when servicing internal components.
WARNINGS: Tubing breakage may result in fluid being sprayed from
pump. Use appropriate measures to protect operator and equipment.
Turn drive off before removing or installing tubing. Fingers or loose
clothing could get caught in drive mechanism.
WARNINGS: Do not operate the pump drive in a manner not
specified in the documentation. Misuse of the pump drive may result in
a hazard and may compromise the safety protection built into the pump
drive. If the pump drive is damaged, turn it off and not use it until
service-trained personnel can check its safety.
Single-Phase Only. Not to be used with Split-Phase lines.
Main disconnect is accomplished by disconnecting the detachable
power supply cord at the appliance coupler or at the main plug. Ensure
the power cord is easily accessible and removable, in the event of an
emergency, which requires immediate disconnection.
The operator should check the detachable power supply cord condi-
tion. The equipment should not be operated if the power supply cord is
cracked or broken. Any obvious damage to the enclosure (from a drop
or fall) should be checked by service personnel for loose or damaged
parts inside.
CAUTIONS: Power must be disconnected before connecting the
external remote control cable to prevent damage to the drive.
Do not block the rear panel of the pump drive. The power cord must
always be easy to disconnect.
Replace the power cord only with one of the same type and rating.
The power cord set supplied with your pump drive meets the require-
ments of the country where you purchased the pump drive. If you use
the pump drive in another country, you must use a power cord set that
meets the requirements of that country.
When using hazardous chemical and biological agents, take all suit-
able protective measures, such as wearing protective glasses and
gloves resistant to the substances used. Follow local and/or national
regulations for safe operation and maintenance of the system.

• No seals in contact with the medium pumped.
• No valves to clog.
• Inner surfaces are smooth and easy to clean.
• Fluid contacts only the tubing or tube material.
• Suction lift and priming up to 1.5m water column at sea level.
• Low shearing for handling the most shear sensitive of fluids like latex
or fire fighting foam.
• Capable of running dry and pumping fluids with high quantities of
entrained air, such as black liquor soap.
• High volumetric efficiency allows operation in metering or dosing
applications where high accuracy is required.
• Handle extremely viscous fluids.
• Tubing and tube materials are available that are suitable for food and

1-2 MASTERFLEX®Digital Pump Drive Operating Manual Masterflex
Section 1
Introduction
The MASTERFLEX Digital Peristaltic Pump Drive offers flow rate
capacities from 0.00013 mL/min to 324 mL/min depending on model
and tubing being used. Features include a small footprint, plus non-
stainless steel drives that are stackable.
The MASTERFLEX digital pump provides a motor speed repeatability of
+/- 0.1 percent to maximize productivity in precision liquid dosing, batch
dispensing and filling applications. A turndown ratio up to 3000-to-1,
bidirectional flow and self-priming capabilities allow for smooth, seamless
operation and an extremely broad flow range within one tubing size.
In addition to high accuracy, precision, repeatability and resolution
of speed (or flow rate), the MASTERFLEX drive features an intuitive,
man/machine interface with a four-line graphical LCD display providing
direct readout of pump speed (rpm), flow rate (user-selected units),
number of dispenses, and menu options.
The easy-to-use keypad eliminates setpoint overshoot and provides easy
navigation through menu options that include a number of on-screen
programming features.
These drives use high precision, no-maintenance brushless motors for
improved reliability. This, combined with its high turndown, superior
accuracy, and intuitive interface make the MASTERFLEX drives ideally
suited where ultra-precise, repeatable flow control is required. The pump
accommodates a variety of product fill volumes and batch dispensing
profiles, and fluid only contacts the tubing, providing for contamination-
free pumping.
MASTERFLEX pumps are self-priming, can operate dry without damage,
are suitable for most chemicals and contain no valves or seals. See Tubing
Guides within this flash drive or on the web.

Operation
Main Screen e drive has two different modes of operation—Continuous mode and
Copy Dispense mode. e drive also can be controlled directly via the
control panel or remotely through input signals to the 25-pin connector
on the back panel of the drive. Several primary control functions
including starting and stopping the pump, adjusting the rpm/flow rate,
and changing pump direction can be performed independently via use of
the control panel or through the remote control. is is true for both
Continuous and Copy Dispense modes (see the Remote Control section
following for more details).
CONTINUOUS MODE is the default pumping mode. e pump
will operate continuously at the set rpm (or flow rate) unless the drive is
either stopped or the flow rate/rpm is changed by the user. Refer to
Continuous Mode in this manual.
COPY DISPENSE MODE allows for dispensing at specific
volume intervals. (Example…repetitively filling vials with the same
volume by a single press of a button, foot switch or dispensing
wand.) Each dispense can be started either via the Enter Key
on the control panel or through the Start/Stop contact on the back
of the drive (see Remote Control section following). e Off Time feature
further allows for a continuous dispensing pattern by which a specific
off time interval between each dispense can be set. us a continuous
Dispense-Off Time-Dispense- Off Time cycle is created. An additional
feature of the Copy Dispense mode is Batch Count (0000/0015). is allows
you to set a limit to the number of dispenses the pump will deliver before
stopping. Once the count limit is achieved, the batch count will have to be
reset to zero to continue pumping. Please note that batch count can be set
to infinity ( ) to allow for continuous dispense cycling. Refer to Copy
Dispense Mode in this manual.
