Electric submersible slurry pumps are designed to handle abrasive and high-density liquids containing solid particles and are widely used in many industries such as mining, resource development and wastewater treatment. Correct installation, regular maintenance and compliance with standardized operating procedures can not only effectively extend the service life of the pump, but also ensure its stable operation, thereby reducing unnecessary cost expenditures.This exhaustive manual will direct you through the vital parts of dealing with your sub slurry pump actually.

Pre-installation inspection

Before installing the electric submersible slurry pump, you have to check it carefully to see if all the parts are good and not damaged. First disassemble the pump to see if there are any signs of bumps during transportation. Especially the pump housing, impeller, motor housing and wires, make sure they are flat and smooth, without cracks, potholes or worn places.

Then, check the list one by one to see if the pump, wires, control panel and those small parts are complete. Also check whether the voltage, frequency and strength of the pump meet our requirements.

Then check whether the impeller rotates smoothly and there is nothing blocking it in the pump housing. If the pump has a seal, check whether the oil is enough, and add some if it is not. The wires should also be carefully checked to see if there are any broken places, otherwise there should be leakage.

Finally, compare the nameplate information on the pump body with the specifications required when ordering, and they must be exactly the same. In this way, there will be no problems with installation or use due to the wrong model. If this step is done well, the subsequent installation and use will be much easier.

Installation

Your electric submersible slurry pump's performance and longevity depend on how well it is installed.When choosing a location to mount the pump, consider the following key factors: ease of maintenance, distance from the power source, and immersion requirements of the pump.

When mounting the pump, ensure that the location is stable and level. Also, keep the sump or pit clean and clear of anything that could interfere with the pump's operation. To facilitate removal and reinstallation of the pump, it is recommended to use strong lifting components such as chains or chain rings.

Connect the discharge line to the pump outlet and use appropriate fittings to ensure that the connection is tightly sealed to prevent leakage. When the pump is not in operation, it is recommended to install a check valve on the discharge line to prevent fluid backflow. If the application needs or local regulations require additional installation of appropriate valves or monitoring equipment.

During operation of the pump, always secure the power cord to prevent it from entanglement or damage.Attach it to the discharge pipe at regular intervals with cable ties or clamps, leaving enough slack to accommodate pump movement.

When lowering the pump to the intended location, do not use the power cord to support the weight of the pump. Use a lifting cable or chain that is specifically connected to the pump's lifting lugs. This allows the pump to be placed completely and smoothly to the correct depth.

After lowering, the pump needs to be connected to the control panel and power supply. When performing this step, all electrical specifications and safety guidelines must be strictly followed. Before officially putting the pump into use, ask a professional electrician to check the direction of rotation of the pump and complete the final electrical connection work so that the pump can operate normally and safely and reliably.

Maintenance And Repair

Regular maintenance is an effective way to improve the efficiency and extend the life of electric submersible slurry pumps. It is important to develop a suitable maintenance plan based on the manufacturer's guidance and the actual operating environment of the application.

During daily inspections, carefully observe the pump for signs of wear, leaks or unusual sounds. Record key data such as flow, pressure and power consumption to monitor the performance of the pump at any time. Any significant deviation from normal values may be a sign that maintenance or repair is needed.

To prevent solids or debris accumulation from reducing pump speed, the pump should be cleaned regularly. The pump body can be directly flushed with clean water or, according to the manufacturer's recommendations, a dedicated cleaning product can be used to clean the pump.

Inspect and replace worn parts such as wear plates, seals and impellers according to the manufacturer's guidelines. Due to the working nature of slurry pumping, these parts are susceptible to erosion and wear and need to be replaced regularly to ensure optimal performance of the pump.

It is also important to maintain electrical components, including motor windings, control panels and power cables. Be alert to overheating, disconnected connections or damaged insulation. If any problems are found, they should be resolved promptly to avoid further damage.

When replacing parts, always use genuine parts and follow the manufacturer's repair guidelines when necessary. For more complex maintenance or overhaul work, consider sending the pump to a certified service center or contact the manufacturer's technical support team.

Proper startup procedures are essential to ensure safe and efficient operation of electric submersible slurry pumps. When starting the pump for the first time or restarting it after a long period of inactivity, follow these steps to ensure optimal performance and reduce the risk of damage:

First, confirm that the pump is properly installed and all connections are secure. Check that the power supply meets the voltage and frequency requirements of the pump. Make sure the pump body is completely covered by the pumped medium.

Assuming your pump is outfitted with a seal cooling framework, make sure that it is appropriately loaded up with the suggested coolant.For pumps that have a full motor cavity, check the oil level and add the appropriate amount of oil if necessary.

Before starting the pump, manually rotate the impeller to ensure that it can rotate freely and without any obstruction. This can usually be achieved by inserting a screwdriver or other appropriate tool from the suction port and contacting the impeller.

When starting the pump, pay close attention to any unusual noises, vibrations, or other signs of potential problems. You can confirm that the pump is rotating in the correct direction by observing the discharge flow or using other methods recommended by the manufacturer.

After initially confirming that the pump is performing properly, let it run for a short period of time, usually a few minutes. During this time, check the seals and connections for leaks. Also, verify that the pump can achieve the expected pressure and flow standards.

If the pump performs normally during the initial operation stage, you can gradually increase its load until it reaches normal operating conditions. During this process, continue to pay attention to the relevant indicators on the control panel and the overall performance of the pump.
