Heavy duty slurry pump metal lined War-man 8/6F-AH with 980r/min, 220Kw Electric Motor driven by belts and pulleys, CRz, shipped to Kazakhstan.

The main part of the sand gravel pump accessories is also called the overflow part. Including pump cover, impeller, volute, front guard, rear guard, etc.
This series of pumps are horizontal, single pump casing centrifugal pumps. The pump body and pump cover are clamped by special clamps, and the outlet direction of the pump can be in any position of 360 degrees, which is easy to install and use.
The shaft seals of the sand gravel pump include packing seals, impeller seals and mechanical seals.
Bearing assembly: The bearing assembly of the sand gravel pump adopts a cylindrical structure, which is convenient to adjust the gap between the impeller and the pump body, and can be removed as a whole during maintenance. Bearings are grease lubricated.
Transmission mode of sand gravel pump: there are mainly V-shaped V-belt transmission, elastic coupling transmission, gear reduction box transmission, hydraulic coupling transmission, frequency conversion drive device, thyristor speed regulation, etc.
The overall performance of the sand gravel pump: the material of the overflow parts is made of high-hardness wear-resistant alloy cast iron. The pump has a wide flow channel, good cavitation performance, high efficiency and wear resistance. Various speeds and variants are used to allow the pump to operate under design conditions. It has a long service life and high operating efficiency, and can meet many kinds of harsh conveying conditions

In industry and mining, "sludge" is very different from the cement-containing slurries we see on a daily basis. The resulting sludge may be highly viscous, abrasive, corrosive, or a combination of the three. Industrial sludge must be removed, transported and safely disposed of as these sludges can be toxic to the environment. Conventional sump pumps are not well suited for handling heavy sludge and will have a significantly shorter lifespan than pumps designed to pump sludge and slurries efficiently. Therefore, it is necessary to use professional MUD Pumps to pump these sludges.
Sludges, together with slurries, can be divided into two categories: those that contain solids that eventually settle, and those in which the solids remain in suspension.
Sludge containing permanently suspended particles is usually composed of very fine low impact particles that can be abrasive to the pump but mostly behave like water. Sludge containing particles that will eventually settle is a more unstable slurry that behaves differently than conventional liquids. When choosing a Sludge Pump, attention must be paid to flow rate and horsepower. Most slurry or sludge applications are made of coarse particles, so sludge pumps are designed for high impact and abrasion resistance.
At CNSME, we can help you identify the right type of sludge pump for your specific needs. We have an incredible engineering design team that comes up with concepts and develops excellent products. Call us today for more information or to discuss your requirements. We look forward to the opportunity of serving you as a valued customer.

If the Slurry Pump is found to be blocked during use, how to solve it is that many customers think that this is a relatively complicated problem. Once this blockage problem is not handled properly, it will easily cause damage to the equipment, thereby affecting the efficiency of use. Therefore, everyone should pay special attention to the clogging problem of the slurry pump. In fact, if you grasp the following points, you can easily solve the problem.


(1) The solid and hard deposits in the volute of the horizontal slurry pump make it silted up, and measures to remove the silt can be taken.


(2) If the axis of the shaft and the feeding box are different, the main reason is that the machining error is large and the installation is incorrect. Care should be taken to check that the installation is correct after installation. If the sealing water ring is seriously worn, it needs to be replaced with a new water ring. If the sealing water pipe is blocked, the sealing water cannot enter the middle of the packing, which will cause the packing to wear quickly and lead to leakage. The blocked water pipe should be dredged to keep the sealing water clean.


(3) If the impeller or the water inlet and outlet pipelines are blocked, the impeller or pipeline can be cleaned. If the impeller is seriously worn, it should be replaced. If the packing port leaks, the packing should be pressed tightly. If the conveying height is too high, the loss resistance in the pipe is too large, so reduce the conveying height or reduce the resistance.


The horizontal slurry pump should be regularly maintained during its use, including dredging. This can effectively avoid the problem of slurry pump blockage. If you encounter these problems in the later use of the slurry pump, you can follow the steps above. resolve.

Today we will understand the precautions of forth pump operation. CNSEM ®  will give you a brief introduction. Let's have a look together.

When the forh pump is running, it is necessary to check the operation of the bearing assembly regularly. If the bearing is heated during open operation, it is necessary to stop the pump and wait for the pump shaft to cool down before running again. If the temperature of the bearing is still too high, and the temperature continues to rise, it is necessary to disassemble the bearing assembly of the pump shaft to check what the reason is.

General bearing heating is mostly caused by too much grease, or by magazines in grease. The amount of bearing grease should be appropriate, but also need to ensure cleanliness, and grease should be added regularly.

The performance of the forth pump deteriorates with the increase of the wear interval of the impeller and the protection plate, and the efficiency decreases. Therefore, the impeller should be adjusted upward in time, so as to maintain a certain interval so that the forth pump can maintain high efficiency operation.

When the forth pump wear cannot meet the needs of the system, it should be replaced in time.
