Valve solutions for mine dewatering systems

A significant amount of energy is required to dewater mining shafts from fissure and service water. One type of Demand Side Management initiative on a mine dewatering system is load shifting. Sustainability necessitates the full automation of the dewatering system to realise the full potential of load management savings. Automation often requires major instrumentation infrastructure changes such as discharge valve actuation and vibration, as well as flow and pressure monitoring of a multistage pump. Discharge valve actuation is critical for pump performance and operation as well as theremote stop and start capabilities. Special attention must be given to selecting the most suitable valve and actuator combination. Incorrect valve selection can result in reduced pump efficiency.
