Gamajet 4 Tank Cleaning Machine
Our largest automated tank cleaner, the Gamajet IV “GT” tank cleaning machine is designed to clean larger-sized tanks with diameters of over 15′ (4.57 m). Developed and upgraded from the proven Gamajet III, the IV “GT” 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 IV “GT” 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 IV GT offers a wide operating range of flow rates, nozzle rotation speeds, and wash cycles. The IV “GT” is fully capable of high concentration chemical recirculation cleaning or high pressure/low volume water jet scrubbing in fixed CIP automated systems.

Construction / Design
New Features: Streamlined turbine and internal flow passages, including a patented porting design that significantly improves efficiency.
Investment cast parts of type 316 stainless steel ensure consistent strength & quality for higher pressure ratings. Shafts: Rotor shaft and gearbox shafts are made of hardened stainless steel. For increased wear resistance, the rotor shaft is supplied with a plasma-sprayed ceramic or other protective coating. The rotor shaft is also fitted with a polished carbide thrust washer for added durability.
Rotor shaft bearings are tungsten carbide. Gearbox shaft bearings in flo-thru (oilless) gearboxes are PTFE or other non-cupric materials. Standard bearings in oil-lubricated gearboxes are Oilite bronze with nonmetallic bearings available as an option.
O-ring materials are selected for each application. Viton is standard. Drive Gears: A new gear system of improved design and construction is incorporated in Gamajet IV “GT” models for increased wear life: All gears are manufactured entirely of selected stainless steel alloys and the two bottom gears are fitted with long-life tungsten carbide thrust washers.
Sealed: Oil-lubricated machines have a sealed gearbox filled with FDA approved oil. Flo-thru: The flo-thru gearbox is lubricated by the cleaning solution. With this option, maintenance of gearbox seals is eliminated. Lubrication, Waterside: A controlled amount of the cleaning solution is permitted to flow through the tee and nozzle housing bearings for lubrication and cooling.
A low-pressure bypass system keeps the bevel gears and other internal parts flushed free of debris that could interfere with proper functioning.
Interchangeable nozzles are now available in twelve sizes from 5/8″ (15.9mm) down to .177″ (4.5 mm). Nozzle sizes of 1/4″ (6.35 mm) and smaller are offered with new tungsten carbide inserts for improved jet wear at high pressures.
