Structural Features and Applicable Working Conditions of Vertical Slurry Pumps

The pump shaft of a vertical slurry pump is perpendicular to the horizontal plane. Since vertical slurry pumps are typically used in slurry pits to pump slurry, the pump head must be submerged below the liquid surface, hence the alternative name ‘submerged slurry pump.’ However, not all components are fully submerged; if the motor and other non-pump head components are also submerged in the slurry, the pump is referred to as a ‘submersible slurry pump.’ Do you know the typical applications and operating conditions for vertical slurry pumps?

Vertical slurry pumps are primarily used for conveying corrosive, coarse-particle, high-concentration slurry. They are widely applied in industries such as metallurgy, mining, coal, power, construction materials, and environmental protection.

What are the structural features of vertical slurry pumps?

1. Wet-end components:

This series of pumps are vertical slurry pumps primarily designed for submerged operation in liquid environments. Their design ensures high efficiency, wear resistance, and corrosion resistance, making them suitable for slurry conveyance in various industrial applications. The pump body is constructed from high-quality wear-resistant metal materials to ensure durability and stability. The impeller is manufactured from wear-resistant metals or materials such as rubber and polyurethane to withstand high pressures and friction during conveyance.

The unique feature of the  SPR type pump is that all components submerged in liquid are lined with rubber, enhancing its corrosion resistance and making it particularly suitable for conveying corrosive slurry. This design not only extends the pump's service life but also reduces maintenance costs, providing users with higher economic benefits.

2. Bearing Assembly: To ensure smooth bearing operation, the bearing assembly uses grease lubrication, effectively reducing friction and extending bearing service life. Based on the varying liquid levels in the slurry tank, we offer pumps with shafts and suction pipes of different lengths to meet the requirements of various operating conditions.

When the water depth in the slurry tank is particularly high, we can provide custom-lengthened shafts to meet specific application needs. These custom shafts are designed and manufactured according to your specific requirements to ensure pump performance and stability.

3. Shaft seal (sealing): No shaft seal or seal water is required, and the pump can operate normally even under insufficient suction conditions. This feature of the vertical slurry pump significantly reduces the failure rate during use and enhances the pump's reliability. As a result, this pump has found widespread application in various industrial sectors, such as chemicals, petroleum, and power generation.

4. Drive method: This product offers multiple drive methods to accommodate different operational requirements. These include V-belt drive, which utilises the shape and structure of the V-belt to transmit motor power to other equipment. Additionally, there is elastic coupling drive, which connects the motor to other equipment via the elastic elements of the elastic coupling to achieve power transmission. Both drive methods feature simple structures and convenient maintenance, effectively improving equipment operational efficiency and reliability.

5. Overall Performance: The pump incorporates multiple speed designs and various modification options to ensure optimal operating conditions, thereby extending service life and improving operational efficiency. It can withstand harsh conveying conditions, with its internal structure and material selection carefully designed and optimised to maintain excellent performance and reliability even under severe conditions.
