Handling slurry in the mining and construction industries requires the selection of a hydraulic driven submersible slurry pump that can handle abrasive and dense materials. There are several key factors to consider in order to select the right pump size to meet your needs.

Determine Flow Requirements

To select the right size hydraulic submersible mud pump, you must first assess the required flow rate. Flow rate is measured in gallons per minute or cubic meters per hour and represents the total amount of mud that needs to be moved in a specific period of time. To accurately determine the flow rate requirements, the following points should be considered:

1. Production rate: Calculate the amount of mud that the operation generates or needs to handle in a fixed time.

2. System configuration: Consider the specific arrangement of the piping system, including pipe length, diameter, and components such as elbows or valves that may affect the flow rate.

3. Operation mode: Determine whether the pump is in continuous operation or intermittent operation, as this is related to the setting of the required flow rate.

4. Growth expectations: Leave room for possible production growth or operational adjustments that may require a larger flow rate in the future.

Taking all of the above factors into consideration, the minimum flow rate required for the hydraulic submersible mud pump can be calculated. It is usually recommended to select a pump slightly larger than the calculated value to ensure superior performance and to cope with unexpected increases in flow requirements.

Determine Head Requirements

When sizing a hydraulic driven submersible slurry pump, there are a variety of real-world head scenarios to consider. The head is the amount of pressure that the pump must overcome to move the mud. When calculating the total head, the following items need to be included:

1. Static head: This is the vertical distance from the pump suction to the highest discharge point, and this value is not affected by the mud flow rate.

2. Friction head: The resistance that mud encounters when flowing through pipes and fittings increases with the flow rate and the length of the pipe.

3. Velocity head: This represents the energy consumed to accelerate the mud from a static state to a specific flow rate.

4. Pressure head: If the system needs to transfer the mud at a specific pressure, this part of the pressure needs to be included in the total head calculation.

To accurately assess the head requirements, the density of the mud, the characteristics of the pipe, and the height changes of the system must also be considered. This requires close cooperation with an experienced engineer or pump expert to ensure that all of the above factors are fully considered. Hydraulically driven submersible mud pumps are designed for high-pressure working environments and are suitable for complex application scenarios such as deep pit drainage. To ensure that the equipment operates efficiently and prolongs its life, it is important to select a pump with the right head.

Consider The Size And Concentration Of Solid Particles

When handling slurries, the characteristics of the solid particles are critical to the sizing of a hydraulic driven submersible slurry pump. Here are the key considerations:

Particle size: The maximum particle size that the pump can handle is a critical parameter. Large particles require larger impeller passages and more robust construction to prevent clogging and damage.

Particle concentration: The proportion of solids in the slurry affects pump performance and wear rate. High concentrations require more powerful pumps and specially designed impellers and wear-resistant materials.

Particle shape and hardness: Abrasive, angular particles are more wear-prone to pump components than smooth, round particles, affecting material selection.

Settling rate: Some particles tend to settle quickly, which can cause pump or pipe clogging. Understanding this characteristic can help select the appropriate minimum flow rate pump to keep particles suspended.

Chemical composition: The chemical properties of the solids determine the pump material selection to ensure corrosion resistance and service life.

After a thorough analysis of the mud characteristics, a hydraulically driven submersible mud pump can be selected that meets both the flow and head requirements and the challenges of solid particles. Pump selection is a complex process that requires a comprehensive consideration of flow requirements, head requirements, and mud characteristics to ensure that the pump operates efficiently and reliably in a specific application.
