but are highly-engineered to deliver increased force. Water forced through rotary jet nozzles rotates the device on a dual axis, creating a 360° cleaning pattern. As the water sprays, the liquid is pumped out of the tank. Portable cleaning systems are commonly used for many outdoor applications while

However, with
Gamajet tank cleaning machines, confined space entry is greatly reduced eliminating danger to workers. Manual tank cleaning is dangerous in a number of ways. While tank barges can be cleaned in port, shipboard tanks are generally cleaned at sea. This is largely due to risks of fire and

The
Butterworth Type K machine is widely used. This model can clean a tank of up to 10,000,000 US gallons (38,000 m). It uses water with a pressure up to 250 psi (1,700 kPa) and a temperature of up to 250 °F (121 °C). The water jet reaches up to 115 feet (35 m).

Depending on the pressure used, a cleaning cycle can take from about 10 to 50 minutes and the machine uses between 15 US gallons (56.8 L; 12.5 imp gal) and 350 US gallons (1,324.9 L; 291.4 imp gal) per minute.
