Alfa Laval’s Most Powerful Tank Cleaning Machine
ABS offers the largest automated tank cleaner from Alfa Laval, the Alfa Laval Gamajet 4 tank cleaning machine is designed to clean larger-sized tanks with diameters of over 15 feet (4.57 m). Developed and upgraded from the proven Gamajet III, the Gamajet 4 is a hydraulically driven rotary tank cleaning machine that revolves 360° in both horizontal and vertical planes. Synchronized solid jets provide a tight and thorough scouring pattern covering all interior tank surfaces in one complete cycle.
The Gamajet 4 is available in stainless steel or silicon bronze with a choice of oil-lubricated or flow-thru (wash fluid lubricated) gearboxes. Gear trains are designed to maximize wear life which offers improved reliability and reduced downtime.
With a choice of twelve nozzle sizes, various hydraulic turbines and stators along with two gear systems, the Gamajet 4 offers a wide operating range of flow rates, nozzle rotation speeds, and wash cycles. The Gamajet 4 is fully capable of high concentration chemical recirculation cleaning or high pressure/low volume water jet scrubbing in fixed CIP automated systems.

Application
The Alfa Laval GJ 4 is part of the world-renowned Gamajet range of high impact tank cleaning devices. The device provides high-impact cleaning for large-sized tanks with diameters over 15 feet. The Alfa Laval GJ 4 is designed to remove the toughest residues from large tanks in numerous industries and is customizable in a wide variety of ways. The Alfa Laval GJ 4 allows companies to 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. 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 4 can be supplied with a “Declaration of Conformity” for material specifications.
Options
Electronic rotation sensor to verify 3-D coverage. 180° and 105° directional versions are available.
Caution: Do not use for gas evacuation or air dispersion.

A quality product
The Alfa Laval GJ tank cleaning devices are part of our highly acclaimed Gamajet product range. Alfa Laval technology combines pressure and flow to create high impact cleaning jets that are precision engineered to rotate in a precise, repeatable and reliable 360-degree pattern.
Positive return on investment
The unique design reduces your cost to clean and environmental footprint by minimizing the amount of water, energy and cleaning agents required to clean tanks. Using high-impact jet cleaning instead of traditional ineffective static spray ball reduces waste and resource consumption.
Retrofit old spray ball
Due to the physical size of the Alfa Laval GJ PF, it is now possible to upgrade your cleaning device to a more efficient solution. The low profile Alfa Laval GJ PF fits though a 4 inch connection, making it possible to install the device into an existing tank top connection.
Validate your tank cleaning process
Alfa Laval Rotacheck validates the rotary jet heads cleaning process, reduces water consumption and product loss. Provides peace of mind.
High-impact, low-resource cleaning
The high-impact jet stream from the rotary jet head is preprogrammed to cover the inside of the tank in a continually denser pattern. This achieves a powerful mechanical impact with a low volume of water, acid or caustic. Most of the GJ rotary jet heads are capable of operating at both high and low pressures.
Smoother, long-lasting performance
The Alfa Laval GJ range includes a unique, grease-lubricated gear to ensure that potentially damaging particles are not trapped in the gear during CIP recirculation. This innovative design ensures a smoother performance and reduces wear and tear.
Energy-efficient design
A faster tank cleaning cycle also cuts energy consumption. Cleaning fluid flows through the nozzles in an automated, geared rotation around the vertical and horizontal axes. In the first cycle, the nozzles lay out a coarse pattern on the tank surface, with subsequent cycles progressively densifying the pattern over the course of eight cycles.
