Alfa Laval GJ 8

The Alfa Laval GJ 8 provides the same flow as traditional, larger tank cleaners, but this new unit is lighter, shorter, and narrower for easier entry and maneuverability. It offers unparalleled ease of handling in a wide variety of tank cleaning applications.

The Alfa Laval GJ 8 does not require any power assists, because it is smaller in diameter than any other fluid driven unit with similar flow characteristics. It fits through small openings, while maintaining the flow required to clean larger vessels. The light weight and smaller size of the GJ 8 makes it easy to move and handle. The versatility of the pressure and flow of this machine makes it ideal for most large tank cleaning applications.


Designed with ergonomics in mind, the Alfa Laval GJ 8 provides the same high impact clean as traditional, larger tank cleaners but is lighter, shorter, and narrower. This device is part of the world-renowned Gamajet range of high impact tank cleaning devices and is the perfect alternative to heavy impingement cleaners, time-intensive spray balls, and costly manual tank cleaning. Compact and efficient, the Alfa Laval GJ 8 allows for space saving, while maintaining the impact, durability, and range required for optimal impingement tank cleaning. This device is fluid-driven, eliminating the need for power assistance and is ideal for cleaning stubborn residues in large tanks in a variety of industries such as ethanol, paper, pulp, chemical, steel, industrial fermentation, and applications requiring high impact cleaning.


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 8 can be supplied with a “Declaration of Conformity” for material specifications.
