GENERAL INFORMATION
Variable flow Mini-Pump is a bidirectional, self-priming peristaltic pump for
precise low-flow deliveries. The squeezing action of the rollers on the tubing
progressively moves fluid through the tubing in advance of the rollers, resulting in
a peristaltic pumping action. The flow is proportionate to the speed of the pump
head and the inside diameter of the tubing, both of which can be varied. A
variable speed flow control and five different sized tubing assemblies provide fine
resolution with a wide range of flow rates. A PRIME (PURGE) setting is provided
to facilitate high speed emptying/filling operations. Mini-Pump is powered by a
12-volt wall adapter that plugs into a wall receptacle. A battery power cord is
also supplied for portable operation of the pump using a 9- or 12-volt battery.
SETUP
There are two power cords available; this enables Mini-Pump to operate from a
standard (120-volt, 60-hertz wall receptacle or European accessory adaptor
220-volt, 50-hertz) and from a 9- or 12-volt battery. Connect one end of the
appropriate power cord to the Mini-Pump and the other end to a power source,
the Mini-Pump is now ready to use.
AC Power Cord: This 6-foot cord has a single male plug on one end and a
wall adapter on the other. Insert the single male plug into the power receptacle
at the back of the pump housing and the wall adapter into a wall receptacle.
Battery Power Cord: This 7-inch cord has a single male plug on one end
and a 9-volt battery connector on the other. Insert the single male plug into the
power receptacle at the back of the pump housing and connect the battery
connector to a 9-volt battery.
NOTE: Mini-Pump can also be operated from a 12-volt car/storage battery by
properly splicing the wires to the 9-volt connector. Results are comparable to
those on ac operation. Operation of the pump on a 9-volt battery produces
slower speeds and flow rates. A standard 9-volt battery runs the pump for a
relatively short time (30 min or less) before becoming exhausted.
OPERATION
1. Release the protective transparent cover by depressing the tab on the plastic
retaining clip located at the bottom of the cover. The hinged cover can then
be raised to gain access to the pump head and tubing assembly.
2. Take the tubing assembly (plastic fittings and attached tubing) and wrap the
tubing around the pump head (white roller). Slide each plastic slotted fitting
into each metal slotted U-shaped retaining bracket.
3. Attach tubing to the IN and OUT barbed fittings on the pump.
4. Move Power/Direction switch (S1) to FORWARD, to activate pump head.
5. Move the Pump Speed switch (S2) to PRIME (PURGE), to quickly fill the
tubing with liquid.
6. Move the Pump Speed switch (S2) to SLOW or FAST.
7. Within each of the two speed ranges (SLOW and FAST), the flow rate can be
varied for precise delivery by rotating the Variable Flow Control knob (C1).
The adaptor tip is positive (+). Polarity reversal will damage
this product.
Selecting a higher reference number increases the revolutions per minute and the flow
rate of the pump.
8. Select a tubing size with a mid-range for the expected flow rate.
9. To extend tubing life, select a tubing size with the largest diameter pos-sible for the
desired output and operate pump at lower speeds (without stalling the pump). If too
large a diameter tubing is selected, and the pump is set at too slow a speed, the pump
motor may stall or stop.
10. The tubing in the tubing assembly will eventually wear out and must be replaced. To
replace tubing read the following sections: “Tubing Assemblies,” “Tubing,” etc.
NOTE: If very accurate flow control is important, allow the pump to operate for approximately 20
minutes to condition the tubing.
CAUTION: Mini-Pump is engineered to provide years of satisfactory service if handled
properly. Here are a few precautions:
• Do NOT run the pump in reverse for long periods of time. This will shorten the life of the
motor.
• Do NOT manually turn the pump head. Turning the pump head manually will damage the
pump gears.
• Do NOT touch the pump head while it is turning.
• This product is not designed for nor intended for use in patient-related applications.

(Instructions continued from page 1)
Slightly shorter tubing reduces the diameter by stretching the tubing and reducing
the flow. The flow rate can be reduced slightly by cutting the tubing slightly shorter
than indicated by the chart.
NOTE: The lengths given are for silicone tubing only, other tubing may require
slightly shorter or longer lengths. The flow rates listed are for silicone tubing supplied
with Mini-Pump.
For best results—
• Select a tubing size with a mid-range for the expected flow rate.
• To extend tubing life, select a tubing size with the largest diameter possible for
the desired output and operate the pump at lower speeds (without stalling the
pump). If too large a diameter tubing is selected, and pump is set at too slow a
speed, the pump motor may stall or stop.
TUBING ASSEMBLY REMOVAL
1. Release the protective, transparent cover by depressing the tab on the plastic
retaining clip located at bottom of the cover. The hinged cover can then be raised
to gain access to pump head and tubing assembly.
2. The tubing assembly is held in place by a slotted tube-lock at each end which is
fastened securely by friction fit in a metal U-shaped retaining bracket.
3. Grasp the tube-lock (white round slotted part) on each side of the retaining
bracket, and remove it by lifting upward.
4. Remove the other tube-lock in the same manner.
PREPARATION FOR INSTALLATION (TUBING ONLY)
1. After removing the tubing assembly, slide the slotted tube-lock on each end away
from the barbed fittings. Remove the barbed fittings and tube-locks from the
tubing, discarding the tubing.
2. Prepare a new length of tubing for installation by sliding a tube-lock over the end
of the tubing. Insert a fitting on the end of the tubing. Make certain to slide the
tubing over the barbed portion of the fitting. Repeat this procedure for the other
end of the tubing. The tubing assembly is now ready for installation.
TUBING ASSEMBLY INSTALLATION
The 1/4-inch (6.4mm) tubing assemblies have tube-locks that consist of nylon
washers—they are not slotted. All other tubing assemblies have tube-locks that are
slotted.

TUBING
This specially formulated pump tubing is made from FDA-approved ingredients. The
unique manufacturing process achieves a tubing flexibility greater than other tubing.
It is ultratranslucent so that the flow of the liquid can be observed. It is nontoxic,
odorless, and tasteless. It may be used to transfer ultrapure deionized/distilled water
with zero contamination. It is biocompatible, resilient, stretchable, and resistant to
compression set. Its high “weatherability” properties resist ultraviolet light, ozone,
and gases. May be used in the lab and outdoors. It may be autoclaved. Designed for
pumping very hot and very cold liquids, -80 to 500°F (-62 to 260°C).
