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.
In order to handle the broadest possible range of applications, the stainless steel Alfa Laval GJ 8 is available with dual or triple nozzles, and an extensive selection of nozzle sizes, stators (non-rotating turbine), and O-ring materials. The nozzles are available in six interchangeable sizes - 1/4", 9/32", 5/16", 3/8"...
Read the instructions carefully and pay special attention to the warnings! Always check the tank cleaning machine before operation. Unpacking/delivery Step 1 CAUTION Check the delivery for: Alfa Laval cannot be held responsible for incorrect unpacking. 1. Complete Cleaning Machine 2. Delivery note Step 2 Remove any packing material Step 3 Inspect the tank cleaning machine for visible transport damage.
Mounting Before mounting the Alfa Laval GJ 8, make sure the supply line has been adequately flushed. It should be mounted on a rigid 1-½” pipe using an adjustable or pipe wrench. In most applications, the Alfa Laval GJ 8 will be mounted in the upright position (inlet connection pointing up);...

Some vessels may have specific cleaning problems such as coils or heavy deposits such as the liquid level line (bathtub ring). In these situations the Alfa Laval Gamajet should be located closer to the difficult area for the best cleaning results.
PD pump with the actual operating pressure. The actual operating pressure is dictated by the fixed flow rate of the pump, the Alfa Laval GJ 8 and the plumbing system. If a PD pump is used, the Alfa Laval GJ 8 should be sized to, first, match the flow capability of the pump and, second, not exceed the pump's maximum operating pressure (taking the pressure rating of the plumbing system into account, also).
Initial Startup Every Alfa Laval GJ 8 that ships is accompanied by a Birth Certificate. This document indicates how the Alfa Laval GJ 8 performed in our testing tank before it shipped based on the operating conditions supplied to Alfa Laval Tank Equipment Inc.
5. Operation Pay attention to possible faults Read the instructions carefully Trouble Shooting - Cracked Input Pinion (pos. 39) - Section 6.4 Inspection and Service of Components Does Rotor (pos. - Damaged planetary gearhead (pos. 13) - Section 6.4 Inspection and Service of 10) turn freely by Components hand?

TIGHT CLEARANCES A newly overhauled Alfa Laval GJ 8 may fail to operate when first returned to service. If the machine seems otherwise fine, try running it with at least one Nozzle Tip removed. The reduction in pressure and additional flow will invariably be enough to overcome the extra resistance of new Bearings and Seals.
5. Operation Pay attention to possible faults Read the instructions carefully Cleaning Solution Leakage - Worn Bearings & Seals Water exiting from the CIP holes in the Tee Housing will cause a slight spray to exit around the Tee and Nozzle Housing. However, excessive leakage from the Tee Housing or Nozzle Housing usually indicates worn Housing Bearings (29), and Seals (31).
- Inadequate Drainage Ensure that the vessel drains the effluent or 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. 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 8.9 Minor Service Kit & 8.10 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 seals and O-rings during prolonged contact in storage.
6. Maintenance Read the instructions carefully. The items refer to the parts list and service kits section. 6.3 General dismantling Step 1 Inlet Collar Loosen the Collar Set Screw (45) with the 1/8" Hex Key. Unthread the Collar (8) and remove the Stator (9). Tip: If (8) does not unthread easily, remove (45) and spray a generous amount of liquid lubricant into the threaded hole.
6. Maintenance Read the instructions carefully. The items refer to the parts list and service kits section. 6.4 Inspection and Service of Components Drawing 1 Stator Inspect all the openings through the Stator (9) to be sure that they are clear and free of debris. Drawing 4, 5 Base Assembly Inspect the Output Pinion (11) and Idler Gears (16) for worn, damaged, or sharp/pointed teeth.

Once dry, the Planetary Gears can be lightly hand - packed with grease. Alfa Laval Tank Equipment recommends using a Chevron FM NLGI 2 grease for food grade applications and a Fuch’s ST-80 grease for aggressive chemical environments.

(30) out of (5). The press tools are available from Alfa Laval Tank Equipment Inc. Before installing new (30), clean the housing bores and remove any burrs resulting from (30) 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. Apply a dab of a Teflon-based anti-seize compound, except when otherwise noted, to all threads when reassembling; this will prevent galling of threads and ease any future disassembly.

6. Maintenance Read the instructions carefully. The items refer to the parts list and service kits section. Drawing 20- 31 Gear Train Turn to (drawing 30): Place the Rotor Shaft (21) assembly partially into the Rotor Shaft Lower Bearing Housing (25). Insert them into the Planetary Gearhead (13), ensuring that the Input Pinion (39) has properly meshed with the gears inside of (13).

TRAX simulation tool TRAX is an unique software that simulates how the Alfa Laval GJ 8 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.
