During operation, there are four types of common failures of slurry pumps​: corrosion and abrasion, mechanical failure, performance failure and shaft sealing failure. These four types of failures often affect each other.

The operation of mechanical seals directly affects the normal operation of the slurry pump.

The Slurry Pump is a Industrial Pump that conveys a mixture of solids and water.

At present, the lubrication methods of slurry pump bearings are grease lubrication and thin oil lubrication.

In the applications of slurry pumps, frequency conversion operation is sometimes required.

Concept of pump: all machines that are used to lift liquid, transport liquid, and increase the pressure of liquid can be called “PUMP”

There are three main types of shaft seals for slurry pumps: packing seal, expeller seal, and mechanical seal.

At CNSME, you'll find a wide inventory of pumps and parts that are 100% interchangeable with the world's most recognized slurry pump brand.

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

Heavy Duty Slurry Pumps SH/250ST (12/10ST-AH) ready to be shipped to our customer from outside China.

The seal of the Expeller of the slurry pump is sealed by the hydrodynamic action, which belongs to the non-contact seal. The air or clean water generates pressure under the rotating action of the Expeller, and forms an air slurry or water slurry balance with the slurry at the outer edge of the Expeller, thus resisting the leakage of the liquid at the outlet of the main impeller.

The CNSME 750V-MCU series impeller is purpose-built for large vertical slurry pumps. Featuring an advanced open multi-vane design and premium wear-resistant materials, it excels in handling high-density, coarse particle, highly abrasive slurries. Ideal for mining, power plants, metallurgy, and other heavy-duty industries, it delivers maximum efficiency with reduced maintenance costs.

The C2058 impeller is a high-performance, 6-vane closed impeller designed for the 3/2C-AH slurry pump. Engineered for excellent hydraulic efficiency and wear resistance, it is ideal for transporting abrasive and corrosive slurries in demanding applications such as mining, mineral processing, and chemical slurry handling.

The TC25191A05-8VCG is a torque flow (vortex type) impeller designed for the 250TC vertical non-clog vortex pump. Its open, recessed impeller structure allows fluid to pass through without direct contact with the vanes, effectively handling large solids, fibrous materials, and abrasive slurries with minimal clogging.

The CNSME 6/4D-G gravel pump impeller is engineered for high efficiency and wear resistance. Made from high-chrome alloy, it is specially designed to handle large particles and highly abrasive slurries, making it ideal for dredging, sand mining, and sever

The SP25206A05-5V is a double-sided (dual suction) impeller designed for the 250TV-SP vertical sump slurry pump. This impeller features a high-efficiency open design that allows for the handling of high volumes of abrasive and corrosive slurries.

The SP10191A05 impeller is a torque flow (vortex type) impeller specifically designed for the 100RV-SP vertical sump slurry pump. Its non-clogging design is ideal for pumping slurries with large solids, fibrous materials, or corrosive particles.

Impeller is the most important wet-end spare part of a slurry pump. Centrifugal pumps need impellers to produce the centrifugal force which transfers the slurries.

CNSME's slurry pump spare parts such as slurry pump impellers and Warman pump impellers have a variety of design structures to meet customer needs.

GMC20145EL1 is a four-vane closed impeller designed for the 200MCR mill circuit underflow pump. Made of A05 high chrome alloy, it provides excellent wear and corrosion resistance, ideal for handling highly abrasive mill discharge and slurry applications.

GAM14747RE1 is a high chrome wear-resistant impeller designed for the 16/14TU-AH heavy-duty slurry pump. It is suitable for highly abrasive applications such as mining, mineral processing, and tailings transport. This impeller delivers excellent wear resistance, stable hydraulic performance, and extended service life. Fully interchangeable with major international brands, it ensures reliable installation and efficient slurry handling in high-density and high-impact working conditions.

CNSME SHF (AHF) Froth Pumps are heavy duty horizontal pumps designed to handle difficult tenacious froth.
Froth handling can be quite frustrating in some applications, and the froth inducer blade impeller solves this problem. Another benefit of a froth impeller design and oversized pump inlet is that it raises the solids concentration limits that a common centrifugal pump can handle.
This froth impeller has 4 open vanes
