Grindex Dewatering Pump: Mega

Electrical submersible 3~ drainage pump

The biggest pump in the drainage range.

The Mega pump is ideal for operation in deep excavations where very high head pumping is needed, such as in open pit mines as well as in underground mines. Other typical applications include quarries and tunneling projects.

Mega is designed to handle pH levels from 6 to 13; zinc anodes are available for extra protection. As this pump is made of cast iron, it is also the right choice for heavy-duty applications in salt water. Grindex reliable pumps are designed for long time operation and are easy to install.

Available in both 50hz and 60hz models
