Gamajet 5 Tank Cleaning Machine

Gamajet 5 Tank Cleaning MachineA Fast and Easy Way to Clean Small Tanks

The Gamajet V’s compact size readily passes through a 3 inch opening, making it ideal for cleaning small tanks, vats and vessels. Gamajet V Tank Cleaning Machine offers the cleaning power and flexibility you need.

It surpasses spray balls, water blasting, boil outs, manual hose, and scraping and chipping.The Gamajet V Tank Cleaning Machine is a fluid-driven, rotary tank cleaning machine designed to fit through small passageways and to clean smaller vessels (up to 15′ (4.57 m) in diameter by 15′ (4.57 m) high).

It revolves 360° in both the 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, turbines and gear speeds offers a range of flow rates, pressures and wash cycle times.

Other Specifications

Inlet Connection

  • 1 1/4″ NPT-Female, TC sanitary inlets are available.


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

Impeller & Final Shafts

For increased wear resistance, the impeller and final shafts are 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 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.


Dual 0.125″ (3.18 mm), 0.135″ (3.43 mm), 0.150″ (3.81 mm), 0.165″ (4.19 mm), 0.187″ (4.75 mm), 0.200″ (5.08 mm) and 0.225″ (5.72 mm) orifice diameters. Longer nozzles available. Other nozzle sizes available upon request.

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 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 become stainless. 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.


A food-grade lubricant is inside the sealed gearhead casing. No customer-supplied or user-maintained lubricant can be substituted.

Gear Ratios

236:1 planetary gearhead supplied.
