Advantages of corrosion-resistant and wear-resistant mortar pumps

Thread Content

A corrosion- and wear-resistant mortar pump is a type of pump that can operate under various working conditions, such as transporting acidic or alkaline liquids or slurries； Various corrosive slurries in the metallurgical industry ； Various dilute acids in the sulfuric acid industry ； Various types of wastewater in the environmental protection industry, etc. This pump is resistant to corrosion and wear, making it suitable for a wide range of applications. It has the following advantages: 1. Excellent wear resistance: All components that are subject to flow are made of steel-reinforced ultra-high molecular weight polyethylene. Ultra-high molecular weight polyethylene boasts the best wear resistance among plastics; its wear resistance is 4 times higher than that of nylon 66 (PA66) and PTFE, and 7–10 times higher than that of carbon steel and stainless steel. 2. Excellent impact resistance: Ultra-high molecular weight polyethylene has the highest impact strength among common engineering plastics; it is 5 times stronger than acrylonitrile/butadiene/styrene copolymers (ABS), and it remains stable at -196°C, a property that no other plastic possesses. 3. Excellent corrosion resistance: This pump can withstand various corrosive media (acids, bases, salts) as well as organic solvents within certain temperature and concentration ranges; it was immersed in 80 types of organic solvents at 20°C and 90°C for 30 days. There are no abnormal appearances, and other physical properties have hardly changed either. 4. No noise: Ultra-high molecular weight polyethylene has the highest impact energy absorption among plastics, offering excellent sound-damping properties; this helps to minimize the noise generated by liquid flow during transportation. 5. Safe and reliable, with no toxin decomposition: The ultra-high molecular weight polyethylene used in this pump has extremely stable chemical properties, which makes it suitable for use in the food industry as well. 6. Low friction coefficient: The internal friction coefficient of this pump is only 0.07–0.11, giving it self-lubricating properties. Under water-lubricated conditions, its dynamic friction coefficient is half that of PA66 and polyoxymethylene (POM). When operating in a sliding or rotating manner, it exhibits even better lubricity than steel and brass when lubricated. 7. Good anti-adhesion properties: Ultra-high molecular weight polyethylene has excellent anti-adhesion properties, with an anti-adhesion capacity comparable to that of PTFE; therefore, it performs well when transporting media with high viscosity.
