1.1 Description

The peristaltic pump motor offers microprocessor control and a digital display,
and is designed to be fully compatible with our peristaltic pump. No mounting
plate is needed, just two mounting screws. A

1

⁄10 HP (75W) motor provides flow
rates of up to 2280 mL/minute. A convenient membrane keypad lets you enter
values and control all pump operations. A dot matrix LCD provides for easy
view. Calibrating the unit is easy with the user-friendly control software.
Simply select a tubing size and the desired flow rate, and the pump motor locks
in the required RPM. Select nominal calibration values stored in ROM (read
only memory) or calibrate via gravimetric measurements. Fluid temperature
may be displayed (using an optional Type K thermocouple probe). The last
motor settings are stored in memory when the drives are shut off.

The peristaltic pump motor provides you with four different modes of pumping:

• The RPM Mode for pumping at a certain RPM setting for

an unlimited period of time

• The FLOW RATE Mode for pumping at a certain FLOW RATE

setting for an unlimited period of time

• The TIME Mode for pumping at a certain RPM or FLOW

RATE setting for a specific period of time

• The TOTAL VOLUME Mode for pumping at a certain RPM or FLOW

RATE setting to dispense a specific amount
of fluid

The pump is available in two versions: 110Vac and 220Vac.

1.2 Features

• Digital Display of Flow Rate, RPM, Total Volume, Fluid Temperature (°C or
°F), Flow Duration, or Tube ID

3.2 Selecting Tubing

Select a tubing material and size that is right for your application (the fluid and
flow rate that you are pumping).

Table 9-2 in Chapter 9, shows the average flow rates for different size tubing.
Normalized flow rates (mL per revolution) vary significantly, based on motor
speed, tubing materials, viscosity, and mechanical tolerances in pump dimensions.
Table 9-3 outlines the variances resulting from differences in motor speed, tubing
materials, and mechanical tolerances. Table 9-6 outlines the variances due to
differences in viscosity.

To determine the chemical compatibility of a particular tubing material, it is
recommended that you test the tubing under actual conditions.

Tubing materials that can be used include Vinyl, Viton, Tygon, Silicone,
Santoprene, and Norprene. Up to 68 durometer tubing can be used.

Poor tubing life results were obtained for 5⁄16" (8.0mm) inner diameter
Santoprene tubing. This particular tubing should not be used with the
pump motor.

3.3 Tubing Life

Over time and high speeds, flow rates will drop as the tubing wears out. Tubing
life for various materials and sizes are shown in Table 9-4 in Chapter 9. Tubing
should be periodically inspected for wear. Either move the tubing to a fresh
section, or replace tubing entirely (refer to Section 3.4).

3.4 Loading the Tubing

Perform ALL of the steps in Chapter 3 before turning the motor on.

Follow this procedure (refer to Figures 3-8 through 3-12):

Figure 3-11. Closing the Stator Figure 3-12. Adjusting the Clamp Screw

1. Refer to Figure 3-8 and Figure 3-9. Snap open the Stator by pushing the
spring-loaded area of the Latch. Remove any old tubing from the pump, if
necessary.

2. Refer to Figure 3-8 and Figure 3-10. Loop the Tubing over the rollers. This is
easy to do even for stacked pumps.

Tubing can be changed on stacked pumps without detaching either of the
pumps from the motor.

3. Refer to Figure 3-11. Push the Stator closed until you hear the Latch engage.

4. Refer to Figure 3-12. Tighten the Clamp Screw until the Clamp Plate contacts
the Tubing, securing it in place.

5. Set up the source and drain containers so that the tubing inlet is immersed in the
fluid in the source container and the tubing outlet is in the drain container.

See Section 5.2 to set the pumping direction.

4.2 Using the ON/OFF Switch

When the ON/OFF switch is pushed upwards the unit’s power is on. When the
switch is pushed downward, the unit’s power is off and the top of the switch
labeled “0” is visible.

4.3 The STOPPED Display Mode

To enter the STOPPED Display Mode, do the following:

1. Plug in the pump motor to a convenient ac wall outlet. Use ac power within the
range of 90 to 130 Vac (for 115 Vac units) or 190 to 260 Vac (for 220 Vac
units).

A line filter is already installed in the pump motor.

2. Attach the pump(s). Refer to Section 3.1.

5.2 Defining the Direction of Pumping

The INLET SELECT key, left and right pump icons, and green LEDs define the
direction of pumping by specifying the tubing inlets and outlets.

1. Refer to Figure 5-1.

2. To determine the direction of pumping, look at the left and right pump icons and
green LEDs. Only one of each pair of LEDs is lit. The lit LED points to the tubing
inlet.

A top tubing inlet on the left pump corresponds to a bottom tubing
inlet on the right pump and vice versa.

