• The stirring impeller on the top of the pump will come into direct contact with the depositional surface. It is capable of controlling the sand concentration in the conveyed media through a diving depth.
• Due to the underwater operation of the pump and drive, the suction head is not limited, and features a highly efficient sand absorption and thorough dredging.
• Impeller, stirring impeller and other main wet ends are manufactured with a highly wear resistant and corrosion resistant material.
• Operation is simple, and the pump requires no auxiliary vacuum pump or stirring device.
• The driver submerges into water, and requires no grounding for fixing devices, which saves installation costs.
• Triple protection: oil chamber flooding detection and alarm, motor chamber flooding detection and alarm, motor overheating detection and alarm

Quick selection chart Service conditions

• The normal power supply is 50Hz/380V three-phase AC power supply. In addition, 400V, 440V, 660V, 1140V and other power supply can be customized.
• The maximum temperature of the medias should not exceed 60℃. If not so, the pump should be coated with cooling sets and cooled by external water.
• The maximum allowable concentration of the solid particles in the mediums is 45% for ash and 60% for slag.
• The diving depth of the pump unit should be no more than 20m and no less than 1m.
