摘要： Pumping system with a desilting arrangement having a bidirectional water pump disposed in a housing which has a pump inlet and a pump outlet. The system also has a silt blow-out pipe with a desilting valve therein, connected at one end to the pump outlet and having the other end spaced a certain distance away from the pump inlet and below the water level. Desilting is performed by opening the desilting valve and operating the pump in reverse direction for blowing silt, accumulated at the pump outlet, away.