Two pumps stacked on one side of the motor will pump fluid in the same
direction. Two pumps mounted on opposite sides of the motor will pump
fluid in opposing directions.

5.4 Priming the Tubing

Pressing the PRIME key causes the tubing to fill with fluid.

1. To prime the tubing, press and hold down the PRIME key. As long as you hold
down the PRIME key, fluid flows in the tubing, and the display shows
“Priming...”.

2. To stop priming a tube, simply release the PRIME key. The pump motor stops
running, and fluid stops flowing.

Extensive testing has shown that the minimum motor speed required to prime
the tubing varies significantly with the size of the tubing. These variances are
shown in Table 9-3 in Chapter 9. If the tubing will not prime regardless of motor
speed, simply press on the pump stator (refer to Figure 3-11) while the stator is
shut and the motor is running. Pressing on the stator enhances the priming
action of the pump. Release pressure after the tubing is primed.

Since tubes of different materials, sizes, ages, and durometers produce different
flow rates, the CALIBRATE key allows you to calibrate each piece of tubing you
use. Calibration accuracy data is shown in Table 9-1 in Chapter 9. Once the
tubing is calibrated, you no longer need to be concerned about flow rate
variances outlines in Table 9-3.

Along with the usual pumping equipment (pump(s), pump motor), you will
need calibrated beakers or cylinders to function as source and drain
containers.

1. Before you initiate the calibration process, you must set the pump up for
pumping in the same direction as you plan to use during normal pump
operation (refer to Section 5.2). In addition, make sure the display shows
STOPPED Display Mode (the motor is not running).

2. Set either the RPM or FLOW RATE setting of the pump motor:
2a. To set the RPM, press the RPM key. The display flashes the current RPM

setting (xxx rpm). Use the UP and DOWN ARROW keys to adjust the
setting.

2b. To set the FLOW RATE, press the TUBE ID key and use the UP and DOWN

ARROW keys to select the inner diameter of the tube you are using. Press
the FLOW RATE key. Use the UP and DOWN ARROW keys to adjust the
setting.

3. When the display shows the RPM or FLOW RATE setting you desire, you are
ready to initiate the calibration process.

4. Press the CALIBRATE key. The display should flash and show, “Prime or
START ?”.

5. To prime the tube, press and hold down the PRIME key. As long as you hold
down the PRIME key, fluid flows in the tube, and the display shows,
“Priming...”.

6. When fluid has completely filled the tube, simply release the PRIME key. The
pump motor stops running, and fluid stops flowing.

7. To dispense fluid for calibration, hold the tubing outlet over the drain container
and press the START/STOP key. Fluid flows, and the display enters the Running
Display Mode, showing the message, “Dispensing...”.

8. When you have allowed fluid to dispense for a minute or two, press the
START/STOP key to stop the pump. Fluid stops dispensing, and the display
returns to the STOPPED Display Mode. The display momentarily flashes the
message, “Enter TOTAL VOL.” and then flashes the total volume dispensed (xxx
ml or xxx Liters) alternating with the message “Start or CAL ?”.

9. To continue to dispense fluid, press the START/STOP key again. Fluid flows,
and the display returns to the Running Display Mode, showing the message,
“Dispensing...”.

Operating the Pump Motor in the STOPPED Display Mode

5-7

NOTE

10. After you have finished dispensing, press the START/STOP key to stop the pump
motor. Then measure the dispensed fluid’s volume using your calibrated beaker.

11. When you have determined the volume of the dispensed fluid, use the UP and
DOWN ARROW keys to enter this volume on the display.

12. Once the display shows the correct volume of fluid dispensed, press the
CALIBRATE key to complete the calibration. The display flashes and shows,
“CALIBRATED!”, and the red LED next to the CALIBRATE key lights up.

13. Now you can select a mode (RPM, FLOW RATE, TIME or TOTAL VOLUME)
(refer to Chapter 6). Once started, the fluid will be pumped according to the
calibration.

If you replace your tubing, make sure to press the TUBE ID key and select a
different tube id size using the UP or DOWN ARROW keys.

You can independently calibrate only one pump at a time. If
you have two pumps attached to the motor (even if they are stacked), only
one of the pumps can be calibrated.

For optimum FLOW RATE or TOTAL VOLUME accuracy, you will need to
recalibrate the tubing as a result of:

•

Using a different tube size (inner diameter)

•

Using a different tubing material

•

Using a tube of a different age (calibration should be checked

every 5-10 hours.)

•

Using a different back pressure in the tube

•

Changing the fluid being pumped

•

Changing the fluid’s temperature or density

•

Changing the RPM or FLOW RATE setting

•

Reversing the direction of pumping

•

Changing the clamp screw adjustment of the pump(s)

TIPS FOR OPTIMUM CALIBRATION ACCURACY:

Presented below are three useful techniques that will help you obtain optimum
calibration accuracy.

•Calibrate the unit at the speed you plan to use for normal pump operation.

