Table of Contents The information herein is correct at the time of issue but may be subject to change without prior notice. 1. Safety ....................1.1.
1 Safety Unsafe practices and other important information are emphasized in this manual. Warnings are emphasized by means of special signs. Always read the manual before using the tank cleaning machine! 1.1 Important Information WARNING Indicates that special procedures must be followed to avoid serious personal injury. CAUTION Indicates that special procedures must be followed to avoid damage to the tank cleaning machine.
Always handle lye and acid with great care. When an Alfa Laval Gamajet is operating, there should be covers over every tank opening. These covers should be sealed well enough to withstand the full force of the jet striking the cover plate.
Warning: In some conditions, the Alfa Laval GJ PF-FT may be allowed to be immersed while left in the tank. It is strongly recommended that you have prior approval from Alfa Laval Gamajet Equipment to ensure this will not harm the machine in any way.

Alfa Laval GJ PF-FT will function at any orientation. The Alfa Laval GJ PF-FT can be suspended from the top of the tank via a flexible hose. The dual nozzle machine is designed to have balanced forces in order to keep it centered even while hanging. We do not, however, recommend attaching the machine to a flexible hose while in the inverted or horizontal orientation.

The Alfa Laval GJ PF-FT can be used with either a centrifugal or positive displacement (constant volume), PD, style pump. In most cases, if the Alfa Laval GJ PF-FT is to be used with a centrifugal pump, the Alfa Laval GJ PF-FT should be configured so that the pump will operate close to its best efficiency point.
At end of use, the equipment must be recycled according to relevant, local regulations. Beside the equipment itself, any hazardous residues from the process liquid must be considered and dealt with in a proper manner. When in doubt, or in the absence of local regulations, please contact your local Alfa Laval sales company.
Initial Startup Every Alfa Laval GJ PF-FT that ships is accompanied by a Birth Certificate. This document indicates how the machine performed in our testing tank before it shipped based on the operating conditions supplied to Alfa Laval Gamajet. To ensure the longest possible life of the machine, please verify the operating conditions and, most importantly, the machine’s cycle...
4 Operation Pay attention to possible faults Read the instructions carefully 4.2 Trouble Shooting Cracked/ Loose Input Pinion (pos. 38) – Section 5.4 Inspection and Service of Components Does Rotor Bent Input Shaft (pos. 39) – Section 5.4 Inspection and Service of Components (pos.
Insufficient Flow The Alfa Laval GJ PF-FT was configured to meet certain operating conditions outlined at the time of the initial sale, such as flow rate (m^3/hr)(GPM), pressure (bar)(PSI), temperature, chemical content of the wash fluid, cycle time, etc. If the Nozzle (47) size is too small and/or the opening at the bottom of the Stator (12) is too large, the Tee Housing (8) will not turn.
Inadequate Drainage Ensure that the vessel drains the effluent (used wash fluid) as fast as it’s being sprayed in through the Alfa Laval Gamajet. The floor of the vessel should be sloped or pitched toward the drain and the drainage opening should be large enough to gravity- drain the effluent from the vessel.
4 Operation The Tank Cleaning machine is designed for cleaning in place (CIP). CIP = Cleaning In Place. Study the instructions carefully and pay special attention to the warnings! NaOH = Caustic Soda. HNO3 = Nitric acid. 4.5 Recommended Cleaning Step 1 Caustic danger! Always handle lye and acid with great care.
Always read the technical data thoroughly. (see chapter 6 Technical Data) Step 2 Recommended spare parts: Order service kits from the service kits list (See 7.10 Minor Service Kit & 7.11 Major Service Kit) Ordering spare parts: Contact your local Alfa Laval Sales company.
The Alfa Laval Gamajet should be washed out with clean water after each use to remove any foreign material or soft substances left in the machine that may harden during storage and cause the Alfa Laval Gamajet to seize or lock up. A clean water rinse through the Alfa Laval Gamajet will also wash out any residues of chemical cleaners or recirculated wash water that could adversely affect the O-rings during prolonged contact in storage.
5 Maintenance Read the instructions carefully. The items refer to the parts list and service kits section. 5.3 General Dismantling Step 1 Sanitary Inlet Loosen the Set Screw (34) with a 3/32” Hex Key, minimum 2 turns. Remove the Sanitary Inlet (11) and Stator (12). Warning: Hold or turn on Stem (7).
Examine the gears of the four different stages for any worn or broken teeth. Also, examine the Planetary Ring Gear (18) for bent or sharp teeth. If any damage is found, contact Alfa Laval Tank Equipment immediately. The gears in each level are interchangeable; they all have the same number of teeth.

(24) out of the (8). The press tools are available from Alfa Laval Tank Equipment. Before installing a new (24), clean the housing bores and remove any burrs resulting from a (24) removal.
All parts must be cleaned thoroughly before reassembling. Any deposits remaining on the parts can cause difficult disassembly the next time the Alfa Laval Gamajet needs servicing. Also, it may cause misalignment of parts and the potential for premature failure.

TRAX Simulation Tool TRAX is a unique software that simulates how the Alfa Laval GJ PF-FT performs in a specific tank or vessel. The simulation gives information on wetting intensity, pattern mesh width and cleaning jet velocity. This information is used to determine the best location of the tank cleaning device and the correct combination of flow, time, and pressure to implement.
