INTRODUCTION
General Description
The OMEGA®peristaltic pump is self-priming and can handle a wide
variety of viscosities (from air to heavy slurries) with positive
displacement.
The OMEGA®peristaltic pump can be used to pump fluids or gases
without contamination of the pump - the material contacts only the
tubing. The positive displacement feature makes this pump ideal for
metering applications. Each revolution of the roller assembly delivers a
precise amount of fluid.
The easy changeability of the OMEGA®peristaltic pump tubing makes
this the ideal pump for diverse quick change repetitive pumping jobs.
Flexible, reliable and cost efficient, the OMEGA®peristaltic pump can
fill most all of your fluid movement requirements.

OPERATIONAL INFORMATION
Installation Instructions
Power Requirements: Voltage and frequency of power supply must be
the same as shown on unit.
Wiring Connections: All wiring and electrical connections must comply
with national electrical codes and local electrical codes.
Mounting:
a) Mount OEM model mounting bracket to any flat, rigid surface, using
four #10-32 screws.
b) Case enclosed model may be placed on any flat surface, assuring
space is provided at the back of the case for air circulation through
ventilation holes.
Mounting Location: Pump should be used in a dry location with an
adequate supply of cooling air. The ambient temperature should not
exceed 25°C.
This unit should not be used outdoors or in hazardous
locations.
Instructions for Optional Timer
1. Rotate the program disc in the direction of the arrows to align the
correct time of day with the time mark.
2. Set the desired switching program by pushing the switch actuators
toward the center of the time switch. Each actuator provides a 15
minute “ON” time. The now visible orange area(s) indicate the
switch “ON” period

ROLLER & TUBING SELECTION
Use the following color coded rollers with the appropriate tubing ID:
Roller Color Tubing ID mL Per Revolution
Black 1⁄4"3.5
Black 3⁄16"2.1
Red 1⁄8"0.84
Red 1⁄6"0.21
Instructions for 1/16" Tubing Assembly
Insert 1⁄16" tubing into the sleeve and pull out desired length of 1⁄16"
tubing. Secure 1⁄16" tubing by placing the tie fastener approximately 1⁄4"
from one end of the sleeve and tighten fastener so that 1⁄16" tubing is not
easily moved. Be careful not to collapse the inner tubing by over-
tightening the tie fastener. Install the tubing with the tie fastener on the
inlet side of the pump.
Make sure the tie fastener is on the outside of the pump
housing and is not interfering with the roller assembly.

ASSEMBLY INSTRUCTIONS
1. Assemble mounting plate (4) and pump housing (5) to gearmotor (3)
with with three #10-32 x 11⁄4" long screws and one #8-32 x 7⁄8" long
screw (2).
2. Slide white plastic washer (8) onto motor shaft. Press roller bracket
assembly (9) onto the motor shaft with the four self-locking teeth
toward the gearmotor. (As shown in the view above.)
3. Insert tubing (6) into pump. housing (5) inlet and work tube into
roller race as you rotate the roller bracket assembly. See details on
page 5.
4. Assemble pump cover (10) to pump housing. (5) with four #8-32 x 5⁄8"
long screws (11).

TUBE INSPECTION AND REPLACEMENT
Tubing Inspection:
Inspect all tubing regularly and replace it if deterioration occurs. Use
the following instructions to replace pump tubing.
Tubing Replacement
1. Disconnect the power to the pump.
2. Disconnect the suction and discharge tubing from the tubing.
3. Remove four screws and pump cover.
4. Remove old pump tubing and discard.
5. Clean roller race, removing any particles that could damage tubing.
6. Position the roller bracket assembly as shown in Fig. 1.
7. Push the new tubing into the inlet port anchoring the tubing in
grippers (see Fig. 2) while rotating the roller bracket assembly.
8. Continue to rotate the roller bracket assembly, pushing the tubing
into the roller race.
9. Finally, insert the tubing into the outer port (Fig. 4), and replace the
cover and screws.

OMEGA®VARIABLE SPEED DRIVES
FPU250 SERIES
7
OMEGA®VARIABLE SPEED DRIVES
SERIES FPU 250
OMEGA®variable speed drives are powered by a DC gearmotor. A
specially designed electronic speed control system provides smooth
acceleration control over the entire flow range. The three position
on/off switch allows the user to maintain speed setting when unit is
turned off or reversed. This unit is designed for continuous operation at
any speed. All variable speed drives are rated for continuous duty at
25°C ambient.
Fuse: Replace with type AGC-1/2 Amp. Use AGC-1 Amp for dual head
pump.
Alternate Tubing Replacement Method for Medium and High
Variable Speed Units
With unit running at high RPM, pull old tubing out from outlet port of
pump. Install new tube by inserting into inlet port; continue feeding
tube 1⁄4" in at a time, allowing the roller assembly to push tubing until
tube extends out from outlet port. Pull tubing from outlet port until
desired tubing extension is obtained. Run unit for about one minute to
allow tube to seat properly.
Depending on pump model, tubing in use and fluid being
pumped, roller assembly may stop rotating when
speed/flow control is set at the low end range. Avoid
prolonged operation in the stalled position for longer motor
life.
