GJ 4

Product Description

Our most powerful industrial tank cleaning machine
Our largest industrial tank cleaner, the GJ 4 tank cleaning machine is designed to clean larger-sized tanks with diameters from 15 to 100+ ft. (30+ m). Developed and upgraded from the proven Gamajet III, the GJ 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 GJ 4 is available in stainless steel 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 GJ 4 offers a wide operating range of flow rates, nozzle rotation speeds, and wash cycles. The GJ 4 is fully capable of high concentration chemical recirculation cleaning or high pressure/low volume water jet scrubbing in fixed CIP automated systems.

Other Specifications
 
Construction / Design: New features: Streamlined turbine and internal flow passages, including a patented porting design that significantly improves efficiency.
Castings: 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.
Bearings, Shaft: 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.
Seals, Static: 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 durability.
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.
Lubrication, Gearbox: 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.
