SAFETY PRECAUTIONS
CAUTION: Use only pre-formed MASTERFLEX
®
L/S
®
PTFE tub-
ing. Use of other tubing may result in premature or
unknown failure modes.
WARNINGS: Turn drive off before removing or installing tubing.Fin-
gers or loose clothing could be caught in the rollers.
Use recommended fittings only. Use of improper fit-
tings and/or improper connection to fittings may re-
sult in leakage at the fittings.
Do not operate the pump without the following pre-
cautions:
Either of the following two conditions can result in
sudden and/or extensive tubing failure.Tubing failure
may result in liquid leaking from pump. In the event of
tubing failure, operating pump at elevated speeds and
pressures will result in accelerated liquid leakage. Use
appropriate measures to protect operator and equip-
ment from caustic liquids.
1. HIGH PUMP-generated pressures.
A PRESSURE RELIEF/BYPASS VALVE must always
be installed in a potentially high pressure system
to prevent the pump from exceeding the maximum
rated pressure (100 psig;6.8 bar).
a. where the possibility of a blocked outlet occurs.
b. where occlusion setting is greater than recom-
mended.
c. where higher pressure filters are used that do
not have a built-in pressure relief system.
2. HIGH SYSTEM-generated backpressures.
AN INJECTION CHECK/BACK PRESSURE VALVE
should always be installed when pumping into a
pressurized reservoir or line. This will prevent
siphoning and/or backflow of liquid from a treated
line in the event of tubing failure.

APPLICATION DATA
The Model 77390-00 PTFE Tubing Pump is used to pump caustic and/or
sterile liquids, particularly those liquids that are not compatible with other
existing MASTERFLEX tubing materials. The use of PTFE tubing provides
improvedliquidcompatibilityandmaintenanceofliquidpurity.Thespecially
designed tubing assemblies provide for intermittent operation at pressures
upto100psig.VariouscompatibleaccessoriesareavailableincludingPTFE
valves, T-connectors, fittings, etc. for connection to remaining user system
components.Makesurethatthefittingsusedareproperlysizedandare
compatible with the pressure rating of the pump. Contact your dealer.
A typical application is transfer of liquids from storage containers to those
usedinexperiments.Meteringofsuchliquidsisanotherapplicationwhenthe
pump is used with an appropriate MASTERFLEX®L/S®Pump Drive. The
higher pressure capability allows use in low-volume filtering, chromatogra-
phy sample injection and other applications.
GENERAL DESCRIPTION
ThePTFETubingPump(seeFigure1)iscomposedofaBodyAssemblyand
anadjustableOcclusionBed.TheBodyAssemblyisusedtoattachthepump
to a drive and to support the six-roller ball bearing Rotor Assembly and the
OcclusionBed.TheOcclusionBedholdsthetubingandmountstotheBody
Assembly. It is held in place by increasing the occlusion to an appropriate
level. Occlusion is controlled by adjustment of the Occlusion Adjustment
Knob.ALockingRingmaintainstheocclusionsetting.Thesix-rollerconfigu-
ration provides low pulsation and prevents back-flow when the pump is
stopped.
Tubingisheldinplacewithouttheuseofspecialretainers.Thecurvature of
the groove along the lower surface of the Occlusion Bed matches the curve
of the tubing assembly and holds the tubing in place during pumping.
Two different diameter specially fabricated PTFE tubing assemblies are
available. The tubing is semi-flexible and chemically inert.

