This guide will tell you how to evaluate the slurry pump suppliers in China, all the important factors you should consider before you decide to purchase, and why you should choose CNSME as your supplier.

Slurry pumps can serve important functions in the paper industry, particularly in applications involving abrasive wastewater, sand and grit removal, suitable sludge transfer, and mineral-based slurry handling.

However, the selection of a slurry pump should never be based solely on the fact that a process medium contains solids. Particle size, solids concentration, fiber characteristics, viscosity, abrasiveness, and chemical compatibility all influence pump performance and service life.

By matching the pump structure, wet-end materials, and sealing arrangement to the actual process conditions, paper mills can improve pumping reliability, reduce wear-related maintenance, and achieve more efficient solids handling.

Flue Gas Desulfurization (FGD) pumps are an essential component in the process of removing sulfur dioxide from the flue gas emissions of power plants.

Learn how to choose a reliable Warman replacement slurry pump manufacturer in China. Discover key factors including dimensional compatibility, material quality, manufacturing capabilities and after-sales support.

This guide will show you how to compare slurry pump manufacturers before making a purchasing decision.

This article outlines several key factors you should discuss with the manufacturer before finalizing the design for a custom slurry pump.

This guide covers everything you need to check before purchasing a heavy-duty slurry pump—from the metal materials used for internal components to how well the pump integrates with your existing system.

A slurry pump performance test is used to verify a pump's operating characteristics under different flow conditions, including flow rate, head, speed, power, and efficiency.

This article uses an actual 65QV-SP vertical sump slurry pump performance test report from Shijiazhuang Minerals Equipment Co., Ltd. as an example. The test was conducted with clean water, and multiple operating points were recorded to evaluate the pump's hydraulic performance and generate its performance curves.

The article explains what parameters are measured during a slurry pump test, how to understand flow, head, efficiency, and performance curves, and how a performance test report can be used to verify pump performance. For customers who require performance verification, clean-water testing can be arranged according to their requirements, with a corresponding performance test report provided after testing.

CNSME will be closed from September 25–27, 2026 for the Mid-Autumn Festival holiday and will resume normal operations on September 28. 🌕

In slurry transportation systems, pump head is one of the key parameters used to determine the appropriate slurry pump.

Many people simply understand pump head as “how high a pump can lift slurry,” but the actual situation is more complex. Pump head represents the energy gained by a unit weight of liquid as it passes through the pump. In an actual conveying system, the head that the pump needs to provide is related to the liquid levels, pipeline losses, pressure conditions, and operating conditions of the system.

The type ‘SF’ Froth Pump is a vertical pump complete with hopper which utilises casings and liners from the Type ‘SH’ pumps.

The 2QV-AF Vertical Froth Pump is an essential solution for flotation processes, offering reliable performance and excellent adaptability for handling high-froth slurry.

The 6SV-AF vertical froth pump impeller is a key hydraulic component designed for the 6SV-AF vertical froth pump. Identified by Basic Part No. 127 and Basic Part Description IMPELLER-5VOG, this impeller features a five-vane configuration.

100RV-SP is a vertical slurry pump, designed for conveying high concentration, high abrasive slurry, widely used in mining, metallurgy, power and other industries

The CNSME 300TV-SP Vertical Slurry Pump is designed for slurry handling in mining, mineral processing, and other industries involving abrasive solid-liquid mixtures. Its vertical structure allows the pump to operate with the pumping end submerged in the slurry, making it suitable for sump drainage and slurry transfer applications.

Designed for heavy-duty service, the 300TV-SP combines a robust pump structure with replaceable wear components to support reliable operation in abrasive environments. It is a practical choice for industrial sites requiring efficient slurry transfer from collection pits, sumps, and process tanks.

The 6/4 AH slurry pump, the ultimate solution for all your solids handling and pumping needs. This innovative pump is designed to effectively handle abrasive and corrosive slurries, making it ideal for applications in mining, mineral processing, power generation and other industries. With its advanced technology and superior performance, the 6/4 AH slurry pump provides a reliable and cost-effective solution to your toughest pumping challenges.

The DAM073 stuffing box is a spare part for the 6/4D-AH slurry pump. It is designed for the stuffing box assembly in the pump's shaft sealing area. CNSME supplies slurry pump spare parts for different pump models, helping customers identify the correct components by pump model and part number. Contact us to confirm compatibility and material requirements before ordering.

The stuffing box is installed at the shaft seal section of the slurry pump, located at the connection between the pump body and the pump shaft. Its primary function is to prevent slurry leakage along the shaft, provide effective sealing protection, and ensure stable and reliable pump operation under abrasive slurry conditions.

As a critical sealing component of the 3/2C-AH slurry pump, the stuffing box helps protect the pump shaft and pump casing, improves sealing efficiency, and significantly extends the service life of the pump.

Stuffing box is mainly used for gland seal slurry pump, but may also play an auxiliary role in some special sealing program. Its role is to fix the packing, provide sealing space, and allow the right amount of lubrication and cooling to ensure that the pump shaft long-term stable operation.

The CNSME 400ST-L Light Duty Slurry Pump belongs to the L range of slurry pumps, developed for industrial slurry transportation duties. Its large suction and discharge connections support high-volume flow requirements, while the performance curve helps engineers evaluate suitable combinations of flow rate, head, and rotational speed.

The 400ST-L features a closed metal impeller with an 825 mm diameter and the basic impeller code STL10147. The supplied technical chart specifies metal materials for both the impeller and liner.

The L range offers metal and elastomer material options across its listed models, except model 20A-L. The appropriate configuration depends on the slurry characteristics, operating conditions, and required wear resistance.

For reliable operation, the pump should be selected according to the required flow rate, total dynamic head, slurry properties, and system conditions.

The Slurry Pump Base is typically located at the bottom or as part of the supporting structure, fixed to the pump’s frame or base. It is usually connected to key components such as the motor, pump casing, and bearings.
