475-3010

The Pump is a chemically resistant, diaphragm operated, variable flow unit
designed for efficient vacuum, pressure, or gas circulating applications. An
integral fan keeps the pump head cool; the temperature of your service
should remain stable.

470-5942

The Pump is teamed up with a Vacuum/Pressure Control Station to provide
easy, convenient regulation of vacuum or pressure .These adjustments can
be made while the pump is running. The system is portable enough for
benchtop laboratory use, plus many commercial applications where relia­bility and optimum chemical resistance are required.

(3) Storage Procedure

If the system will not be in service for any appreciable length of time,
store it in a clean, dry space. Cover any open ports to prevent entry of
dust.Wipe the pow er cord with a dry cloth and inspect for crac ks in the
insulation. Repair any defects or replace the cord before reusing the
pump.

WARNING: Do not modify the plug. And do not connect the grounding

wire to either of the flat blade terminals. (Grounding wire
is green, sometimes with yellow stripes.)

(1) How to Clean Regulation Valves

DANGER: Unplug power cord before any cleaning operation is started.

The PRESSURE ADJUST and VACUUM ADJUST valves should be
occasionally inspected and cleaned.

• Remove the valve elements by turning the adjustment screws CCW.
Use a cotton swab or clean cloth to clean out dirt or grit around the
venting holes.

• Remove BALL and SPRING. Clean the areas around valve seating
surfaces in the VALVE BODY and elements.

• Reassemble VACUUM ADJUST and PRESSURE ADJUST valves.
IMPORTANT: Note that in the VACUUM valve, the SPRING must

go back in first, followed by the BALL. In the PRESSURE valve, the
BALL must go back in before the SPRING.

(2) Motor Overload Protection

The pump motor has an internal thermal overload switch which may
trip if abnormal operation occurs. If the motor stops, check the pump.
If you find no defect, allow the motor to cool for approximately 30 min­utes, then restart. If the overload trips again—and no external source
causing the overload can be identified—return the complete unit to
your dealer for repair. (Refer to PRODUCT RETURN section at the
end of the manual.)

To Remove the Pump Head

Remove the eight (8) screws holding the pump head to the pump housing.
Do not discard.With the ‘old’head off, examine the diaphr agm f or cr ac ks or
loose particles. Deep cracks would suggest that the diaphragm should be
replaced. Nor mal operation will cause some par ticles to be worn from the
diaphragm. Wipe the diaphragm clean with a dr y cloth or one dampened
with alcohol.If not removed, these particles could affect the perf ormance of
the valves.

To Replace the Diaphragm

Remove the eight (8) screws holding the pump head to the housing. Do
not discard.Slide the diaphragm away from the motor and then lift upward.
Unscrew the bearing collar assembly from the diaphragm. Examine the
bearing; check that the “needles” rotate freely. Install the new diaphragm
onto the bearing collar. Hold the diaphragm center plate, not the rubber
portion of the diaphragm, while the assembly is tightened. Rotate the
eccentric (attached to the motor shaft) by hand while applying grease to the
dowel pin. Use a wooden toothpick or something similar.Don’t scratch the
pin by using a metal object.

To Install the Diaphragm

Rotate the eccentric so that the dowel pin is “upward.” Slide the diaphragm
toward the motor, while gently pushing downward. Align the diaphragm
bead with the groove in the pump housing. It is recommended that a new
pump head be installed whenever a diaphragm is replaced.Excessive wear
particles from the old diaphragm may have entered the valves and
decreased their performance.

To Replace the Pump Head

Position the new pump head so that the flat edge is located toward the
motor.Care should be taken to align the diaphragm bead to the recess in
the pump head before the screws are tightened.Use the original screws to
attach the head onto the housing. IMPORTANT: tighten the screws alter-
nately, at opposite sides of the head, so that it will seat evenly. Use two
steps—first, tighten all to approximately 50 oz-in, then tighten to 100 to 110
oz-in.

CAUTION: Do not disassemble the pump housing from the motor. Proper

assembly (factory adjusted) is critical to proper pump perfor­mance.

SAFETY PRECAUTIONS

DANGERS: Unplug power cord before any cleaning operation is started.

Improper use of grounding plug can result in a risk of electric
shock.

WARNING: Gas under pressure should not be used for supply as a haz-

ardous bursting condition could develop in the pump head.
Use only gases contained at atmospheric pressure.

CAUTION: Do not operate pump when pressure ports of both heads are

in a blocked condition.
