Javarex Pumps

Javarex is importing the KZN pumps.
These range of pumps are used in heavy duty applications.

These pumps are used in following industries:

• - Sand/gravel extraction
• - Concrete production especially in recycling of concrete
• - Coal mining
• - Stone and brick factories, pumping sandy water
• - Contractor jobs pumping bentonite mud at drilling and diaphragm wall jobs
• - Cleaning water in- and outlets at power stations
• - Fruit/potatoes washing
• - Steel production pumping water with ferro oxides
