Introduction

1.1 Description

The peristaltic pump offers exceptional simplicity, ease-of­use, and variable flow capacity. The pump is self-priming
and non-siphoning. It prevents back flow since one of the
three rollers is always compressing the tubing. As one section
of a tube fatigues, simply move the tube along to an unused
section and continue pumping. To facilitate changing the
tubing, a latch mechanism allows for easy opening and
closing of the pump.

No tools are required to load the tube. Pumps are mounted to
a pump motor via two screws and can be double stacked.
Tubing can even be changed on stacked pumps without
detaching either of the pumps from the motor. Once tubing is
loaded, a clamp plate holds it securely in place during pump
operation. A single pump can handle a broad range of flow
rates and tube materials.

1.2 Features

⻬ Stainless steel rotor assembly

⻬ Ideal for use in sterile, corrosive, or general laboratory

operating environments.

⻬ Flow rates from 0.5 to 2280 mL/minute (36 gallons/hour)

⻬ Quick mounting to pump motor

⻬ Easily stackable mounting for multi-channel pumping

⻬ Three-roller geometry reduces pulsation and improves

priming

⻬ Polysulfone housing for durability and chemical

resistance

3.1 Introduction

To attach a single pump directly to a pump motor, follow the
procedure in Section 3.3.1.

To stack two pumps to a motor, follow the procedure in
Section 3.3.2.

To attach the pump to an adapter plate (for your own motor),
follow the procedure in Section 3.3.3.

To use your own adapter plate, follow the procedure in
Section 3.3.4.

Before you mount the pump to any pump motor, make
sure that power to the motor is turned off.

1. Refer to Figure 3-1. Make sure the pump is in the closed position.

2. Refer to Figure 3-2 and Figure A. Place the blade of a flathead
screwdriver in the groove of the Rotor Shaft (5). Rotate the Rotor
Shaft until its back tab slips into the groove of the motor shaft. Do
not try to force the pump onto the motor until you perform Step
#3.

3. Refer to Figure 3-3 and Figure A. Swivel the pump back and forth
slightly to align the holes on the back of the base (8) with the
alignment pins on the face of the motor. Press the pump base up
against the face of the motor.

4. Refer to Figure 3-4. With the pump and motor aligned, insert the
mounting screws through the mounting holes in the pump, until
they make contact with the threaded mounting holes in the face of
the motor.

5. Tighten the screws fully with a

9

⁄64 (M3.5) allen wrench.
