LMU corrosion resistant abrasive slurry pump
Product overview
LMU slurry pump is a cantilever type single-stage single-suction centrifugal pump, which is specially designed and developed by our factory for conveying corrosive media containing fine particles. The pump is made of steel lined ultra-high molecular weight polyethylene (uhmw-pe), which has strong corrosion resistance and excellent performance wear resistance, can be widely used in a variety of corrosive abrasive slurry conveying process.
Design feature
Strong wear resistance: The flow parts are all made of steel lined ultra-high molecular weight polyethylene (uhmw-pe), ultra-high molecular weight polyethylene (uhmw-pe) has excellent abrasion resistance, 4 times higher than nylon 66(pa66), polytetrafluoroethylene (PTFE), is carbon
7-10 times the wear resistance of steel and stainless steel.
Strong impact resistance: The impact strength of ultra-high molecular weight polyethylene is also very good, is 5 times that of (acrylonitrile/butadiene/styrene) copolymer (abs), and can remain stable at -196 ° c, which is not a feature of any other plastic.
Excellent corrosion resistance: The pump in a certain temperature and concentration range can resist a variety of corrosive media (acid, alkali, salt), in 20℃~90℃ 80 kinds of organic solvents impregnation 30d, appearance without any abnormal phenomenon, other physical properties are almost no change.
Ultra-high molecular weight polyethylene impact absorption is very good in plastics, good noise reduction.
Safe and reliable, no toxin decomposition, so it is also suitable for the food industry.
The coefficient of friction is low, only 0.07-0.11, so it has self-lubrication. Under the condition of water lubrication, its dynamic friction coefficient is half lower than pa66 and pom. When working in sliding or rotating form, the lubricity is more ideal than that of steel and brass after lubricating. Therefore, it is rated as a wear-resistant material with "Very ideal cost/performance".
Main use
(1) sulfuric acid phosphate fertilizer industry: Dilute acid, mother liquor, sewage, seawater, silica-containing fluorosilicic acid, phosphate slurry and other media transportation.
(2) non-ferrous metal smelting industry: Especially suitable for lead, zinc, gold, silver, copper, manganese, cobalt, rare earth and other wet smelting of various acid, corrosive pulp, slurry (filter press) electrolyte, sewage and other media transport.
(3) chemical and other enterprises: All kinds of sulfuric acid, hydrochloric acid, alkaline, oil clear liquid or slurry positions. Titanium dioxide, iron red powder production, various dyes, pigment production, non-metallic mineral processing and other industries.
(4) chlor-alkali industry: Hydrochloric acid, liquid alkali, electrolyte, etc.
(5) water treatment industry: Pure water, high purity water, sewage (leather sewage, electroplating sewage, electronic sewage, paper sewage, textile sewage, food sewage, domestic sewage, pharmaceutical industry sewage, etc.).
(6) iron and steel enterprises: Sulfuric acid, hydrochloric acid post of pickling system, sewage with impurities.
(7) wet desulfurization circulating pump: Can be applied to alkaline, acidic, corrosive positions at the same time.
(8) transportation of corrosive liquids and coal slurry in coal industry and coal chemical industry; pump for coal washing and preparation.
(9) can not transport strong oxidizing acids (such as concentrated sulfuric acid and nitric acid), can not transport solvent media (such as benzene)
