Another batch of pumps went to their new site. This week, we loaded over 20 complete sets of
heavy duty AH series slurry pumps
along with elec. motors and accessories, and these pumps are going to be shipped to our customer in one of the Russian-speaking countries.


All these slurry pumps are expeller sealed. And in fact, expeller (ring) seal becomes our standard method of shaft sealing. Most customers ask for the reasons. That's because Expellers can be applied in virtually all slurries regardless of solid concentration. Slurry pumps manufactured by CNSME, are suited for expeller seals due to the abrasive nature of the slurry being pumped, and the typical lack of readily available, clean and pressurized gland seal water. Clean water can often be hard to come by in mining mills and mineral processing environments, and packing and sleeves may fail quickly when abrasive particles in the seal water or slurry itself enter the stuffing box. But this doesn't mean we will not offer other shaft sealing options. Gland/Packing seal and mechanical seal are also available for our slurry pumps, if the customers prefer to use these two sealing methods.

The Slurry Pump is a
Industrial Pump
that conveys a mixture of solids and water. Therefore, the medium will be abrasive to the flowing parts of the slurry pump. Therefore, the slurry pump flowing parts need to be made of wear-resistant materials.


The commonly used metal materials for
slurry pumps
are divided into cast iron, ductile iron, high chromium cast iron, stainless steel and so on. High chromium cast iron is the third generation of wear-resistant material developed after ordinary white cast iron and nickel hard cast iron. Due to the characteristics of the structure of high chromium cast iron, it has much higher toughness, higher temperature strength, heat resistance and wear resistance than ordinary cast iron. High chromium cast iron has been praised as the best anti-abrasive material in the contemporary era, and it has been widely used day by day.


China's national standard for wear-resistant white cast iron (GB/T8263) stipulates the grade, composition, hardness, heat treatment process and usage characteristics of high chromium white cast iron.


The executive standard for high chromium cast iron in the United States is ASTMA532M, the United Kingdom BS4844, Germany DIN1695, and France NFA32401. Russia developed 12-15% Cr, 3-5.5% Mn and 200mm wall thickness ball mill liners in the former Soviet Union, and now implements the ҐOCT7769 standard.


The main materials used for the flowing parts of slurry pumps at home and abroad are stainless steel, high chromium cast iron and nickel hard cast iron. High chromium cast iron is an ideal candidate material for the flowing parts of slurry pumps. Through the adjustment or selection of carbon and chromium content levels, the best use effects of flowing parts under different industrial and mining conditions can be obtained.


High chromium cast iron is the abbreviation of high chromium white anti-wear cast iron. It is an anti-wear material with excellent performance and special attention; it has much higher wear resistance than alloy steel and much higher toughness and strength than general white cast iron. At the same time, it also has good resistance to high temperature and corrosion, coupled with convenient production and moderate cost, and is known as one of the best anti-abrasive materials in the modern time.


Now A series of high chromium cast iron wear-resistant materials are the commonly used:


The slurry pumps made of A05 (Cr26) material are the most widely used in the mining industry. The micro-structure of the high chromium alloy A05 shows that it consists of hard eutectic chromium carbides in a fully hardened marten-site matrix. In slurry pump applications where both abrasive and corrosive but abrasion dominates, the performance of this material is significantly better than the other white cast irons.


Although the wetted parts made of A07 (Cr15Mo3) material have higher wear resistance, better hardness and longer service life than A05, their cost is twice of that of A05, so the cost performance is lower and the scope of use is smaller.


A49 (Cr30) is essentially a high chromium low carbon white cast iron. The micro-structure is hypo-eutectic and consists of eutectic chromium carbides in an austenite/martensite matrix. The carbon content of high chromium A49 is lower than that of high chromium A05. There is more chromium in the matrix. In a weakly acidic environment, high chromium A49 has higher corrosion resistance than high chromium A05.


For now, the above mentioned are the metal materials commonly used in our slurry pumps. According to the particularity of the transported medium, Slurry pump manufactures will choose the most suitable material for you.

When it comes to slurry pumps, China has become a leading global supplier. However, there is a common


misconception that products manufactured in China cannot be of good quality when offered at a lower


price. This article aims to debunk this myth by focusing on one prominent Chinese slurry pump supplier,


CNSME, which not only guarantees high-quality products but also ensures exceptional after-sales service.



With over 30 years of experience in manufacturing and supplying slurry pumps, CNSME has established


itself as a reliable and trustworthy player in the industry. This Chinese company combines its extensive


expertise with advanced technologies to produce slurry pumps that not only meet international quality


standards but also outperform expectations. By strictly adhering to stringent quality control measures,


CNSME ensures its products are durable, reliable, and capable of handling a wide range of demanding


applications.


One of the main reasons China slurry pumps are often perceived as having lower quality is due to their


competitive prices. Some people wrongly assume that lower prices equate to compromising on quality.


However, CNSME manages to offer affordable prices without compromising on the quality of their slurry


pumps. By leveraging cost-effective manufacturing processes, economies of scale, and efficient supply


chain management, CNSME is able to provide customers with cost-competitive solutions, making their


slurry pumps highly desirable in the market.


In addition to their high-quality products and competitive pricing, CNSME also prides itself on offering


excellent after-sales service. The company understands that customer satisfaction goes beyond the initial


purchase. Therefore, CNSME provides comprehensive after-sales support to ensure their customers'


ongoing success. This includes timely delivery, installation guidance, technical assistance, and prompt


response to inquiries or concerns. CNSME believes that maintaining a strong relationship with their


customers is crucial, and their dedication to exceptional after-sales service reflects their commitment to


customer satisfaction.


In conclusion, the notion that China slurry pumps cannot be of good quality, offered at a cheap price,


and provide excellent after-sales service is simply a misconception. CNSME, a reputable Chinese slurry


pump supplier, has defied this stereotype by consistently delivering high-quality products, competitive


pricing, and reliable after-sales support for over three decades. When considering slurry pumps, don't


overlook the offerings from CNSME, as they continue to set the standard for quality, affordability, and


customer service in the industry.
