INTRODUCTION
The instructions in this manual are task oriented to allow easy access
to the desired information. Figure 1 provides summarized information
on all controls to the Pump Drives. This manual contains complete
information on installing and setting up the Pump Drives, as well as
operating and servicing at the user level. The following chart provides
basic information on models covered in this manual.
Drive
Catalog Output Flow Power
Number rpm rate Requirement*
900-1103 50 to 5000 2.5 - 5450 mL/min 90 to 130 VAC
900-1104 190 to 260 VAC
900-1105 90 to 9000 0 - 7.0 gpm 90 to 130 VAC
900-1106 200 to 260 VAC
*AC voltages can be either 50-60 Hz.
The Pump Drives contain the pump drive motor and motor controls in
one compact unit. MICROPUMP pump heads are attached directly to
the motor which is accessible from the front panel. In addition, these
drives incorporate the following features:
• Permanently lubricated motor for continuous duty
• Motors are soft-starting
• Speed control over a 100:1 range
• Pumps are magnetically coupled to motor
• Stackable
• IP22 rating per IEC 529
• Replaceable Motor Brushes
(purchase pump head separately)
(with provided pump head)
900-1105 and 900-1106 are supplied with a centrifugal pump attached.

DESCRIPTION
These electronic drives are self-contained compact units which include
a drive motor and all operating controls (see Figure 1). These drives
are especially designed for magnetically coupled pumps.
The 900-1103 and 900-1104 drives come without a pump head. It will
accept all MICROPUMP pump heads with standard mounting canisters. The pump heads can be easily mounted to the motor that is
accessible from the front panel. High and low speed versions are available covering a wide range of flo w rates.
able pump heads and performance information.
Note: Gear pumps should not be operated above 5000 rpm.
The 900-1105 and 900-1106 drives come with a 7-GPM Centrifugal
Pump head mounted on it. The pump head has 3/8 in NPT(F) inlet and
1/4 in NPT(F) outlet ports.
The solid-state speed control circuitry offers excellent speed regulation even with line v oltage and load v ariations. A PO WER indicator on
the front panel illuminates whenever the ON/OFF switch is in the ON
position. Pump drive speed can be manually controlled over a 100:1
range with the front panel mounted potentiometer. “Soft-start” and
smooth gradual acceleration to speed setting is provided when line
power switching.

INSTALLATION/SETUP
Unpack the Pump Drive and retain all packing material until proper
product operation has been verified.
The Pump Drive rests on four vibration isolator f eet f or placement on a
bench, desk, or table. It is supplied with a power cord attached.
1. If applicable, attach the MICROPUMP pump head.
2. Check that the ON/OFF Switch is in the down (OFF) position.
3. Connect the A C power cord on the rear panel to the A C power source.
4. Set the speed control to zero.
5. Install the pump belo w the lev el of the supply liquid. The liquid must
be under atmospheric conditions.
6. This completes the basic setup.
Note: To prevent damage to pump; do not restrict pump inlet or run the
pump dry .
OPERATION
Operation of the Pump Drive has been simplified requiring only two
controls, the ON/OFF Control and the Speed Control (see Figure 1).
The operation of each of these controls is explained below. When operating the drive, allow approximately 20 minutes for warm-up speed
drift to become minimal.
ON/OFF Control
The ON/OFF Control is used for turning power ON or OFF. When the
control is in the down position, power is OFF and the green POWER
light is not lit.
Speed Control
The Speed Control setting determines the rpm of the pump and therefore, the flow r ate . Depending on the model the maximum speeds will
be either 5000 or 9000. Rotating the Speed Control clockwise increases
speed linearly .

Troubleshooting
SYMPTOM CAUSE REMEDY
The motor does not
rotate, when the ON/
OFF switch (Figure 1) is
moved up. P ower
indicator does not glow.
Erratic variations
in speed.
No power.
Worn motor brushes.
1. Chec k that Pump Drive
is plugged into a power
source.
2. Return for servicing.
See “Motor Brush
Replacement Procedure. ”
Cleaning
Keep the Pump Drive enclosure clean by wiping down with a mild
detergent. Never immerse or use excess fluid.

Motor Brush Check/Replacement
Note: Brushes should be checked every 6 months, or approximately
500 operating hours or if erratic operation occurs.
DANGER: High voltages exist and are accessible in
the Console Drive. Use extreme caution
when servicing internal components.
1. Place the Power switch in the off position.
2. Disconnect the AC power input line cord from the AC receptacle.
3. Remove the four screws from each side of the housing and lift off
the housing.
4. Carefully unscrew each brush cap on opposite sides of the motor
(Figure 2). Withdraw the brush, and examine it for wear.
Figure 2. Typical Brush Replacement
Note: Replace both brushes, if either brush is less than 0.300 in
(7.6 mm) long from base to point.
5. Insert brushes and install brush cap on each side of motor.
6. Install housing and secure with the four screws on each side.
7. Connect the AC power input line cord to the AC receptacle.
