Abstract: The Water-Separated Slurry Pump is a kind of pressure-adding equipment used in slurry pipe transportation，which  is widely applied in tailings pipe transportation.The control system is its core technology and has significant effects on the performance indexes.The composition and working principle of the Water-Separated Slurry Pump wete introduced.The hardware composition of the full automatic control system of the slurry pump was studied.By theoretically analyzing and combined with practical experiences，the control system's fulfillment mechanisms for the relevant control functions were studied，and the fulfilling methods were illustrated.It's proved that，with stable，accurate and fast control characteristic and clear working state display of the slurry pump，the full automatic control system enhanced the pump's lifetime，reduced water lose，decreased working intensity of the operaters.
