Introduction
This manual has been prepared as a guide for the persons who will be operating and maintaining your
tank cleaning machine. The key to long life for your tank cleaning machine will always be a system of
carefully planned maintenance; 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.
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 Customer Service Department and world-wide net of Distributors will be pleased to
help you. Please quote the type and serial number with all your enquiries; this will help us to help you.
The type and serial number are placed on the gear house of the tank cleaning machine.
Note: The illustrations and specifications contained in this manual were effective at the date of printing.
However, as continuous improvements are our policy, we reserve the right to alter or modify any unit
specification on any product without prior notice or any obligation.

Intended Use
It is to be verified by the end-user:
- that the tank cleaning machine is in conformity with respect to tank, vessel or container size in
which it will be used.
- that the construction materials (both metallic and non-metallic) are compatibility with product,
flushing media, cleaning media, temperatures and pressure under the intended use.

General Description
The Toftejorg MultiJet 65 is a media driven and media lubricated tank cleaning machine. As it is self
lubricating, there are no lubricating substances such as oil, grease etc. in the machine which need to
be regularly changed.
Functioning
The flow of the cleaning fluid into the 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 machine
body and a vertical rotation of the nozzles.
Machines with 2 nozzles
The combined motion of the machine body and the nozzles ensures a fully indexed tank cleaning
coverage. After 11¼ revolutions of the Hub with nozzles (10 3/4revolutions of the machine body), one
coarse cleaning pattern is laid out on the tank surface. During the following rounds, this pattern is
repeated 3 times, each of which is displaced ¼ of the mesh in the pattern. After a total of 45 revolutions
of the Hub with nozzles (43 revolutions of the machine body), a complete cleaning pattern has been
laid out, and the first pattern is repeated.

General Description (continued)
Machines with 4 nozzles
The combined motion of the machine body and the nozzles ensures a fully indexed tank cleaning
coverage. After 5 5/8 revolutions of the Hub with nozzles (5 3/8 revolutions of the machine body) one
coarse cleaning pattern is laid out on the tank surface. During the following rounds, this pattern is
repeated 7 times, each of which is displaced 1/8 of the mesh in the pattern. After a total of 45 revolutions
of Hub with nozzles (43 revolutions of the machine body), a complete cleaning pattern has been laid out,
and the first pattern is repeated.
First cycle Full pattern
General for both 2 and 4 nozzle machines
The speed of rotation of the turbine depends on the flow rate through the machine. The higher the flow
rate is, the higher the speed of rotation will be. In order to control the RPM of the machine for a wide
range of flow rates, the efficiency of the turbine can be changed (50% - 100% - 0% Turbine/Inlet
guide).
Apart from the jet flow through the nozzles, fluid is leaking through the top of the machine, at the hub
and through the bottom cover. The leakages between the moving parts at the top and at the hub are
cleaning the gabs and thus preventing build-up of material that might cause extra friction. The flow
through the bottom cover is due to the fact that the machine is media lubricated, and that accordingly a
flow through the gearbox is needed.
