The CNSME WRT impeller design (Wear Reduction Technology) offers improved hydraulic efficiency, reduced wear, and longer service life for slurry pumps. Fully compatible with Warman® WRT® systems, it provides high performance and cost-effective solutions for mining, mineral processing, power plant desulfurization, and other abrasive slurry applications.

Gravel pumps play a vital role in the industrial sector, enabling them to handle abrasive materials in harsh environments such as mining, dredging, and construction.

Vertical froth pumps provide an effective solution for handling high-viscosity aerated slurries across various industries. Their advanced impeller and tank systems ensure reliable performance even in applications where traditional pumps are inadequate.

Our team from Hebei, China is proud to be here in Tashkent, connecting with mining professionals worldwide.

When a slurry pump shows insufficient pressure, it can be caused by issues such as gas accumulation inside the pump, damaged inlet valves, high slurry concentration, or impeller wear. Regular inspection and timely maintenance can effectively prevent these problems. The article introduces each cause in detail and offers practical troubleshooting methods, emphasizing the importance of professional maintenance to keep the slurry pump running efficiently and reliably.

CNSME Pump will participate in MiningMetals Uzbekistan 2025 from October 28–30 in Tashkent, Uzbekistan. As a professional slurry pump manufacturer with over 20 years of experience, CNSME will present its brand, technology, and customized solutions to global mining and metallurgy professionals at Booth B78.

CNSME has a rich product line of pumps that can be tailored to customer needs and uses high-quality materials such as high chromium alloy to ensure the durability of the products.

A well-designed slurry pump can move materials efficiently, making mining operations run more smoothly.

Warman pumps are widely recognized for their excellent performance and durability in handling abrasive and corrosive slurries. However, even the most robust slurry pumps require regular maintenance and replacement of spare parts to maintain efficiency and extend service life.

Heavy-duty slurry pumps have become indispensable tools for industries handling abrasive, fluid-containing solids. They are widely used in mining, power generation, dredging, wastewater treatment and chemical processing.

CNSME®8/6F-AH horizontal slurry pump is a high-efficiency, wear-resistant, corrosion-resistant single-stage single-suction, cantilever, horizontal centrifugal slurry pump, which widely used in mining, electric power, metallurgy, coal, chemical industry and other industries. It is suitable for pumping highly abrasive, high-concentration slurry or low-concentration high head slurry. It can be used in multiple stages in series under the pump's max. allowable working pressure range.

CNSME®8/6E-AH horizontal slurry pump is a high-efficiency, wear-resistant, corrosion-resistant single-stage single-suction, cantilever, horizontal centrifugal slurry pump, which widely used in mining, electric power, metallurgy, coal, chemical industry and other industries. It is suitable for pumping highly abrasive, high-concentration slurry or low-concentration high head slurry.

The SV heavy duty cantilever sump pump is designed for applications requiring greater reliability and durability than conventional vertical process pumps can offer.

The 100RV-SP vertical slurry pump is designed for pumping abrasive and corrosive liquids and slurries, and can be submerged in sump or deep pits. It is suitable for applications that require reliability and durability higher than traditional vertical process pumps. It is mainly used for pumping highly abrasive, highly corrosive, highly concentrated slurries containing suspended solid particles.

Spare Parts for Vertical Slurry Pumps
Metal casing can be used for sp vertical slurry pump
Material: Metal
Casing is an important wear part of the vertical slurry pumps. It forms a slurry pump chamber where the slurry would flow through.

Spare part door clamp ring for gravel pump is mainly used to connect and fix various parts of the pump to ensure sealing and stability. It plays a key role in the operation of gravel pumps, especially under high abrasion and vibration conditions.

Slurry Pump Packing is a critical sealing component installed inside the stuffing box of slurry pumps. It functions as a gland seal to effectively prevent leakage of slurry, water, or chemicals between the moving parts of the pump shaft and casing.

Froth Pump SF/50QV，froth pump,froth pump manufacturer designed and manufactured using the finest quality raw materials and the latest technology in accordance with the industry norms and standards.

Froth pumps, also known as foam pumps, are a kind of vertical tank slurry pumps. They are used for flotation process where froth is innevitable.

The 4/3D-AH and 4/3D-AHR slurry pumps are based on the same 4/3D pump platform but use different wet-end configurations for different slurry conditions. The 4/3D-AH is equipped with metal liners and a metal impeller, providing excellent wear resistance for highly abrasive slurry applications in mining, mineral processing, coal and other industries. It uses a D3147 impeller with a 245 mm diameter, a maximum speed of 2750 rpm and a maximum passage size of 36 mm. The 4/3D-AHR features polymer liners and a polymer impeller, using a D3147R impeller with a 215 mm diameter, a maximum speed of 1950 rpm and a maximum passage size of 28 mm. The two configurations allow users to select suitable wet-end materials according to slurry concentration, particle characteristics, abrasiveness and operating conditions.

CNSME 2/1.5B-AH horizontal slurry pump, dimension interchangeable with AH series pumps, B frame 15KW, A05 alloy wet parts, ISO9001 CE EAC certified. Send your slurry data for free quotation & performance curve.

1.5/1B-AH slurry pump is cantilever centrifugal slurry pump, which is suitable for transporting abrasive or corrosive slurry,which is widely used in mineral processing, metallurgy, petroleum, chemical industry, coal mining and other industries.

1.5/1B-AH Slurry Pump is end-suction, split-case, centrifugal slurry pumps have set the world standard for heavy duty abrasive pumping applications. With large shaft diameters, heavy duty bearing assemblies and robust slurry pumping capacity, Application customization comes standard with this line by applying a wide variety of metallic and elastomeric parts options, an assortment of seal arrangements, and a standard impeller adjustment mechanism incorporated into every base assembly.

The 3/2 AH slurry pump, manufactured by CNSME PUMP, adopts a metal closed impeller with 5 vanes and an impeller diameter of 214 mm.
