Originally developed to clean fuel storage tanks, the Alfa Laval GJ 9.2 is ideal for any industrial tank less than 1250 gallons. Designed to fit through standard 2 inch inlets, the device’s powerful rotary jets blast away contaminants, and breaks up the most challenging of residues.
To simplify the tank cleaning procedure further, an AlphaJet version is available – an all-in-one portable system, which includes the necessary pumps and filters for for diesel tank cleaning and fuel polishing.
For Diesel Fuel Tanks: diesel fuel can run right through the GJ 9.2, as a cleaning agent, which saves not only on time, but mitigates contamination concerns and waste disposal.
This is also a fuel polishing machine, however GASOLINE CANNOT be run through this machine. Most other fuel types are acceptable, especially diesel.
Inlet Connection: |
¾ in. NPT-Female, ¾ in. BSP-Female |
Construction/Design: |
Parts are machined from 316-L stainless steel investment castings or bar stock. |
Impeller & Final Shaft: |
For increased wear resistance, the input shaft is plasma-sprayed with a Chromium Oxide coating on stainless steel. |
Shaft & Gearbox Bushings: |
Turbine shaft thrust is absorbed by a Tungsten carbide bushing. Gear bushings are carbon filled polyphenylene sulfide. |
Static Seals: |
O-Ring materials are selected for each application. Viton is standard, with Kalrez available. Other materials can be supplied on special order. |
Dynamic Seals and Bearings: |
Rotary shaft and housing seals/bearings are made from carbon-filled-reinforced polyphenylene sulfide for extra long wear and protection against leakage, abrasion and deposit build-up. |
Nozzles: |
Nozzle sizes from 0.1 in. (2.5 mm) to 0.2 in. (5 mm) |
Drive Mechanism: |
The wash fluid enters the Alfa Laval Gamajet at the inlet collar where it encounters and spins turbine blades. The turbine blades are attached to the top of the drive or rotor shaft. The bottom of this shaft is connected to the inside of a sealed, robust 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 become stainless. This sealed gearhead is located inside the gearbox, which itself is sealed, and thus does not require any lubricant. All internal gearhead parts are hardened sintered steel. |
Lubricant: |
Food-grade grease is inside the sealed gearhead casing. |