INSTALLATION
Mounting the Pump Head to a MASTERFLEX®L/S®Pump Drive
The Pump Head is attached to the drive unit with four supplied screws as
shown in Figure 2.
NOTE: TwoTangBootsareprovided. The Pump Headisshippedwiththe
closed end Tang Boot (A-3480) installed which matches most
MASTERFLEX®L/S®Drives. Replace with open end Tang Boot
(A-3514) when necessary.
1. Rotate the Occlusion Adjustment Knob fully counterclockwise to lift the
Occlusion Bed as shown in Figure 3.
2. Remove the Occlusion Bed by sliding out thefrontof the Body Assembly.
3. AligntheTangon thePumpHead(including installedboot)withthe slot
in the motor drive shaft.
4. Align the lower mounting holes on the Pump Head with the mounting
holes on the drive and fasten with the two thumbscrews.
5. Insert the two Phillips screws through the mounting holes in the upper
part of the Body Assembly. The upper two screw holes are accessible
by removing the Occlusion Bed.
This completes the mounting of the Pump Head. Proceed with the Setup
Procedure.

5. Slide the occlusion assembly into the front of the body assembly.
WARNING: Use recommended fittings only. Use of improper fit-
tings and/or improper connection to fittings may re-
sult in leakage at the fittings.
6. Attach connecting fitting to the inner PTFE tubing in the Pump Head.
Never attach connecting fitting over the larger of the two concentric
PTFE tubing sections.
WARNINGS: Do not operate the pump without the following precau-
tions:
Either of the following two conditions can result in
sudden and/or extensive tubing failure. Tubing failure
may result in liquid leaking from pump. In the event of
tubing failure, operating pump at elevated speeds and
pressures will result in accelerated liquid leakage. Use
appropriate measures to protect operator and equip-
ment from caustic liquids.
1. HIGH PUMP-generated pressures.
A PRESSURE RELIEF/BYPASS VALVE must always
be installed in a potentially high pressure system to
prevent the pumpfrom exceedingthe maximumrated
pressure (100 psig; 6.8 bar).
a. where the possibility of a blocked outlet occurs.
b. where occlusion setting is greater than recom-
mended.

c. where higher pressure filters are used that do not
have a built-in pressure relief system.
2. HIGH SYSTEM-generated back pressures.
AN INJECTION CHECK/BACK PRESSURE VALVE
should always be installed when pumping into a
pressurized reservoir or line. This will prevent
siphoning and/or backflow of liquid from a treated
line in the event of tubing failure.
NOTE: The following leakage modes are considered evidence of tubing
failures:
1. Drip from exit of the outer tube of the concentric tubing
assembly.
2. Liquid between inner and outer tubes of the tubing
assembly.
3. After pump reaches full prime, a continuous and regular
stream of bubbles exiting the tubing assembly.
User must replace tubing at first sign of such leakage.
Recommended Occlusion Setting
CAUTION: Do not run the pump dry for an extended period of time.
Pumping dry or over-occluding can cause overheating
and pump damage.
Proceed as follows:
1. Dipentryandexitconnectingtubingapproximatelyoneinchintothefluid
to be pumped.
2. Be sure Pump Drive is turned on and set to desired operating speed.
3. Rotate Locking Ring fully counterclockwise. Ring should be against
lower side of Occlusion Adjustment Knob.
4. Slowly rotate Occlusion Adjustment Knob clockwise just until bubbles
firstappearatoutputoftheexitconnectingtube. Roughly ,thiswilloccur
when 1) the top of the Occlusion Bed becomes even with the top of the
Body Assembly, and 2) the pump noise level decreases.
5. Rotate Occlusion Adjustment Knob an additional one-fourth turn clock-
wise.
6. Rotate Locking Ring fully clockwise until it is tight against the top of the
Body Assembly, thus locking the Occlusion Adjustment Knob in place.

Optimized Occlusion Settings
Occlusion is reduced by rotating the Adjustment Knob counterclockwise.
Some applications require adjustment of the occlusion setting to maximize
tubelifewhileothersrequireadjustmenttomaintainflowratewhensubstan-
tial system pressure exists. However, the recommended setting will meet
the requirements of most applications, giving both good tube life and some
pressure capabilities.
To Maximize Tubing Life
Occlude according to recommended setting described above and allow
pump to prime with the fluid to be transferred. Then, while the pump is
running, simply reduce the adjusted occlusion setting by slowly turning the
Occlusion Adjustment Knob until the flow drop-off becomes unacceptable.
