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.

Call us today for more information or to discuss your requirements. We look forward to the opportunity of serving you as a valued customer.

The impeller of slurry pump is an important part in the slurry pump. The slurry transportation depends on the centrifugal force generated by the high-speed rotation of the impeller. To the slurry pump accessories wear the fastest is also the impeller, so we want to replace the wear of the impeller, how to remove the impeller.

CNSME gives you an introduction.

The impeller of our slurry pump is usually buckled, which is opposite to the direction of rotation of the pump. From the direction of the pump inlet, the direction of rotation of the pump is counterclockwise rotation, so when the pump starts, the impeller will turn tighter. So if you want to remove the impeller, you need to jam the pump shaft with calipers, and then rotate according to the direction of rotation of the pump. Because the pump runs for a period of time, the impeller will be relatively tight, so when it is removed if it does not move, you can take a crowbar to knock a few times and try again.

Large pump will have impeller removal ring, then need to remove the removal ring, and then rotate the impeller.

How to paint the pump body of the slurry pump?

First, the selection method of slurry pump

The selection method of slurry pump is relatively simple, mainly according to the characteristics of the material to be transported and the transportation requirements. The following aspects need to be considered when selecting:

1. Material characteristics: mainly includes particle size, content, concentration, temperature, etc. Some materials with large particles or high concentration need to choose a large diameter slurry pump with large flow and high conveying pressure; Some materials with small particles or low concentration can choose a small diameter slurry pump with small flow and low conveying pressure.

2. Conveying distance and head: conveying distance and head determine the conveying capacity and working capacity of the pump, the farther the distance, the higher the head, the need to choose a large slurry pump with large power and large flow.

3. Output flow and transmission efficiency: the larger the output flow, the higher the transmission efficiency, but it also means that the energy consumption is higher. It needs to be selected according to the specific situation.

Two, the main parameters of the slurry pump

1. Flow rate: refers to the volume of liquid transported by the pump per unit time, the unit is m³/h or L/s, which is one of the important parameters of the slurry pump. According to the different conveying materials, the flow is also different, it is recommended to choose the flow that meets the actual needs.

2. Head: refers to the ability to overcome resistance to improve the liquid level height when transporting liquid, the unit is m or kPa. The larger the head, the more it can overcome the transmission resistance, but the more powerful the motor drive is required.

3. Speed: refers to the speed of the pump shaft rotation, the unit is r/min. In general, the higher the speed, the greater the flow of the pump, but the energy efficiency and service life will also be reduced.

4. Efficiency: refers to the proportion of the pump to convert the mechanical energy of the fluid. Efficient pumps reduce fuel consumption, noise and vibration when operating for long periods of time.

5. Sound level: also one of the important parameters. The lower the sound level, the smaller the noise, which is an important indicator of the safe and reliable operation of the slurry pump.

Third, the characteristics of different types of slurry pumps

1. Vertical slurry pump: suitable for conveying materials with higher concentration and larger particles, low noise, high pressure, and good wear resistance.

2. Horizontal slurry pump: suitable for conveying materials with low content and small particles, strengthening liquid flow power and increasing conveying capacity. At the same time, it is also widely used in seabed sediment extraction, artificial sand and pebble transportation and ordinary sand and pebble transportation.

3. High pressure slurry pump: suitable for conveying long distance, high head, high conveying pressure of large engineering occasions, is an indispensable important equipment in petroleum, chemical, mining, metallurgy and other industries.

Four, slurry pump maintenance and maintenance

1. Clean the liquid pipeline and the inside of the pump body to ensure that there is no caking, sediment and water accumulation.

2. Replace the liquid pipeline frequently to avoid long-term load transportation.

3. Regular maintenance and inspection of the rotor, bearing, seal, mechanical seal and other parts of the slurry pump, timely replacement of damaged parts.

4. Keep the pump body clean and check regularly to avoid damage and failure.

5. Prevent slurry pump overload and media backfilling, adjust pump output parameters in time to prevent performance degradation and failure.

The above is about the selection method of slurry pump, parameters, characteristics and maintenance and other aspects of the introduction, hope to be able to buy or use slurry pump users to provide a certain reference.
