Gamajet Powerflex Tank Cleaning Machine

Gamajet Powerflex Tank Cleaning MachinePowerful, Sanitary Tank Cleaning for a Variety of Pressures and Flows

The Gamajet PowerFlex tank cleaning machine was specifically engineered to offer the most efficient and effective cleaning for vessels with capacities of 5,000 to 25,000 gallons. The durable machine offers optimal cleaning at a variety of pressures and flows.

The sanitary design of the PowerFlex makes it ideal for use in food & beverage, pharmaceutical and personal care industries, for both portable and permanent applications. The standard machine is self-cleaning, self-flushing, and self-lubricating, requiring no oil or grease in the gear train.

However, a grease-lubricated version is available as an option. All components of the PowerFlex are made from FDA compliant materials.

The key to the PowerFlex’s versatility and durability is the use of an oversized gear head that efficiently generates the proper torque to rotate the unit. The larger components last 20-30% longer than traditional drive mechanisms, making the PowerFlex our most durable design to date.

The large gear reduction allows the PowerFlex to operate at lower pressures and higher flows when compared to other tank cleaning machines.

Like other Gamajet tank cleaning machines, the PowerFlex uses the same proven Gamajet impingement cleaning pattern, scouring 100% of the tank, every time.

Other Specifications

Inlet Connection

1.5″ Tri-Clover, 1.5″ slipfit (R-clip), 1.5″ NPT-Female, 2″ Camlock Plug 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 food grade polyphenylene sulfide. Elastoners: O-Ring materials are selected for each application. EPDM is standard, with Viton and Kalrez available. Other materials can be supplied on special order.


Nozzle sizes from 1/4″ (6.35 mm), 5/16″ (7.94 mm) to 3/8″ (9.53 mm)
Drive Mechanism: The wash fluid enters the 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 flo-thru, robust planetary gearhead which then turns the body in the horizontal plane and the nozzles in the vertical plane.

Planetary Gearhead

The flo-thru planetary gearhead uses the wash fluid as a lubricant. All internal gearhead parts are stainless steel. Operating & Maintenance: Complete operating and maintenance procedures are covered in a detailed instruction manual furnished with all machines.

Ready availability of spare parts or kits, and ease of on-site maintenance minimizes the need for repairs. Prompt factory overhaul or repair service is always available. Replacement parts are stocked year round. Special 24-48 hour delivery available upon request at no extra charge.


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, bearings, bushings 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. For full details, see Gamajet “Terms and Conditions of Sale”.
