Introduction
The high output vacuum/pressure pump is a
continuously-running constant air-flow type unit for
use with laboratory equipment. This vacuum/pressure
pump combines the quietness and durability of a
diaphragm pump with the performance of a piston-type
pump. It compresses air by means of a motor-driven
piston. This pump is intended for filtration of liquids or
for other continuous or intermittent uses, with all types
of filter holders, multi-well devices, manifolds, and
other laboratory equipment.
CAUTION: Always use the supplied hydrophobic vent
filter or a vacuum-flask water trap in conjunction with
the pump, as indicated in Figures 1 and 2. Never pump
or draw liquids through the pump, as this will damage
the pump.
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.
• A Millex

hydrophobic vent filter and
27 in. (69 cm) of
1
⁄4 in. (6 mm) I.D. vacuum tubing
are supplied with the pump.
Rules for Safe Operation
Y
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.
• 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
®
-FA
50
vent filter (SLFA05010)
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.
• All vacuum/pressure pumps generate heat, even
under normal operating conditions. To avoid serious
burns, never touch the head parts or tubing during
and immediately after operation.
• When filtering acids, bases, or organic vapors or
gases, use the Chemical Duty Vacuum/Pressure
Pump (WP6111560, WP6122050, WP6110060).
