexes within the compressor. This pump is
intended for filtration of liquids or gases, or for
other continuous or intermittent use, with all types
of filter holders.
CAUTION: Always use the supplied 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 it.
The pump has these features:
• The motor and pump are permanently lubricated.
• A thermal overload switch with automatic reset
protects the motor.
• Low operating noise is further minimized
by rubber feet.
• All internal surfaces (except the stainless steel
leaf valves) are coated with PTFE polymer, to
prevent corrosion.
• The diaphragm is PTFE-lined to prevent attack by
chemicals or solvent vapors.
• A Millex

The motor is thermally protected and will
automatically restart unexpectedly when
the overload device resets.

Do NOT pump flammable or explosive gases or
vapors or operate this pump in an atmosphere
containing flammable or explosive gases
or vapors.
Use of this pump in a manner not specifically
stated in this user guide may result in severe
bodily injury.
Read and understand the information in this owner's
manual before operating the vacuum/pressure pump.
• The vacuum/pressure pump should be operated in a
dry, clean, and well ventilated area.
NOTE: To ensure proper cooling, the
vacuum/pressure pump cooling fan must not be
blocked and should be a minimum of 1 in. (2.5 cm)
away from any wall or obstruction.
• When the unit is not in use, wrap the power cord
around the vacuum/pressure pump and store in a
dry place. Do not abuse the cord.
• Replace the Millex
if necessary.
• Inspect hose, plug, and cord for signs of damage
before use. Do not use if a deficiency is found.
Never operate a damaged unit. For replacement
parts, see Technical Assistance section for details.
• This vacuum/pressure pump needs no lubrication.
Applying oil to any part may result in polluted air
delivery to the air-handling equipment and will
damage the pump.
• To operate at maximum efficiency, the pump system
must be thoroughly clean. Refer to the Maintenance
section for details on properly cleaning the pump.
• Compressed air blast must never be aimed
at anyone because it can cause serious injury.
Keep children away.
