Conventional centrifugal residual slurry pump,especially rubber pump,can hardly meet the requirement of small flow and high head.The wear-resistant rubber double-stage pump is characterized by high head equivalent to alloy pumps,good corrosion-resistant performance equivalent to stainless steel pumps and wear-resistant performance equivalent to rubber pumps.The paper introduced the working mechanism,structural performance and application characteristics of the wear-resistant rubber double-stage pump and its application to the tailings transmission and press filtering in a gold mine.It requires less infrastructure investment,is simple to operate and costs less to apply the wear-resistant rubber double-stage pump to tailings transmission.The application to tailings press filtering has achieved the performance of large flow while low head and small flow while large head for the feeding pump,with the filtered cake containing 18 %-20 % water,creating significant economic profits.
