Mortar pump is a pump that can adapt to various working conditions, such as conveying acidic or alkaline clear liquid or slurry; various corrosive ore pulps in the smelting industry; various dilute acids in the sulfuric acid industry; and various sewage in the environmental protection industry. This pump is not only corrosion-resistant but also wear-resistant, with a very wide range of applications. It has the following characteristics:
1) Excellent wear resistance:
All over-flow components are made of steel-lined ultra-high molecular weight polyethylene (UHMW-PE). The wear resistance of UHMW-PE ranks first among plastics, 4 times higher than nylon 66 (PA66) and PTFE, and 7-10 times higher than carbon steel and stainless steel.
2) Strong impact resistance:
The impact strength of ultra-high molecular weight polyethylene ranks first among general engineering plastics, 5 times higher than ABS, and can remain stable at -196℃, which is a characteristic that no other plastic possesses.
3) Excellent corrosion resistance:
This pump can resist various corrosive media (acids, alkalis, salts) and organic solvents within a certain temperature and concentration range. It was immersed in 80 kinds of organic solvents at 20℃ and 90℃ for 30 days. There was no abnormal phenomenon on the surface, and other physical properties hardly changed.
4) Noise-free:
The energy absorption of ultra-high molecular weight polyethylene is the highest among plastics, providing good noise reduction, thus minimizing the noise generated by liquid flow during transportation.
5) Safe and reliable, no toxin decomposition:
The chemical properties of ultra-high molecular weight polyethylene (UHMW-PE) used in this pump are extremely stable, making it also suitable for use in the food industry.
6) Low friction coefficient:
The internal friction coefficient of this 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 operating in sliding or rotating forms, its lubricity is better than that of steel and brass even with added lubricants.
7) Good anti-adhesion:
Ultra-high molecular weight polyethylene (UHMW-PE) has excellent anti-adhesion properties, comparable to PTFE, thus showing outstanding performance when conveying some high-viscosity media.
8) Application scope:
Conveying of masonry or plaster mortar in construction operations, pressure grouting operations in ports, docks, hydropower stations, etc., foundation treatment, soft ground reinforcement grouting, tunnel, subway, mine construction backfill grouting; anchor rod support.
