3 What is The Difference of Submersible vs Vertical Slurry Pump?

3.1 Different Structure

Submersible slurry pumps integrate a specialized submersible motor in a coaxial, unified structure with the pumping body. Here, the motor rotor transmits rotational impetus directly to an internal impeller, forming a compact single unit smaller than vertical variants. This close coupling decreases noise and vibration while reducing losses through diminished transmission inefficiencies&#;providing superior flow and head relative to input energy.

Vertical slurry pumps commonly employ vertically-oriented motors separate from but connected to the body via drive shafts. This modular design eases servicing and part replacement to enhance maintainability. Meanwhile, TAIAN OCEAN PUMP&#;S technical experts discern application-tailored motor types for diverse conditions and media &#; selecting explosion-proof, high-temperature, or specialty motors where environments demand.

3.3 Different Operation Maintenance

Indeed, there are notable distinctions in the maintenance and upkeep of water slurry pumps and vertical slurry pumps in mining ore processing. These divergences primarily stem from their disparate structures and operational principles.

Let&#;s start with submersible slurry pumps. Typically situated at the bottom of the mine, these pumps are driven by a motor to convey the ore and mud mixture to the surface. Being submerged in water necessitates their design and construction to withstand water pressure and corrosion. Consequently, the maintenance and upkeep of submersible slurry pumps revolve around preserving their sealing capabilities and preventing corrosion. Regular checks on the sealing performance, cable connections, and other components of the submerged section are imperative to ensure the reliability and safety of this part. Additionally, due to the high solid particle content in mining ore processing, it becomes crucial to periodically clean the inlet, outlet, and internal slurry channels of the pump to avert particle blockages and sustain optimal pump efficiency. Our Ocean Pump R&D department has diligently engineered unique enhancements to the impeller, facilitating a wider flow path while guaranteeing a substantial flow output. This design enables smooth passage of large particles, effectively preventing clogging.

On the other hand, vertical slurry pumps are employed to pump out mud or slag from the ground and transport it to the surface. Typically installed at the top of the mine, these pumps are motor-driven to extract mud and transport it upwards. As they are situated on the ground, their design and structure are relatively uncomplicated and do not require resistance against water pressure or corrosion. Consequently, the maintenance and upkeep of vertical slurry pumps focus on sustaining their mechanical performance and preventing clogs. Regular inspections of bearings, replacement of worn parts, and clearing of blockages are essential maintenance measures.

To summarize, the maintenance and upkeep of submersible slurry pumps and vertical slurry pumps in mining ore processing differ due to their distinct structures and operational principles. Therefore, when utilizing and maintaining these two equipment types, appropriate measures must be taken in accordance with their characteristics and working environment to ensure smooth operation and prolonged service life.

3.4 Different Cost

When it comes to mining ore processing, there are distinct variations in costs between submersible slurry pumps and vertical slurry pumps. These disparities primarily revolve around acquisition expenses, installation fees, operational charges, and maintenance expenditures. Let&#;s take a closer look at the potential divergences in costs between the two types of pumps:

1 Purchase cost:

The purchase cost of submersible slurry pumps and vertical slurry pumps may vary depending on the specific model, specification and manufacturer. Generally, since the motor of a submersible slurry pump needs to be specially customized to provide stricter waterproof performance, the purchase cost of a vertical slurry pump may be slightly lower than a submersible slurry pump under the same power and output conditions. This is mainly because the structure of the vertical slurry pump is relatively simple and the manufacturing cost is relatively low. Therefore, during the purchase process, the choice needs to be weighed based on actual working conditions and budget.

2 Installation cost:

Submersible slurry pumps need to submerge into the medium to work, so submersible pipes, cable layout and related safety measures need to be considered during installation, which may increase the installation cost. Vertical slurry pumps are usually relatively simple to install and may not require diving and complex piping arrangements, so the installation cost may be lower.

3 Operating costs

Since the submersible slurry pump needs to work submerged in the medium, its energy consumption may be relatively high. It is usually necessary to overcome large water resistance and lifting height, so the energy consumption of submersible slurry pumps may be slightly higher compared to vertical slurry pumps.

4 Maintenance costs

   Normally, due to its special working environment, the submersible slurry pump requires the entire pump body to be submerged in the medium. Its internal components are susceptible to wear and corrosion, so it may require more frequent maintenance and repairs. Replacement parts, so its maintenance costs may be slightly higher than a vertical slurry pump.

Summary

Submersible and vertical slurry pumps play vital roles in handling slurry for mining projects. While they share similarities in terms of raw materials and functions, their differences lie in structure, efficiency, application, maintenance, and cost. When it comes to choosing between the two, it&#;s crucial to consider the specific requirements and conditions of your mining project. Consulting with slurry pump manufacturers or mining equipment experts can help determine the most suitable option for your application.

However, not all vertical slurry pumps are submerged underwater. It depends on the motor and the non-pump head compartments. It&#;s often used in conveying corrosive, coarse particles and high concentration slurry.

Submerged Slurry Pump

The Submerged Slurry Pump is a vertical single-stage single-suction cantilever centrifugal pump, and the impeller is a semi-open impeller. A mixing blade is arranged at the suction edge extension of the impeller. Its main selling point is the length of its pump shaft in the submerged part, reaching 800 to millimetres. It is mainly used in municipal engineering, paper mills, cement plants, printing and dyeing plants.

Submersible Slurry Pump

Last on the list is the submersible slurry pump. It is the coaxial integration of the pump and the motor. Its main selling point is there is no need to build complex fixtures and protective measures on the ground. It can be quickly submerged into the slurry and allow to do its job. Since a mechanical seal protects the motor, it prevents high-pressure water and impurities from entering the motor cavity. The submersible pump is most suitable for conveying slurry containing abrasive particles, such as sand, cinder and tailings.

How To Select the Right Slurry Pump

Selecting the correct type of slurry pump should be based on four factors: performance, material conveyed, sealing type and transmission mode. However, it can also depend on other factors, such as on-site working conditions and the acidity or alkalinity of the slurry.

It&#;s crucial to know about all these things to ensure that the chosen pump works along with its limits, providing superb performance and work satisfaction. There are four types of pumps for a reason&#;there are varied slurry types.

Conclusion

Selecting and operating a slurry pump can all vary based on various factors that play on-site. It&#;s a complex task due to how difficult it is to balance the pumps available in the market. However, try to consider the flow, pressure, viscosity, abrasiveness, particle size and particle type of the slurry you&#;re dealing with.
