CPWE pumps have evolved from a long history of improvements and are designed to be portable, easy, reliable and efficient.  They cater to a wide range of dewatering applications from mines, process water, municipal and general dewatering.  Low weight and high performance becomes a game changer when you have to move pumps to multiple locations.  This is where CPWE pumps make the difference and become a preferred choice of customers.  The modular design helps in servicing the pump with ease. With the inbuilt electrical protections inside a sealed unit, installing the pump is a matter of minutes.  These small things make a difference when you have to be quick and flexible in the field.
