This is also a fuel polishing machine, however GASOLINE CANNOT be run through this machine. Most other fuel types are acceptable, especially diesel.  

Other Specifications: 

Inlet Connection: 1 1⁄2" NPT-Female.

Construction/Design: Parts are machined from 316-L
Stainless Steel investment castings or bar stock.

Impeller & Final Shaft: For increased wear resistance, the rotor shaft is plasma-sprayed with a Chromium Oxide coating on Stainless Steel.

Shaft & Gearbox Bushings: Rotor shaft thrust is absorbed by a Tungsten carbide bushing. Gearbox bushings are also Tungsten carbide.

Bearings: Bearings in the rotating tee and nozzle housings are self-lubricating, carbon-fiber-reinforced polyphenylene sulfide.

Bearing Cups: Main body castings are protected by replaceable 316-L Stainless Steel cups for extended frictional wear life.

Static Seals: O-Ring materials are selected for each application. Viton is standard with Kalrez and EPDM available. Other materials can be supplied on special order.

Dynamic Seals: Dynamic shaft seals are spring-loaded, double-lipped and made of PTFE. They are reinforced with carbon fiber for extra long wear and protection against leakage, abrasion and deposit build-up.

Nozzles: Dual 0.250” (6.35 mm), 0.312” (7.92 mm) and 0.375” (9.52 mm) orifice diameters. Other nozzle sizes available upon request.

Drive Mechanism: The wash fluid enters the Gamajet at the inlet collar where it encounters and spins rotor blades. The rotor blades are attached to the top of the rotor shaft. The bottom of this shaft is connected to the inside of a sealed, planetary gearhead which then turns the body in the
horizontal plane and the nozzles in the vertical plane.

Planetary Gearhead: The sealed planetary gearhead has an external casing made of steel, surface-anodized to increase corrosion resistance. This sealed gearhead is located inside the gearbox, which itself is sealed, and thus does not require any lubricant. All internal parts are hardened sintered
steel, the end caps and the output shaft are stainless steel.

Lubricant: A food grade grease is inside the sealed gearhead casing. No customer-supplied or user-maintained lubricant is needed.

Warranty: Gamajets are warranted for eighteen months from the date of shipment against any defects in workmanship or materials. Normal maintenance parts such as O-rings and bearings and are not included under this warranty, nor is damage caused by dropping, use of destructively corrosive fluids, or other abuse. This warranty shall not apply to any malfunction resulting from use of non-Gamajet replacement parts purchased from any source other than Gamajet or an authorized Gamajet distributor.
