Large Capacity Sand Suction Dredging Pump

Brief Introduction

Sand suction dredging pump is mainly used for continuous transportation of highly abrasive materials which are too large to be transported by normal slurry pump. This sand suction dredging pumps are mainly horizontal centrifugal pumps with single pump covering structure. The special clamp is used for fixing the pump body and the pump casing. It is easy to install and use.
