1.3. Inspection
On receiving delivery of your IBC Mixer please inspect carefully to confirm that
your mixer has been received un-damaged and to the correct specification. Report any
shortages or damage immediately in writing to the carrier or supplier. Contact details
can be found at the back of this manual.
1.4. Storage
IBC Mixers series LBC, HBC should be stored in an indoor, clean, dry location
with a controlled temperature of 15°C to 40°C until the mixer is ready to be used.
1.5. Description
Tapflo IBC Mixers series LBC, HBC are designed for use on Industry standard
Intermediate Bulk Containers (IBC) with a 150mm screw cap and are suitable for most
container types.
The IBC mixers are for use indoors in a safe area only and is fitted with a DOL
starter with overload protection and a safety switch to prevent the mixer operating if the
mixer is not securely mounted on an IBC and a 16 AMP appliance Inlet plug protection
IP44 - splash proof.
The mixer drive is supported on a lightweight stainless steel bridge which
mounts directly onto the IBC and is held in place with quick action toggle clamps,
standard lifting is an eye bolt for lifting with a hoist or optional fork lift module.
1.6. Safety
The following instructions are important.
• Observe all site safety procedures installing and operating your IBC mixer
• Familiarize yourself with the material being mixed in the IBC and obtain product safety
data sheets, protective clothing and appropriate eye protection before proceeding.
• Use lifting equipment i.e. fork lift or hoist to install the mixer onto an IBC mixer. Mass
in Kg is indicated on the mixer nameplate.
• Mount the mixer securely onto the IBC complete with shaft and impeller before
connecting to the power supply.
• Disconnect from the power supply before moving the mixer or carrying out
maintenance.
• Do not touch any moving / rotating parts.
• Do not touch the motor after use - Hot Surface
WARNING – failure to observe safety instructions could cause severe personal injury.

2. Installation and Operation
2.1. Installation
The mixers with electric drive are supplied pre-wired and fitted with a DOL
starter, overload protection, safety interlock and appliance Inlet Plug.
The plug colour indicates the power supply required.
•Red - indicates a 400v 3ph 50 Hz supply
•Blue - indicates a 220-240v 1ph 50 Hz supply
•Yellow - indicates a 110v 1ph 50 Hz supply
The mixers with pneumatic drives are supplied with a flow control valve to regulate the
motor speed and an exhaust muffler.
1. Check that the motor / starter voltage requirements correspond with the supply
or verify if compressed air supply system is suitable in case of mixer with air
motor.
2. Check that the mixer shaft direction of rotation corresponds to the rotation
arrow placed on the mixer nameplate - rotation is clockwise when viewed from
above.
3. Changes to reverse the direction of rotation must be done by qualified personnel
only.
4. Fit the impeller on to the mixer shaft, dimple the shaft on assembly for the set
screws and tighten securely.
5. Fit the mixer shaft into the drive head coupling and tighten the 2 set screws
(Item 5) through the slot provided in the coupling guard.
6. Lower the mixer on to the IBC frame with a forklift truck or hoist using the eye
bolt provided on the mixer.

IOM Manual – IBC Mixers
Mixers - LBC/HBC 8
7. Securely fasten the mixer onto the IBC frame with the 2 quick action clamps
provided - adjust the clamps if necessary.
8. When the mixer is securely mounted on the IBC frame the power supply or
compressed air supply can be connected if safe to do so.
9. After use before moving the mixer - isolate from the power supply and
disconnect the lead to the appliance plug. In case of an air motor, it should be
disconnected from the compressed air supply.
10. Check that the securing clamps have been released before lifting / removing
the mixer from the IBC. The clamps are fitted with a locking plunger - pull the
button to release as illustrated.

Mixers - LBC/HBC 9
2.2. Operation
Tapflo Mixers series LBC, HBC can be driven by an electric motor with a DOL
starter or gearmotor with a frequency inverter. Mixer shaft speed can be change by
turning the potentiometer on the inverter - for more detailed instruction please refer to
the Leroy Somer instruction manual supplied with this mixer. Mixers can be also driven
by an air motor equipped with exhaust muffler and a flow control valve to regulate the
motor speed.
Always ensure access to the power supply or compressed air supply is kept clear.
Before operation visually check that all components are in a serviceable condition and
not damaged.
The mixer can be operated at any liquid level.

