2 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! 2.1 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.
The Alfa Laval GJ 10 is designed for both portable and CIP (Clean in Place) applications. If the Alfa Laval GJ 10 is permanently mounted inside a tank, we strongly recommend inspecting the unit every few hundred hours of operation.

PD pump with the actual operating pressure, the actual operating pressure is dictated by the fixed flow rate of the pump and the Alfa Laval GJ 10 / plumbing system. If a PD pump is used, the Alfa Laval GJ 10 should be sized to, first, match the flow capability of the pump and, second, not exceed the Alfa Laval GJ 10’s or pump's maximum operating pressure (taking the pressure rating of the plumbing system into account, also).
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 10 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 time.
5 Operation Pay attention to possible faults Read the instructions carefully 5.2 Trouble Shooting Cracked Input Pinion (pos. 56) – Section 6.4 Inspection and Service of Components Does Rotor Damaged Planetary Gearhead (pos. 12) – Section 6.4 Inspection and Service of (pos.
Insufficient Flow The Alfa Laval GJ 10 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 (8) size is too small and/or the opening at the bottom of the Stator (10) is too large, the Tee Housing (4) 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.
5 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. 5.5 Recommended Cleaning Step 1 Caustic danger! Always handle lye and acid with great care.
Always read the technical data thoroughly. (see chapter 7 Technical Data) Step 2 Recommended spare parts: Order service kits from the service kits list (See 8.10 Minor Service Kit & 8.11 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.
Maintenance Read the instructions carefully. The items refer to the parts list and service kits section. 6.3 General Dismantling Step 1 Inlet Collar If used, loosen the Grounding Set Screw (33) with a 5/64” Hex Key, minimum 2 turns. Remove grounding / safety wire from loop.
The Bottom and Top Stage Planetary Gears (61) and (60) must be reinstalled in their respective locations. The Mid-Stage Planetary Gears (62) are interchangeable, however. During reassembly, Alfa Laval Gamajet Equipment recommends the Gearhead Assembly (drawing 4) be lightly repacked using food-grade grease. Please contact Alfa Laval Gamajet Equipment for a specific grease recommendation.

TRAX Simulation Tool TRAX is a unique software that simulates how the Alfa Laval GJ 10 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.
