Gamajet 4 Tank Cleaning Machine

Gamajet 4 Tank Cleaning MachineOur Most Powerful 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.

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 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. Lubrication, Waterside: A controlled amount of the cleaning solution is permitted to flow through the tee and nozzle housing bearings for lubrication and cooling.

Self-Cleaning Provisions

A low-pressure bypass system keeps the bevel gears and other internal parts flushed free of debris that could interfere with proper functioning.

Nozzles

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.
