Hydraulic driven submersible slurry pumps are mainly used to transport abrasives and high-concentration mud in many industries such as mining and construction. The continuous and efficient operation of a pump and its extended service life depend on regular maintenance and operation in accordance with regulations.

Maintenance And Care

Proper maintenance is critical to the longevity of a hydraulically driven submersible slurry pump. Regular maintenance prevents unexpected failures and ensures consistent pump performance.

Develop a regular inspection schedule. Inspections can help detect small problems before they become larger ones. Inspect pump components such as the impeller, casing, and seals for wear or damage. Pay special attention to the hydraulic motor, as it is the heart of the pump.

In terms of maintenance, regularly adjust or replace the packing gland to ensure a good seal and prevent leakage. The frequency of packing replacement will be affected by the type of packing, operating conditions, and mud properties.

Worn liners and plates should also be inspected regularly and replaced as needed. This allows the pump to operate properly and prevents damage to the casing.

After use, flush the pump with clean water to remove residual mud and prevent damage caused by mud solidification. This is especially important for pumps that are not used frequently.

After each inspection, keep a detailed record of repairs and replacement parts. This information is helpful in monitoring the condition of the pump, scheduling preventive maintenance, and identifying potential problems.

After each use, clean the pump thoroughly to remove any residual slurry or debris to prevent abrasive particles from accumulating and causing wear.

Lubricate all moving parts, such as bearings and seals, regularly with recommended lubricants to reduce friction, minimize wear and maintain optimal performance.

Operation Specifications

One way to extend the service life is to operate the hydraulic driven submersible slurry pump correctly. Improper operation will put extra stress on the pump, causing premature wear and possible failure.

When using, make sure the pump operates within the designed capacity range. Overload operation will cause excessive wear on components and may even burn out the motor. Similarly, operating at too low a capacity may also cause overheating and inefficient operation.

During operation, always pay attention to the temperature of the pump. Overheating can damage key components such as seals and bearings. Once an abnormal increase in temperature is found, the cause should be immediately identified, which may be insufficient lubrication, improper installation or a problem with the hydraulic system.

In addition, pay attention to the characteristics of the pumped mud. Different muds have different abrasiveness and density. Make sure that the pump is suitable for the type of mud being handled. Using a pump that is not suitable for highly abrasive or high-density muds will cause rapid wear and shorten the service life.

Before starting the pump, you must ensure that the pump is completely submerged and there are no cavitations. Even short-term dry running can cause serious damage to seals and other components.

Following these operating specifications can ensure the long-term and stable operation of the hydraulic submersible slurry pump.

Material And Accessories Selection

The performance and durability of hydraulic driven submersible slurry pumps are directly affected by the choice of materials and accessories. The right components can reduce replacement and ensure long-term stable operation of the pump.

The wetted parts of the pump need to be made of wear-resistant materials, such as high-chromium alloys. For highly abrasive slurries, tungsten carbide or ceramics can be considered.

Different impeller models and styles are selected for different usage scenarios. Closed impellers are efficient and suitable for general applications, while semi-open or open impellers are suitable for handling slurries containing solids or fibers.

The quality of seals and gaskets is related to the leak-proof and efficient maintenance of the pump. The material should match the pumping application.

Investing in accessories such as variable frequency drives can optimize the operation of the pump, reduce wear and energy consumption. At the same time, monitoring systems can provide real-time data to help with daily maintenance of the pump.

Proper maintenance, compliance with operating specifications, and careful selection of materials and accessories will help to extend the service life.
