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:
Loctite Product Numbers:
51168: Food Grade Anti-Seize; 8 oz. brush top
51170: Food Grade Anti-Seize; 2 lb. can
51171: Food Grade Anti-Seize; 40 lb. pail

Performance Curves – PRESSURE & FLOW

Related as number of nozzles x orifice and guide vane/turbine configuration.
For Example: 4x7 (21) is: 4 nozzles at 7mm each with a type 2 guide vane and type 1 impeller
Note: Throw lengths are measured as horizontal throw length at static condition. Vertical throw length upwards is approximately 1/3rd less. Effective throw length varies depending
on jet peripheral speeds over the surface, substance to be removed, cleaning procedure and cleaning agent. The inlet pressure has been taken immediately before the machine
inlet. To achieve the performance indicated in the curves, allowance must be made for pressure drop in the supply lines between pump and machine.

Maximum jet-length on this curve is measured at static conditions and where the last droplet falls. The effective range is subjective to the cleaning requirement. However in this
curve effective is at the point of arc deviation.
