Alfa Laval GJ 9

A quantum leap in tank cleaner durability, efficiency, and price, the Alfa Laval GJ 9 is a totally new tank cleaning system. The Alfa Laval GJ 9 offers compact cleaning for small and mid-sized tanks with fewer parts. The highly durable design provides superior performance at an affordable price, making it the ultimate tote washer. There are less parts, which means the GJ 9 should have fewer breakdowns and lower maintenance costs. Coupled with Alfa Laval's renowned product quality, the built-in durability allows the GJ 9 to be used in rugged applications in even the harshest environments.

The Alfa Laval GJ 9, like other Gamajets, is a high quality tank cleaning machine. Originally designed for tote cleaning applications, the Alfa Laval GJ 9 tank cleaning machine is perfect for other small and mid-sized tank cleaning applications. Its 360° spray pattern provides thorough scouring of the entire tank or tote, reducing operating time and costs. At an unbelievably low price, the Alfa Laval GJ 9 sets the standard for cost-effective impingement tank cleaning and tote washing.


The Alfa Laval GJ 9 is part of the world-renowned Gamajet range of high impact tank cleaning devices. The device offers compact cleaning for small tanks, totes, and intermediate bulk containers (IBCs) in both industrial and hygienic applications. With fewer parts and a highly durable design, the Alfa Laval GJ 9 provides superior performance and is the most versatile rotary jet head available. This device readily passes through three inch openings and can handle high pressures and temperatures, enabling quick and easy cleaning of small totes/IBCs, tanks, trash carts, and much more. Companies are able to clean in-house, saving a substantial amount of time, water, and money.


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.


The choice of nozzle diameters can optimize jet impact length and flow rate at the desired pressure. As standard documentation, the Alfa Laval GJ 9 can be supplied with a “Declaration of Conformity” for material specifications.
