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.