• When dispensing fluid during calibration, allow the pump to dispense the
largest total volume that your measurement equipment supports.

• When measuring the dispensed fluid during calibration, calculate the
volume by measuring the fluid's mass with an accurate gram scale and
dividing this mass by the fluid's density.

Operating the Pump Motor in the STOPPED Display Mode

5.6 Measuring the Temperature of a Fluid

The TEMP key displays the temperature of the fluid, as measured via an optional
Type K thermocouple probe. The pump motor is equipped with an SMP Type K
female thermocouple jack, located near the bottom on the back of the pump
motor.

1. To measure the temperature of the fluid, plug one end of an optional Type K
thermocouple probe (equipped with an SMP male connector) into the SMP jack
and immerse the other end of the probe in the fluid.

2. Press the TEMP key. The display shows the fluid’s temperature in (°F or °C).

3. If you are reading the temperature in °F and wish to switch to °C (or if you are
reading the temperature in °C and wish to switch to °F), press the TEMP key
again. The display shows the fluid's temperature in the unit of measure to
which you switched.

If the optional thermocouple probe is not connected to the pump motor, the
reading on the display will be 300°F (149°C).

5.7 Preparing for Pumping in a Specific Mode

There are four specific modes in which to pump fluid: RPM, FLOW RATE,
TIME, and TOTAL VOLUME. These modes correspond to the criteria the pump
motor uses to dispense the fluid. These four modes are described on the next
page.

When you press the START/STOP key and the pump starts running, the
active pumping mode is the last mode displayed before you pressed the
START/STOP key.

Detailed instructions on how to select a pumping mode and adjusting the
settings in that mode appear in Chapter 6.

6.5 Preventing Tubing from Moving During Pump Operation

Once you start the pump, you may need to adjust the Clamp Screw slightly, to
prevent the tube from creeping (moving) through the pump. Creeping tends to
occur on tubing of larger sizes and tubing made from low friction materials (for
example, Santoprene). Use the following procedure to eliminate creeping. Refer
to Figure 6-9.

Figure 6-9. Adjusting the Clamp Screw

1. Press the START/STOP key to stop the pump (motor).

2. Rotate the Clamp Screw a quarter turn clockwise, in order to increase the
pressure of the Clamp Plate on the tubing.

3. Press the START/STOP key again (to restart the pump). Observe the tubing. If

pumping.

6.6 Other Pumping Options

The pump motor is equipped with two features that allow limited remote control
and monitoring capability. These features are described in Sections 6.6.1 and

6.6.2. The features are independent. Either one or both may be used at any time.

6.6.1 Auxiliary Out (Remote Monitor)

The Auxiliary Out function allows you to remotely monitor whether the pump
motor is running or stopped. The Auxiliary Out terminals are located near the
bottom, on the back of the pump motor, next to the LANGUAGE button. Use the
schematic circuit (Figure 6-10) (Resistor, LED and 9Vdc supply must be user
supplied) to monitor the motor.

8.1 Theory of Operation

The pump motor consists of an electric motor and a pulley assembly controlled
by a microprocessor and circuit board. Driven by ac power, the motor produces
a torque which drives the pulley assembly. The pulley assembly reduces the
motor output speed and drives the pump. All of the pump motor’s functions
are regulated by the microprocessor and circuit board. You enter information to
the motor via a membrane keypad.

8.2 Design Considerations

Customers commonly desire a pump motor that they can calibrate to obtain
accurate flow rates with a wide variety of tubing materials, sizes, and
durometers. They also want the ability to pump fluid from more than one
source container at the same time. In addition, they may need the freedom to
pump fluid in opposing directions at the same time. Customers also desire a
variety of ways by which to pump their fluid. Above all, they want to carry out
all these processes with a user-friendly piece of equipment.

8.3 Design Solution

The peristaltic pump motor satisfies today’s diverse customer needs. Its
sophisticated software allows customers to calibrate the motor for use with a
wide range of tubing materials, sizes, and durometers, to obtain accurate flow
rates. It can accept two stacked pumps with fluid flowing in the same direction
in both pumps, or one pump on each side with fluid flowing in opposite
direction in the pumps. The pump motor is equipped with user friendly
software and four modes of pumping: RPM, FLOW RATE, TIME, and TOTAL
VOLUME.

8.4 Maintenance

There is no need for any preventive maintenance work. There are no user
serviceable parts inside the peristaltic pump motor. All bearings are pre-sealed
and rated for long life. Do not open the unit, or the warranty will be voided.

The fuse may be replaced from the outside of the unit. Refer to figure 1.2 for the
location. Simply press down on the plastic fuse holder door, and slide it open.
The fuse used by the pump motor is closest to the case. The spare fuse is located
under the word “Press”. Make sure Power is off and the line cord unplugged
when changing the fuse.
