A submersible pump (or sub pump, electric submersible pump (ESP)) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in the fluid to be pumped. The main advantage of this type of pump is that it prevents pump cavitation, a problem associated with a high elevation difference between pump and the fluid surface. Submersible pumps push fluid to the surface as opposed to jet pumps having to pull fluids. Submersibles are more efficient than jet pumps.

Submersible slurry pump is a kind of centrifugal pump, and play an important role in solids control system. KOSUN Submersible Slurry Pumps are mainly used for environmental protection, new type building materials , coal washing , municipal projects, thermal power generation, coal gas coking plant,refinery,steel mills,mining,paper making,cement plant,food products factory and other fields to perform pumping of thick oil, oil residue, dirty oil, mud, mortar, running sand and other liquids from the municipal sewerage. It is also suitable for pumping liquids with silt particle and corrosive liquid.

KOSUN Series Submersible slurry pump is with structure of vertical single stage and single suction system overhung centrifugal pump, it is made of abrasion-resistant alloy, it can transfer medium with high concentration particle. The normal submersible length is 1.3m/1.5m, customized length is available. There is no bearing and Gland Seal between impeller and pump body, so the slurry pump is maintenance-free and high temperature resistance, the slurry pump is the ideal centrifugal pump for feeding to decanter centrifuge, and feeding from mud pit for to the shale shakers on the mud system, it can also be used as feeding pump for desander , desilter and centrifuge.

Submersible slurry pump bearing short life is due to friction in pump, impeller unbalanced, foreign body in bearing, unreasonably equip bearing, center shaft is tortuous. Solutions are adjust impeller balance or replace new impeller, clear bearing foreign body, equip bearing again, change center shaft.

KOSUN is a professional solids control manufacturer in China.Except submersible slurry pump,KOSUN provides other pumps,including shear pump,Centrifugal Pump,Screw Pump,etc.Solids control equipments and different complete solids control system is also included.
