3.1
Description
The Alfa Laval GJ 8 is a fluid-driven (turbine-driven) 360° rotary nozzle machine designed for cleaning the interior surfaces of
a variety of medium to large tanks and vessels. It is powered entirely by the cleaning solution; it requires no electricity,
compressed air or lubricant for operation. The Alfa Laval GJ 8 is designed primarily for portable service; however, the unit
may also be permanently installed in a vessel. If the Alfa Laval GJ 8 is permanently mounted inside a tank, we strongly
recommend inspecting the unit every few hundred hours of operation. (See Chapter 6 - Preventative Maintenance for more
information.)
WARNING: Under no conditions, whatsoever, should the Alfa Laval GJ 8 ever be immersed in anything, unless you
have prior approval from Alfa Laval Tank Equipment, Inc. Failure to comply with this restriction will void the
warranty!
In order to handle the broadest possible range of applications, the stainless steel Alfa Laval GJ 8 is available with dual or triple
nozzles, and an extensive selection of nozzle sizes, stators (non-rotating turbine), and O-ring materials. The nozzles are
available in six interchangeable sizes - 1/4", 9/32", 5/16", 3/8" and 7/16" /(6.3 mm, 7.1mm, 8mm, 9.5mm and 11.1 mm). The
Alfa Laval Gamajet wash cycle time can be adjusted for special applications by changing the stator, and nozzle size.
Interchangeable stators and nozzle sizes are available for either low or high pressures and/or flow rates. A complete
description of the technical specifications and materials of construction of the Alfa Laval GJ 8 is contained in section 8 Parts list
and Service kits.