3. Maintenance
3.1. Routine Maintenance
Every 6 months
Check the security of all nuts and screws, and ensure all components are in a
serviceable condition and not damaged. Check that the mixer gearbox, electric motor
or air motor muffler are kept clean.
Visually inspect electrical components, cables, air lines for damage and rectify before
use. Electric motors do not require any internal maintenance and should be replaced if
a fault occurs.
Every 12 months
In-service inspection and testing of electrical equipment - Formally inspect and test
electrical components and cables in accordance with the portable appliance testing
(PAT) regulations in the UK, BGV A3 in Germany or local site codes of practice as
applicable.
3.2. Lubrication
Electric motor bearings are sealed for life, and do not require any maintenance or
re-lubrication.
The gearboxes are factory filled with Shell CASSIDA 220 food grade lubricant and
sealed for life.
Air line lubrication - use SAE #10 motor oil or equivalent for the air line lubrication.
3.3. Tightening Torques
Tighten all fasteners to values shown unless specifically instructed to do otherwise.
Lubricate all fasteners at assembly with grease, oil or an anti-seize material. Bolt threads
and contact surfaces of bolt heads and nuts should be lubricated.
The assembly on un-lubricated stainless steel fasteners cannot be recommended.
(1) If fasteners cannot be lubricated, multiply table values by 1.25.

3.4. Air Motor – Flushing
Flush the motor if it is operating slowly or inefficiently. Flushing the air motor removes
excessive dirt, foreign particles, moisture or oil that occurs in the operating
environment and will help to maintain proper vane performance/motor efficiency.
Safety - Flush the air motor in a well ventilated area. Keep face away from exhaust port.
Eye protection must be worn.
Use Gast # AH255B Flushing Solvent, or any non-toxic, non-flammable industrial
cleaning solvent. DO NOT use paraffin or ANY other combustible solvents to flush this
air motor.
3.5. Material Disposal
Tapflo IBC mixers series LBC, HBC are designed for a long trouble-free life. At the end of
the useful service life the lubricants and components can be recycled.
The IBC mixer, frame, shaft and impeller are manufactured from stainless steel and the
gearbox and electric motor from aluminium and cast iron.
Properly dispose of all mixer and gearbox parts responsibly, in particular lubricants
which must be collected for disposal or recycling in accordance with local authority
guidelines.
3.6. Ordering Spare Parts
To maintain your IBC mixer only Tapflo genuine spare parts are recommended. To
ensure safe reliable operation of your mixer please contact your local distributor for
spare parts.

4.2. Mixer Shaft – Direction of Rotation
The direction of rotation for the mixer shaft is clockwise when viewed from above, as
indicated on the mixer nameplate.
Changes to electrical connections to reverse the direction of rotation must be done by
qualified personnel only.
4.3. Air requirements
The air motor requires a clean dry lubricated shop compressed air supply. An Air Line
Filter / Regulator & Lubricator is required in the supply line.
Adjust the air line lubricator to 1 drop of oil per minute. Regulate the line pressure to 7-
bar max.
Noise-air motors are supplied with the standard muffler on the exhaust air.
4.4. Impeller Installation
Folding impellers are normally mounted on the end of the shaft as illustrated, and is
secured in place by two screws.
Dual Impellers - For viscous materials, Dual Impellers ensure a good top to bottom
turnover in the IBC with the second impeller positioned approximately halfway up the
shaft. Dual impellers can also be used for wetting powders with the upper impeller
positioned approximately 150mm below the liquid surface.

IOM Manual – IBC Mixers
Mixers - LBC/HBC 16
Low-Level Impeller (Kicker) - A low-level radial flow fixed impeller can also be
supplied for mixing the IBC contents at very low liquid levels - install below the folding
impeller as illustrated. A 1000mm long shaft is available with this option to position the
lower impeller close to the bottom of the IBC.
