Tank cleaning equipment

GJ 5

A fast and easy way to clean small tanks

 

The GJ 5 tank cleaning machine is a fluid-driven, rotary tank cleaning device designed to fit through small passageways and to clean smaller vessels up to 15 ft. (4.6 m) in diameter by 15 ft. (4.6 m) high. The GJ 5's compact size readily passes through a 3 inch opening, making it ideal for cleaning small and mid-sized tanks, vats and vessels.

This device offers the cleaning power and flexibility you need. It surpasses spray balls, water blasting, boil outs, manual hose, and scraping and chipping.

It revolves 360° in both horizontal and vertical planes, with synchronized solid jets providing a tight and thorough scouring pattern on the inside tank surfaces in just one complete cycle. Its horizontal and vertical rotation patterns are interlocked and controlled by gears, not by any reaction forces.

A choice of nozzle sizes and stators offers a range of flow rates, pressures and wash cycle times.

Other specifications

Inlet Connection:

1 1/4 in. NPT-Female, 1-1/4 in. BSP Female, TC sanitary inlets are available

Construction/Design:

Parts are machined from 316-L stainless steel investment castings or bar stock.

Impeller & Final Shafts:

For increased wear resistance, the impeller is plasma-sprayed with a chromium oxide coating on stainless steel.

Shaft & Gearbox Bushings:

Turbine shaft thrust is absorbed by a Tungsten carbide bushing. Gearbox bushings are carbon-filled Teflon or other non-cupric material.

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:

Rotary shaft and housing seals are spring-loaded, double-lipped and made of PTFE. They are reinforced for extra-long wear and protection against leakage, abrasion and deposit build-up.

Nozzles:

Dual 0.125 in. (3.28 mm), 0.135 in. (3.4 mm), 0.15 in. (3.8 mm), 0.165 in. (4.2 mm), 0.187 in. (4.8 mm), 0.2 in. (5.1 mm) and 0.225 in. (5.7 mm) orifice diameters. Short and long nozzles available. Other nozzle sizes available upon request.

Drive Mechanism:

The wash fluid enters the GJ 5 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, 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 for added corrosive 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 lubricant is inside the sealed gearhead casing. No customer-supplied or user-maintained lubricant can be substituted.
