The Alfa Laval GJ 7, Alfa Laval GJ BB and Alfa Laval GJ 9 rotary jet head tank cleaning devices represent a major technological breakthrough, offering the most powerful cleaning results in a compact, easy to handle size. The Alfa Laval GJ 7 and Alfa Laval GJ BB are specially designed to clean small barrels and drums, while the Alfa Laval GJ 9 offers fast cleaning of your intermediate bulk containers (IBC). All devices are available in a wide range of sizes and nozzle configurations.
Gamajet 7 (GJ7)
The Alfa Laval GJ 7 tank cleaning machine is a small, powerful unit that is ideal for cleaning all types of barrels, drums, and small vessels. It eliminates extensive handling by offering one-step, one-insertion cleaning. The Alfa Laval GJ 7 delivers fast, effective cleaning that is complete in less than two minutes. It works especially well in tough cleaning situations involving wine, paint, and other difficult materials.
The combination of rugged, long-lasting design, powerful jet spray cleaning, and field serviceability have long made Gamajet the first choice for cleaning among the world’s best known companies. The Alfa Laval GJ 7 represents a major technological breakthrough, offering the most powerful cleaning in a compact size. It is capable of running with the pressure and flow of a standard pressure washer.

Smallest rotary impingement tank cleaner: 1.5 inch (38 mm) clearance
Operates at both high and low pressures
Powerful: 5 lbs (2.5 kg) of cleaning force at 2.5 feet (0.75 m)
Application
The smallest rotary impingement tank cleaning device, the Alfa Laval GJ 7 easily fits through a 1 ½ inch access hole. Capable of operating at both high and low pressures, this device delivers five pounds of cleaning force at 2 ½ feet. The Alfa Laval GJ 7 offers quick and easy cleaning of barrels, drums, and other small vessels in a wide variety of industries. The device is part of the world-renowned Gamajet range of high impact tank cleaning devices.
Working Principle
The Gamajet range of high impact tank cleaning devices combine pressure and flow to create high impact cleaning jets. Cleaning occurs at the point at which the concentrated stream impacts the surface. This impact, and the tangential force that radiates from that point, blasts contaminants from the surface, scouring the tank interior. In conjunction with this impact, the device is engineered to rotate in a precise, repeatable, and reliable 360° pattern. This full-coverage, global indexing pattern ensures the entire tank interior is cleaned, every time.
Standard Design
The choice of nozzle diameters can optimize jet impact length and flow rate at the desired pressure. As standard documentation, the Alfa Laval GJ 7 can be supplied with a “Declaration of Conformity” for material specifications.
Options
Electronic rotation sensor to verify 3-D coverage.
Caution
Technical Data
The Alfa Laval GJ 7 rotary jet head delivers a high-impact jet stream that reaches every part of the interior surface of a drum or barrel in an increasingly dense cleaning pattern. This provides powerful mechanical cleaning using minimal water and cleaning media.
The flow of cleaning fluid powers the nozzles, rotating them in a geared motion around both vertical and horizontal axes. During the first cycle, the nozzles create a coarse cleaning pattern on the surface. With each subsequent cycle, the pattern becomes denser until the full cleaning pattern is achieved. Once complete, the machine repeats the process, delivering consistent, thorough cleaning.

4106-0368 — Full cleaning pattern
The illustrations above show the cleaning coverage in a cylindrical horizontal vessel. The difference between the first cycle and the full cleaning pattern reflects the number of additional cycles required to achieve maximum cleaning density.
