1. What is Submersible Sand Pumps

Submersible Sand Pump, also known as the submerged suction pump or submersible slurry pump, is a product crafted and engineered by Ocean Pump company. Initially, our submersible sand pumps were primarily employed in challenging environments such as coal slag delivery and tailing handling. The essential components of these pumps, including the impeller, share the same structural prototype as those found in horizontal slurry pumps.

The advantages of our submersible sand pumps encompass their ease of operation, self-mixing capabilities, high resistance to abrasion, energy efficiency, environmental friendliness, low noise levels, and a low failure rate. In recent years, Ocean Pump Co., Ltd. has introduced innovative variations of submersible sand pumps to cater to diverse working conditions. These innovations include high-pressure water jet submersible sand pumps, large-particle submersible sand pumps, submersible sand pumps with side cutters, hydraulic-driven submersible sand pumps with side cutters, stainless steel submersible slurry pumps, and deep-well submersible sand pumps.

Presently, submersible sand pumps find extensive applications in sand extraction, landfilling, river dredging, tailings processing, and various other projects. These pumps have demonstrated their reliability and efficiency in meeting construction requirements across a range of working conditions.

2. Advantages of Submersible Sand Pumps

Submersible sand pumps offer efficient and reliable solutions for sand and solids handling. Their ability to handle abrasive materials, versatility in applications, submersible design, portability, low maintenance requirements, and energy efficiency make them advantageous choices in various industries and environments.
Submersible sand pumps offer several advantages in various applications where the pumping of sand and other solids is required.

1. Efficient Sand Handling: Submersible sand pumps are specifically designed to handle abrasive materials like sand, gravel, and sediment effectively. They are equipped with robust impellers and wear-resistant materials that can withstand the erosive nature of sand particles, ensuring efficient pumping without clogging or excessive wear.

2 Robust structure. The prototype of the submersible sand pumps impeller is something like  the horizontal slurry pump, it features strong wear resistance material with the relatively narrow flow passage.
Submersible sand pumps are typically compact and portable, making them easy to transport and deploy in different locations. They can be mounted on floats or skids for convenient movement and positioning. This portability enables efficient sand pumping in various areas, including remote or hard-to-reach locations.

3.Submersible Design: The submersible nature of these pumps allows them to be fully submerged in the fluid being pumped. This design eliminates the need for priming and provides more efficient pumping by reducing suction head requirements. Submersible sand pumps can be easily lowered into the fluid without the need for additional equipment or infrastructure.
4 Large particle flow design. The motor, impeller and the stirring impeller are coaxial and belong to the hard connection. Therefore, once overload operation occurs, the possibility of motor damage will increase. As a result, Ocean Pump company had tackled this problem by designing large-particle-flow submersible sand pumps and hydraulic supporting system through scientific and technological research.
4.Energy Efficient: These pumps are designed to be energy efficient, reducing operational costs. They are equipped with efficient motors and hydraulic systems that maximize the transfer of power to the sand pumping process, minimizing energy wastage.
5.Low Maintenance Requirements: Submersible sand pumps are designed for durability and require minimal maintenance. They are constructed with high-quality materials and components that can withstand harsh operating conditions. Additionally, the absence of external seals and bearings in the submerged design reduces the risk of mechanical failure and simplifies maintenance procedures.

Submersible sand pumps offer efficient and reliable solutions for sand and solids handling. Their ability to handle abrasive materials, versatility in applications, submersible design, portability, low maintenance requirements, and energy efficiency make them advantageous choices in various industries and environments.

3. Two different types of Submersible Sand Pumps

For the selection of submersible sand pumps, it is necessary to select different sand pump types according to the actual operating conditions. The following is a list of different types of submersible sand pump selection under different construction conditions:

3.1 Submersible Sand Pumps in Common Use

The submersible sand pump is made of wear-resisting alloy steel with advanced structure. It has the characteristics of high efficiency, abrasion resistant, automatic coupling and long lifespan etc. It is powerful to discharge solid particles like sand and coal cinder, mainly used on the dredger, ship or boat for dredging and mineral waste residue transfer, bottom with extra agitator greatly improve the work efficiency.Submersible sand pumps are often applied on the dredger, ship or boat, it puts the electrical motor and mechanical pump on the same axis, the slurry pump bottom is equipped with a coaxial agitator. This agitated submersible slurry pump is developed and manufactured by Ocean Pump on basis of the fluid mechanic’s principles. The pump is made of wear-resisting alloy steel with advanced structure. It has the characteristics of high efficiency, abrasion resistant, automatic coupling and long lifespan etc. It is powerful to discharge solid particles like sand and coal cinder.

The initial design stage of the submersible sand pumps is mainly used for pumping fly ash, power plant sedimentation tanks and other operations, so the prototype of the submersible sand pumps are fully qualified for this operation. Since the stirring impeller is added at the bottom, mud or condensate can be breaking and disperse, so it can achieve stable operation at high concentrations.

Sometimes sedimentation ponds or the bottom of river channels have a long-term accumulation of primary sediment, Suggest to increase two or three shots of high-pressure water guns. The impact force of water gun can disperse the silt into the water to enhance the efficiency of sand extraction. The high-pressure water pump is recommended to supply 4-6 kilograms of pressure, and the power is slightly lower than the two specifications of the power for the submersible sand pump (for example: if the 22kw submersible sand pump is used, it can be matched with a high-pressure pump of 4.5-5kw).
If the clay layer is touched during the sand extraction process and the viscosity is strong, and the high-pressure water pump has a limited effect, an external side cutter can be used to mix directly to achieve the suction-type sand extraction method. The current power of the side mixer is from 4kw-22kw, can also be customized according to actual customer requirements.

Advantages:

Easy to use, highly efficient and stable, flexible to use
Disadvantages of the pump: high particle requirements, unable to extract large particles in winding solids

3.2 Large Particle Submersible Sand Pumps

The submersible sand pumps are designed specifically for working in challenging conditions that involve sand, mud, cobblestones, and similar materials. These pumps derive their impeller structure from closed slurry pumps, which can sometimes result in poor overflow performance and potential blockages. However, when dealing with mediums containing small and large particles, the selection of a semi-open impeller or a three-blade impeller structure can ensure continuous performance.

The large-particle submersible sand pumps offer advantages such as excellent overflow performance and high wear resistance. However, due to the low number of blades in these pumps, the shaft work efficiency is lower. Therefore, when selecting the appropriate pump, it is crucial to prioritize the specific working conditions at hand. It is not recommended to choose this type of pump for pumping sand or uniformly sized particles.

By carefully considering the specific characteristics of the medium and the desired performance requirements, the most suitable submersible sand pump can be selected to ensure efficient and reliable operation in various applications.

These pumps offer several advantages, including high durability, long service life, and a wide application range. However, it’s important to note that they have lower efficiency compared to the original submersible sand pumps, and the pump lift with the same power is slightly lower.

Despite these considerations, submersible sand pumps remain a valuable solution for handling challenging materials, providing efficient and reliable pumping in demanding environments.
Despite the lower efficiency and slightly reduced pump lift compared to the original submersible sand pumps, the advantages of these pumps make them valuable in various applications.
