GJ 7 Tank Cleaning

Application

The smallest rotary impingement tank cleaning device, the Alfa Laval GJ 7 easily fits through a 3.8 cm access hole. Capable of operating at both high and low pressures, this device delivers 2.27 kg. of cleaning force at .76 m. 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. 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, every time.

Cleaning Pattern

The above drawings show the cleaning pattern achieved on a cylindrical horizontal vessel. The difference between the first cycle and the full pattern represents the number of additional cycles available to increase the density of the cleaning.
