1,The set are the dry submersible type . the motor use the oil box sealing type , there is mechanical seal inside can protect the high pressure water and impurity coming into the pump channel.
2,Except the main impeller , the pump have a agitation ,can make the sedimentous sand into turbulentflow,then the pump can pumping easily .
3,Ehe materials of pump main impeller and agitation impeller are all high chrome alloy materials ,this kind materials have the features of anti-abrasion ,anti- corrosion ,and large sewage through capability.
4,Ehe pump and motor all working into the water .no limit on the suction head , then can have high efficiency in suction the sand , can dredging sand Thoroughly.
5,The whole set equips are all simplified ,no need the auxiliary .easy to operate .saving cost.
6,The agitation impeller near the sand layer ,can control the medium sand concentration by the pump submerged depth .if the medium too density too large , and add the Auxiliary device to transport high concentration medium.
