Directional 4 Tank Cleaning

Need to clean the bottom of a tank fast and effectively? Look no further than the NEW Gamajet Bullet IV for tough, targeted cleaning of sludge, oil, grease, fat, and other residual debris that collects at the bottom of open-top tanks, process vessels, trailers, barges, and rail cars. The Gamajet Bullet IV rotates in a tight 105-degree downward pattern, with high impact water jets scouring the bottom area of the tank. Built with durability, strength, and performance in mind, residual heels don’t stand a chance against this machine.

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

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.
