Alfa Laval GJ PF

The Alfa Laval GJ PF tank cleaning machine is specifically engineered to offer the most efficient and effective cleaning for vessels with capacities of 5,000 to 25,000 gallons. The durable machine offers optimal cleaning at a variety of pressures and flows.

The sanitary design of the Alfa Laval GJ PF makes it ideal for use in food, beverage, pharmaceutical, and personal care industries, for both portable and permanent applications. The standard machine is self-cleaning, self-flushing, and self-lubricating, requiring no oil or grease in the gear train. However, a grease-lubricated version is available as an option. All components of the PowerFlex are made from Food and Drug Administration (FDA) compliant materials.


The field-proven Alfa Laval GJ PF is part of the world-renowned range of Gamajet high impact tank cleaning devices. It has been proven to provide companies with up to 85% in water, time, energy, and resource savings compared to static spray balls. This device is capable of cleaning tanks with capacities between 5,000 - 25,000 gallons.

The Alfa Laval GJ PF fits through openings as small as four inches and operates at low pressures and flows, cleaning tanks in applications that require high impact cleaning, such as in the ethanol, paper, pulp, chemical, steel, and industrial fermentation industries. By implementing this device into their tank cleaning process, companies spend less time cleaning and more time producing.

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. It is this impact and the tangential force that radiates from that point which 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.
