Tank cleaning equipment

GJ 10

There is a way to clean your underground storage tanks

The GJ 10 is the first and only automated tank cleaning machine capable of getting 100% of residual fuel, dirt and sludge out of underground storage tanks.

Designed to fit through standard UST inlets, this lightweight unit is fluid driven and requires no external power supply to clean any size storage tank. Its powerful 360 degree rotary jets blast away contaminants and break up dirt and sludge that can be conveniently vacuumed away.

It's the the only machine small enough to fit into USTs, yet with enough power to clean 100% of the interior. It easily puts the contaminant-laden sludge into solution which allows for complete liquid extraction and thorough tank cleaning.

Using a GJ 10, you can quickly clean the tanks and have them ready to accommodate the next load without the risk of contamination. Responding to the needs of the petroleum and contract cleaning industries, we are the only source for an effective way to fully clean your fuel storage tanks.

Other Specifications

Inlet Connection:

1 1⁄2 in. 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 in. (6.35 mm), 0.312 in. (7.92 mm) and 0.375 in. (9.52 mm) orifice diameters. Other nozzle sizes available upon request.

Drive Mechanism:

The wash fluid enters the GJ 10 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.
