Dewatering Pumps

First we have to know some facts for our understanding
Dewatering is always a continuous process of transferring water from area A to area B. Dewatering projects are normally always running 24 hours a day and that too far long periods of time say months together!

Unexpected change in groundwater level during construction works can destroy the complete construction, for example; a basements can completely come out of the ground and will float on the groundwater when the groundwater level is coming up and the construction is not finished!. As soon as we have to use pumps for transferring this flow, it is absolutely important that these pumps are reliable and ask for minimum maintenance. Groundwater flows are not equal w.r.t. the capacity of flow and have quite a lot of natural vagaries which have to be taken care off.

Dewatering is about controlling ground water, which means "FIGHTING" against NATURE!.

Salient Features

• The OEW-IMPULSE IP-series is build for well point dewatering purposes. The pumps are easy to handle, and don’t need a lot of maintenance during running. Those pumps can run dry and will hold the vacuum in the system.


• Instead of a centrifugal, which can not create a vacuum on it’s own. (only the self priming types, but you have to fill up the pump house completely with water, or make it vacuum assisted). The OEW-IMPULSE IP series is a double acting piston pump with a great reliability and can do it’s work without the need of inspection 4 times a day according to flow of water.


• Fuel consuming for the IP 175 (90 m3/h) approx 2 liter / hour!
