1.0 SAFETY WARNINGS
Please read and observe all warnings contained in this operations manual before making
any attempt to operate the equipment.
Misuse of equipment
Use the equipment only for its intended purpose. Care should be taken to prevent over
pressurization of the pump or accessories connected to it. Use and repair only with proper
parts. Improper use or misuse of this equipment could result in fluid being splashed or
sprayed on the skin or in the eyes, serious bodily injury, property damage, fire or
explosion.
Make daily maintenance check on the equipment and repair damaged or worn parts
immediately. Do not alter this equipment in any way as doing so could cause drum mixer
malfunction and/or serious bodily injury.
Material & fluid compatibility
Always ensure the chemical compatibility of the fluids and solvents with the wetted parts
when using IPM equipment. Check the fluid manufacturer s data sheets and specifications
before using chemicals or solvents with IPM equipment.
Pressurized hoses
Because the air and fluid hoses are pressurized they present a potential danger should the
air or fluid escape at high pressure. This escaping fluid can spray out and cause serious
bodily injury or property damage. Inspect frequently and ensure that the hoses do not leak
or rupture due to wear, misuse or damage.
The drum mixer and hoses should be handled properly; do not use the drum mixer or
hoses as leverage to move the equipment. Use the hoses only for fluids in which they are
compatible with for both the inner liner and the outer covering. Use care not to exceed the
temperature rating of the hose.
Before each use, ensure that the fluid and air couplings are tight and not damaged. Check
the drum mixer and components for leaks, bulging hose cover, damaged fittings and loose
bolts. Always ensure drum mixer is secure in bung before operation.
Pressure specification
The maximum working air pressure of this equipment is 100 psi (7 bar). Ensure all
equipment and accessories used with this drum mixer are rated to withstand this maximum
working pressure. Never exceed the maximum working pressure of the mixer or any
device attached to it.

3.0 OPERATION
3.1 Drum mixer operating tips
An 8″ blade on the bottom of the mixer shaft is standard on each drum mixer to get
maximum pull of heavy materials from the bottom of the barrel. Additionally, two 6 upper
blades assist in pulling fluid from the sides of the drum for optimum mixing capability.
If you do not have a center bung in your drum, IPM has designed an off-set bung adaptor
riser (IPM part #500515) that angles the mixer shaft away from the sides of the drum to
allow proper chemical mixing. As a temporary measure, you can also take an 18″ 20
piece of 2″ diameter threaded pipe and screw into your bung. Carefully bend/point the top
of the pipe away from the center of the drum, tilting the bung for better mixer clearance.
The amount of air you will need to mix your fluids will depend on certain factors such as
viscosity, mixing speed, specific chemical, temperature, etc. Typically, 10 -20 CFM air
pressure is sufficient for mixing operations. A 1/4 ball valve can be used effectively as a
metering or speed control measure.
An automatic air line lubricator should be installed in the air line as close as possible and
no more than 18 inches (1/2 meter) from the air motor. Install the lubricator level with or
above the air motor so that the oil mist will blow directly into or fall down into the motor. Fill
the oil reservoir to the proper level with Gast #AD220 or SAE 10W high detergent or non-
detergent motor oil. Adjust lubricator to feed 1 drop of oil for every 50 – 75 CFM ((1.5 – 2
M3 per minute) air while the unit is running, or 1 drop of oil per continuous minute of run
time. Do Not overfeed oil or exhaust air may become contaminated.
Proper blade rotation is important for the swing out style blade assemblies to function
correctly. Looking from the bottom of the drum mixer, the shaft/blade rotation should be
clockwise for proper swing-out of the blades.
For the most efficient output and control of speed, use air lines that are the same size as
the motor inlet port if the connection is less than 7 feet (2 meters). For longer connections,
use the next pipe size larger than the motor intake port. Connect lines to motor in the
proper direction.
Do not add any thrust to the end or side of the shaft when making connections.
Check all connections before starting motor. It is your responsibility to operate this product
at recommended speeds, loads and room ambient temperatures. Do not run the motor at
high speeds with no load. This will result in excessive internal heat that may cause motor
damage.
Certain chemicals are the type that set up or seize the folding blades if allowed to solidify
on the blade assemblies. ENSURE YOU PERFORM THIS OPERATION IN AN AREA
THAT IS WELL VENTILATED AND HAS NO FIRE HAZARDS. If this should happen, an
effective way to remove the hardened chemicals is to heat the blades with a welding or
propane torch to burn the residue off. Since the blades are stainless steel, the heat will not
7
adversely affect them. It is not necessary to heat the blades to a point they become red
hot. Once the cleaned blade assemblies have cooled, clean the remaining debris from the
assembly and lubricate with WD-40 or an equivalent lubricant, then test to ensure they
swing freely for proper operation.
Use a pressure regulator and/or simple shut-off valve to regulate the motor s speed and
torque. This will provide the required power and will conserve air. Open the air supply
valve to the motor. Set the pressure or flow rate to the required speed or torque. Adjust the
lubricator to feed one drop of oil for every 50 – 75 CFM (1.5 – 2 M3 per minute) of air
moving through motor. Check the oil level daily.
A few drops of oil in the air inlet port helps to lubricate the air motor. With proper
maintenance, the air motor on this drum mixer will work efficiently for many years. If
moisture is present in your air supply, muffler freezing can occur during longer mixing
operations. If this happens, simply take the muffler apart and wash in warm water. Ensure
the muffler is completely dry before re-installing it back on the air motor. Do not drop the
air motor as the hex top cap is plastic.
Use Gast #AD220 or a detergent SAE #10 automotive engine oil for lubricating.
Lubricating is necessary to prevent rust on all moving parts. Excessive moisture in air line
may cause rust or ice to form in the muffler when air expands as it passes through the
motor. Install a moisture separator in the air line and an after cooler between compressor
and air receiver to help prevent moisture problems.
The DM-101 drum mixer is a very effective tool in 55 gallon barrel mixing operations.
Complete fluid mixing can be achieved in short periods of time, usually within 30 minutes.
The unique folding action design of the blade allows the mixing shaft to pass through the
2 bung in most drums and with two 6 and one 8 blade, optimum mixing is achieved
throughout the drum.
3.2 Fluid mixing tips
Do not pull too deep a vortex as this will entrap air into the fluid.
Do not pull too shallow a vortex as this will cause unbalanced mixing of fluids.
Tilting the barrel slightly will help reduce air entrapment.
For proper mixing, the actual blades should be 1/3 the diameter of the drum.
Example; a 24 drum requires an 8 mixing blade.
Mix fluids for only 30 45 minutes. Don’t over mix chemicals.
Slower speeds entrap less air into fluids during mixing process.
Never mix ISO fluid with drum mixer as this will entrap air into the chemical.
B components in fast set coatings such as polyurea require mixing with drum
mixer.
Always lubricate drum mixer motor for maximum life expectancy.
Collapsible blades make IPM drum mixer compatible with any barrel.
Use IPM’s new 13 mixing blade assembly for tote application.
Use off-set bung adaptor riser to prevent mixing blades from contacting interior
drum wall on drums with an off-center bung hole.
