INTRODUCTION
This manual has been prepared as a guide for the persons who will be operating and maintaining your Butterworth® tank cleaning
machine. The key to long life for your tank cleaning machine will always be a system of carefully planned maintenance. Tank cleaning
machines are expected to perform various types of cleaning jobs. Some applications will require that maintenance is performed more
often than with less stringent applications. A properly designed and maintained CIP (Clean In Place) System is paramount to the service
life of any tank cleaning machine.
It is in your own interest to get the best and most economical performance from your tank cleaning machine. Neglect of
maintenance means poor performance, unscheduled stoppages, shorter life and expense. Good maintenance means good
performance; no unscheduled stoppages and better total economy.
You will find the information contained in this manual simple to follow, but should you require further assistance, our Technical Department
and worldwide net of Distributors will be pleased to help you. Please quote the type, model, and serial number with all your inquiries; this
will help us to help you. The type and serial number are placed on the main body, just below the nozzle body

GENERAL DESCRIPTION
The Butterworth® LT is a sealed gearbox tank cleaning machine that uses lubricant (see page 35 for lubricant specifications).
How It Works
The flow of the cleaning fluid into the tank cleaning machine passes through a turbine, which is set into rotation. The turbine rotation is
through a gearbox transformed into a combined horizontal rotation of the body and a vertical rotation of the nozzles.
The combined motion of the machine body and the nozzle body creates a pattern matrix on the tank walls similar to the images below,
keeping in mind that this pattern will propagate differently in geometries other than those shown here. In other words, the pattern would
look different in a vertical cylindrical tank when compared to a horizontal cylindrical tank for a given location of the machine. The LT
requires 65 axial revolutions to complete one pattern before it begins to rotate over the same location for a given coordinate within the
tank. The images below show a progressive build up of the pattern matrix for a horizontal cylindrical tank. The far left image shows a
course build up of the matrix, with the middle image showing a more progressive view and the far right image showing a complete pattern.
The far right image is representative of the maximum density for this geometry.
Figure 2
The speed of rotation of the turbine depends on the flow rate through the machine and the type of stator/turbine employed within the tank
cleaning machine. The higher the flow rate is, the higher the speed of rotation will be; subject to the style of the guide vane (stator) and
impeller (turbine) within the machine. In order to control the RPM of the machine for a wide range of flow rates, the proper machine
configuration should be reviewed, relative to the cleaning application.
Apart from the jet flow through the nozzles, no other fluid by design is expelled from any other location on the machine. As this is a sealed
unit; start-up rotations are higher than for media-lubricated units.

This machine is equipped with a clutched hub. Care should be taken when installing and removing the machine to insure that the
nozzles are not inadvertently hit or knocked with any hard blows, as this would transmit forces on the gearing that is best avoided
to insure long life and reduced wear.
(Note: Optional configurations are available as non-standard products by contacting your nearest agent or distributor.)

INSTALLATION INSTRUCTIONS
Never attach the LT by grabbing the nozzles to
Tighten the machine onto the connection (Figure 3). The
Proper way to attach the LT can be seen in Figure 4.
The nature of stainless steel against itself can cause galling. When threading the inlet connection onto your fluid connection, it is
recommended that you employ either Teflon tape or another appropriated anti-seizing compound to avoid this event. See comments on
conductivity; page 11.
The following product is recommended:

INSTALLATION AND NORMAL OPERATION
General Installation Instructions
The Butterworth® tank cleaning machine should be installed in vertical position (upright or inverted). It is recommended to install a filter in
the supply line in order to avoid large particles lodging inside the machine. Before connecting the machine into the system, all supply lines
and valves should be flushed to remove foreign matter.
Recommended filtration: 100-200 micron
The Butterworth®tank cleaning machine as delivered has been tested at the factory before shipping.
Normal Operation
Cleaning Media: Use only media compatible with the materials as listed on the reference list of parts as indicated for your model; see
page 27.
After Use Cleaning: Depending on the type of cleaning that is being performed and the type of cleaning solution used, a procedure for
after use flushing of the cleaning system should be developed for your application. In general, a fresh water flush is recommended after
each cleaning.
Pressure: Avoid Hydraulic shocks. Increase pressure gradually; ramping up the pressure over 5-7 seconds. Do not exceed 300 PSI (21
Bar) inlet pressure. High pressure in combination with high flow rate will increase consumption of wear parts and should be expected
when compared to operations at lower pressures and flow rates.
Warning: If the machine is used in potential explosive atmospheres, tapes or joint sealing
compounds, which are electrical insulators, must not be used on threads or joints. In addition,
connecting pipe work must be electrically conductive and grounded to the tank structure. This
is essential to avoid the build-up of static electricity on the machine.

MAINTENANCE AND REPAIR
PREVENTIVE MAINTENANCE
In order to keep your Butterworth® tank cleaning machine servicing you as an efficient tool in your tank cleaning operations, it is essential
to maintain its high performance by following a simple preventive maintenance program, which will always keep your tank cleaning
machine in good condition.
The following recommended preventive maintenance program is based on tank cleaning machines working in average conditions.
However, you will appreciate that a tank cleaning machine, which has a rough and dirty job to do, will need more frequent attention than
one working in ideal conditions. We trust that you will adjust your maintenance program to suit.
Always use only proper tools. Use Butterworth® standard tool kit (page 24). Never force, hammer or pry components together or apart.
Always perform all assembly/disassembly steps in the order described in this manual. Never assemble components without previous
cleaning. This is especially important at all mating surfaces. Work in a clear well lit work area.
Every 400 working hours
1. Disassemble machine as described on the following pages leaving the gearbox intact; (position 37).
2. Thoroughly flush the machine prior to disassembly and insure that no hazardous material remains in the machine.
3. Upon complete disassembly of the machine; (except for position 37), all parts should be thoroughly washed and/or degreased in
the appropriate manner, then inspected accordingly.
4. Inspect seals and bushings for wear; locate position numbers from the exploded view drawing on page 32 and bill of materials on
page 27. Replace if unduly worn.
5. Inspect bevel gears located at position numbers 12.6 and 17. Replace if unduly worn.
6. Inspect gearbox rotation by inserting position 36 into position 32.3 then gearbox; position 37 observing gear timing into position
32.3. then rotate clockwise. If rotation is not consistent and smooth, then inspection of gears should be undertaken and replaced
where necessary. For representation of gear timing, see Figure 20.
7. A service card is included with this manual; (see page Error! Bookmark not defined.). This should be completed each time
service is performed on your tank cleaning machine so that a proper record/history is maintained.
Good maintenance is careful and regular attention!
