Slurry pump is an overhung single-stage single-suction centrifugal pump designed for the transport of corrosive media containing fine particles. The pump is made of steel-lined ultra-high molecular weight polyethylene (UHMW-PE), which is the latest material. The most outstanding advantage of the generation of pumps for corrosion-resistant and wear-resistant engineering plastics is that it has the best wear resistance, impact resistance (especially low temperature impact resistance), creep resistance (resistance to environmental stress) in all plastics. Cracking) and excellent corrosion resistance.
The slurry pump is a pump that can adapt to various working conditions, such as conveying acid, alkaline liquid or slurry; various corrosive pulps in the smelting industry; various types of dilute acid in the sulfuric acid industry; various types of sewage in the environmental protection industry, etc. . The pump is both corrosion and wear resistant and has a wide range of applications.
Has the following characteristics:
1) Strong wear resistance:
The flow-through parts are all 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) is 4 times higher than 7-10 times of carbon steel and stainless steel.
2) Strong impact resistance:
Ultra-high molecular weight polyethylene has the highest impact strength of general engineering plastics, five times that of (acrylonitrile/butadiene/styrene) copolymer (ABS), and can be stable at minus 196 ° C. This is the other. Any characteristic that plastics do not have.
3) Excellent corrosion resistance:
The pump is resistant to various corrosive media (acids, alkalis, salts) and organic solvents at a temperature and concentration range, and is immersed in 80 organic solvents at 20 ° C and 90 ° C for 30 days. There is no abnormality in appearance, and other physical properties are almost unchanged.
4) No noise:
The impact energy absorption of ultra high molecular weight polyethylene is the highest value in plastics, and the sound absorbing property is good, so that the noise generated by liquid flow is minimized during transportation.
5) Safe and reliable, no toxin decomposition:
The ultra-high molecular weight polyethylene (UHMW-PE) used in this pump is extremely stable and therefore suitable for use in the food industry.
6) Low friction coefficient:
The internal friction coefficient of the pump is only 0.07-0.11, so it has self-lubricating properties. Under water lubrication conditions, the dynamic friction coefficient is lower than that of PA66 and polyoxymethylene (POM). When working in sliding or rotating form, it is more lubricious than steel and brass when lubricated.
7) Good anti-sticking:
Ultra High Molecular Weight Polyethylene (UHMW-PE) is extremely resistant to sticking and has the same adhesion resistance as PTFE, so it is also outstanding when transporting some highly viscous media.
8) Scope of application:
Masonry or plastering mortar transportation in construction operations, pressure grouting operations such as ports, docks, hydropower stations, foundation treatment, soft foundation reinforcement grouting, tunnel, subway, mine construction backfill grouting; bolt support.
