Clean Your 30 and 55 gallon drums in minutes


Often used to store and ship dangerous liquids and powders, 30 and 55 gallon drums must be efficiently and effectively cleaned to avoid contamination and spoilage. Drum cleaning must be performed quickly, and with as little manpower as possible so companies can spend less time cleaning and more time producing. As its name implies, the Alfa Laval GJ BB includes everything needed to easily clean these containers. No other cleaning method provides the convenience, power and low flow capabilities.

Say good-bye to costly and time-consuming outsourcing. Cleaning can be done effectively and efficiently with the Alfa Laval GJ BB ensures the entire drum interior is thoroughly cleaned, while utilizing the least amount of time, energy, chemicals, and water.

The Alfa Laval GJ BB is designed for operation at flow rates as low as 3 gallons per minute. Simply invert the drum or barrel and with a single insertion, 100% cleaning effectiveness is assured.

The Alfa Laval Gamajet BB cleaning machine combines high performance impingement cleaning for barrels and drums through a 2" or larger bung.

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.

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. EPDM is standard with Kalrez and Viton available. Other materials can be supplied on special order.

Dynamic Seals and Bearings

Rotary shaft and housing seals/bearings 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.


Standard nozzle sizes 0.060 (1.5 mm), 0.070 (1.7 mm) 0.075 (1.9 mm), 0.080 (2.0 mm).Other nozzle sizes are available upon request.

Drive Mechanism

The wash fluid enters the GJ BB 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.


 Food grade grease is inside the sealed gearhead casing.
