China Vertical Slurry Pumps 40PV-Sp

SP(R)Vertical Slurry Pump Features:FULLY CANTILEVERED - Eliminates submerged bearings, packing, lip seals, and mechanical sealsSTANDARD IMPELLERS - Unique double suction impellers; fluid flow enters the top as well as the bottom. This design eliminates shaft seals and reduces thrust load on the bearings.LARGE PARTICLE - Large particle impellers are also available and enable passing unusually large solids.BEARING ASSEMBLY - Our maintenance friendly bearing assembly has heavy duty roller bearings, robust bearing housings, and a massive shaft.CASING - The metal pumps have a heavy walled abrasive resistant chrome alloy casing. Rubber pumps have a molded rubber casing adhered to sturdy metal structures.COLUMN AND DISCHARGE PIPE - The metal pump columns and discharge pipes are steel, and the rubber columns and discharge pipes are rubber covered.UPPER STRAINERS - Snap in polyurethane strainers fit in column openings on the smaller sizes and steel strainers on the larger sizes prevent overly large particles and unwanted refuse from entering casing of the pump.LOWER STRAINERS - Bolt on steel strainers on the metal pump and molded snap on polyurethane strainers on the rubber pumps prevent overly large particles and unwanted refuse from entering casing of the pump.
Vertical slurry pump with both rubber liners or metal liners. Rubber can be R08,r26,s31,s42,s21,etc.metal can be A05,a49,a51, or stainless steel material, such as 304SS,316SS,etc. The material selecting is depending on the application, such as the solid hardness, particle size, and the acid of the slurry,ect.
Structural features of Naipu vertical slurry pump(semi-submersible slurry pump):
Vertical type liquid slurry pump is a vertical single-stage single-suction cantilever centrifugal pump structure.The pump body is submerged in the delivered liquid, so there is no need to start with water and the suction problem is solved.There is no seal and no bearing under the liquid part, which overcomes the disadvantages of the old type of seal under the liquid pump, short service life of the bearing and large maintenance workload.The impeller is a semi-open impeller with a stirring blade at the extension of the suction side of the impeller.The front and rear cover plates of the impeller are equipped with vanes to reduce leakage, balance axial force, and improve the service life and operation reliability of the pump.The pump inlet is immersed in liquid, the outlet is tangential vertical upward, and the pump rotates clockwise from the transmission end.The bearing body parts are lubricated with grease, and the amount of oil is within the range of 1/2 to 2/3 of the space volume of the bearing chamber. The bearing is installed in the closed bearing chamber, and the bearing outdoor is sealed with oil seal, so as to prevent dust from entering the bearing chamber and extend the life of the bearing.
Vertical slurry pump is a vertical single-stage single-suction cantilever centrifugal pump structure, impeller is a semi-open impeller, impeller suction side extension is provided with a stirring blade.
Mainly used in environmental protection, municipal works, coal-fired power plants, gas coke plant, oil refineries, steel mills, mining, paper industry, cement factories, food factories, printing and dyeing industries pump thick fluid, heavy oil, diesel, dirty fluid, mud, mortar, sand flow and the flow of the sludge, city PaiWuGou and containing mud residue fluid and corrosive liquids.
