SAFETY PRECAUTIONS

• High voltages exist and are accessible in the controller.
Contact Cole-Parmer for servicing.

• Do not operate mixers where explosive vapors or flammable
materials exist. Death or serious injury could result. Check
NEC and local codes before installing.

• Never clean the controller or mixer head while power is
applied to the system.

• Use only those mixer shafts that are properly sized for the
mixer head being used. Refer to mixer head specifications for
the proper shaft diameter or range to be used. Sizes other than
those specified can cause injury to personnel or damage to
equipment.

• Disconnect the AC power input line cord before connecting the
mixer head cable.

• Exercise extreme care when adjusting mixer height and/or
position to avoid personal injury. Never make these
adjustments while the mixer shaft is rotating.

• Never insert or remove the mixer shaft/impeller while the mixer
shaft is rotating.

• Be sure speed control is fully counterclockwise before the
POWER switch is placed in the FWD or REV positions. (50007­00 and 50007-05 Controller)

• Check that all cords are clear of any moving parts and not
subject to splashes or spills.

• Use care when setting the operating speed of the mixer.
Operation at high speeds in small mixing vessels could result
in hazardous splashing on the operator and equipment.

• When running at full speed and load at higher ambient
temperatures, the mixer head may get very hot to the touch.

• Use of mixing shafts and impellers larger than those
recommended could result in poor product performance and
shortened service life.

• Mixer shafts must be inserted into high-speed through-shaft
mixers at least 3 inches (8 mm) and the collet hand-tightened
firmly to ensure adequate shaft retention. Keep mixer shafts as
short as possible to reduce resonant vibrations caused by the
shaft flexing at higher speeds.

• The mixer head is to be used only for mixing. It is not intended

for any other purpose.

INTRODUCTION

The Stir-Pak 50007-series heavy-duty modular mixing system covered in this manual consists of eight different

mixer heads and two analog controllers for 115VAC and 230VAC operation.

The ServoDyne 50008-series digital modular mixing system consists of four different mixer heads and a

precision digital controller for 115VAC operation.

The following chart cross-references the model number, operating speed range and torque rating of the mixer
heads and the compatible controller.

50007-00, -05 STIR-PAK CONTROLLER

The variable-speed controller, Figure 1a and 1b, is used to set the speed of the mixer heads and provides
a 100:1 adjustment range.

The controller ensures accurate, dependable motor speed (mixing) control, with “soft-start” and smooth, gradual
adjustment to the speed setting. Constant speed with a 100:1 adjustment range is maintained electronically via
automatic compensation for changes in load torque demands at both high and low speeds. Built-in motor current
compensation minimizes speed drift with changes in load. Motor current limiting protects the system in case of a
locked rotor condition. Output circuit protection protects against inadvertent output shorting. Mixer rotation is
reversible.

INSTALLATION AND SETUP PROCEDURES

The mixer heads are equipped with an adjustable-tilt mounting assembly. The mounting assembly is designed
to be attached to an optional mixer support stand or tank clamp. Components supplied as part of the mixer
package include the following:

• Mixer head with 6-ft cable

• Precision controller with 6-ft line cord

• 3-jawed chuck on high-torque mixers

• ⅜-inch collet on high-speed mixers

• Adjustable-tilt mounting assembly with support rod

Installation of Adjustable-Tilt Mounting

• Never insert or remove the mixer shaft/impeller while the mixer
shaft is rotating.

Perform the following steps:

1. Attach mixer head to adjustable-tilt mounting assembly as follows:

a. For Stir-Pak models 50007-10, -15, -20, -25 and ServoDyne models 50008-10, -20, attach mounting

assembly with four screws and lock washers. (See Figure 3a)

Figure 3a: 50007-10, -15, -20, -25 and 50008-10, -20 mixer head mounting

b. For Sir-Pak models 50007-30, -35, -40, -45 and ServoDyne models 50008-30, -40, attach mounting

assembly with two screws and lock washers. (See Figure 3b)

Figure 3b: 50007-30, -35, -40, -45 and 50008-30, -40 mixer head mounting

Note: The mixer is now ready to be attached to a support stand or to a tank clamp (not supplied).

Recommended stands, tank clamps, and a double (rod) clamp are available through Cole­Parmer. Part numbers are listed in the ACCESSORIES section.

Installation Using a Support Stand

1. Set up support stand in accordance with the manufacturer’s instructions.

2. Attach a double (rod) clamp to the vertical rod on the support stand and tighten clamp screw. (See
Figure 4)

3. Slide rod of adjustable-tilt mounting assembly into clamp and secure with clamp screw.

4. Select an impeller and shaft for the required operation and install as follows:

a. Place impeller on shaft and tighten set screw.

b. For high-torque mixers head, slide the shaft of the stirring device into the three-

jawed chuck and tighten chuck.

c. For high-speed mixer head, slide the shaft through the collet at least 3 inches and hand-tighten

collet.

5. Place support stand legs around vessel. Tilt angle is adjustable from 0 to 30 degrees.

6. Position the height of the mixer head by moving the clamp up or down on the support stand or, on high­speed models, by loosening the collet and positioning the shaft.

• Exercise extreme care when adjusting mixer head height and/or
position to avoid personal injury. Never make these
adjustments while the mixer shaft is rotating.

• Mixer shafts must be inserted into high-speed through-shaft
mixers at least 3 inches and the collet hand-tightened firmly to
ensure adequate shaft retention. Keep mixer shafts as short as
possible to reduce resonant vibrations caused by shaft flexing
at higher speeds.
