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. |
