Mortar pump

Mortar pump

The mortar pump is a cantilevered single-stage, single-suction centrifugal pump, and its flow-passing parts adopt a steel-lined ultra-high molecular weight polyethylene structure, which has strong corrosion resistance and excellent wear resistance. It can transport various kinds of acid, alkali, salt slurry of sulfuric acid below 80%, nitric acid below 50%, hydrochloric acid, etc., various corrosive mortars in the rare metal smelting industry and various mixtures in the food sprinkling industry. Type medium. Mortar pumps are also widely used in desulfurization systems and have excellent effects.

1. Brief introduction of corrosion-resistant and wear-resistant mortar pump
Corrosion-resistant and wear-resistant mortar pump series products are specially designed to transport media with certain corrosiveness and containing fine particles or crystals. They are manufactured by the steel-lined ultra-high molecular weight polyethylene compression molding process. They have excellent corrosion resistance and excellent performance. Wear resistance, the structure is designed as a cantilever front opening type, the impeller is semi-open type (without front cover), which enhances the passage in the flow channel, so that particles and impurities in the medium can quickly pass through the pump cavity without clogging. The seal is a K-type fluorine rubber sealing ring with a cooling water jacket, which takes into account the dual requirements of corrosion resistance and wear resistance. This series of products are well received by users in the metal smelting, titanium dioxide, fine chemical, fertilizer and other industries. In addition, fluorine plastic lining can be used according to customers' special corrosion resistance or temperature resistance requirements, and non-standard models with special flow and head can also be customized.

2. the characteristics of mortar pump
Corrosion-resistant and wear-resistant mortar pump is a kind of pump that can adapt to various working conditions, such as transporting acid, alkaline clear liquid or slurry; various corrosive slurries in the smelting industry; various dilute acids in the sulfuric acid industry; Class sewage, etc. The pump is resistant to corrosion and wear, and has a wide range of applications.
Has the following characteristics:
1) Strong wear resistance: all wetted parts are made of steel-lined ultra-high molecular weight polyethylene (UHMW-PE). The wear resistance of ultra-high molecular weight polyethylene (UHMW-PE) ranks first among plastics, compared with nylon 66 ( PA66) and polytetrafluoroethylene (PTFE) are 4 times higher, 7-10 times the wear resistance of carbon steel and stainless steel.
2) Strong impact resistance: The impact strength of UHMWPE ranks first among general engineering plastics, which is 5 times that of (acrylonitrile/butadiene/styrene) copolymer (ABS), and can be minus 196 It remains stable at ℃, which is a feature that any other plastic does not have.
3) Excellent corrosion resistance: The pump can withstand various corrosive media (acids, alkalis, salts) and organic solvents within a certain temperature and concentration range. It is immersed in 80 organic solvents at 20°C and 90°C for 30 days. There is no abnormal appearance, and there is almost no change in other physical properties.
4) No noise: Ultra-high molecular weight polyethylene has a high impact energy absorption of plastics, and has good sound-absorbing properties, thereby greatly reducing the noise caused by liquid flow during the transportation process.
5) Element decomposition: The ultra-high molecular weight polyethylene (UHMW-PE) used in this pump has extremely stable chemical properties, so it is also suitable for use in the food industry.
6) Low coefficient of friction: The internal friction system of the pump is only 0.07-0.11, so it has self-lubricating properties. Under water lubrication conditions, its dynamic friction coefficient is half lower than PA66 and polyoxymethylene (POM). When working in sliding or rotating mode, it has better lubricity than steel and brass with lubricating oil.
7) Good adhesion resistance: Ultra-high molecular weight polyethylene (UHMW-PE) has excellent adhesion resistance, and its anti-adhesion ability is equivalent to that of PTFE, so it is also outstanding when transporting some higher viscosity media.

3. Application range of mortar pump
1) Sulfuric acid phosphate fertilizer industry: transportation of media such as dilute acid, mother liquor, sewage, sea water, fluorosilicic acid containing silica gel, and phosphoric acid slurry.
2) Non-ferrous metal smelting industry: It is especially suitable for various acids, corrosive ore slurry, and slurry (for filter press) electrolyte for lead, zinc, gold, silver, copper, manganese, cobalt, rare earth and other hydrometallurgical smelting. , Sewage and other media transportation.
3) Chemical industry and other enterprises: all kinds of sulphuric acid, hydrochloric acid, alkaline, oil clear liquid or slurry positions. Production of titanium dioxide, iron red powder, production of various dyes and pigments, non-metallic mineral processing and other industries.
4) Chlor-alkali industry: hydrochloric acid, liquid caustic soda, electrolyte, etc.
5) Water treatment industry: pure water, high-purity water, sewage (leather sewage, electroplating sewage, electronic sewage, papermaking sewage, textile sewage, food sewage, domestic sewage, pharmaceutical sewage, etc.).
6) Iron and steel enterprises: sulfuric acid and hydrochloric acid positions in the pickling system,
7) Wet desulfurization circulating pump: It can be used for alkaline, acidic and corrosive jobs at the same time.
8) Transportation of corrosive liquids and coal slurry in the coal industry and coal chemical industry; pumps for coal washing.
