SP and SPR pumps are vertical centrifugal slurry pumps that are immersed underwater and used to transport abrasive, coarse particle, and high concentration slurry. It does not require any shaft seal or shaft seal water, and can work normally even when the inlet volume is insufficient.

The SP type pump body is made of wear-resistant metal, and the impeller is made of wear-resistant metal or rubber, made of polyurethane material.

The SPR type pump has rubber lined components immersed in the liquid, which is suitable for transporting corrosive slurry.

Model meaning:

40PV - SP (or SPR)

40——泵吐出口直径（毫米）

PV - Vertical Bracket

SP - Subsea slurry pump

SPR - Bottom Slurry Pump for Rubber lined Liquid

Structural features:

1. Adopting a vertical cantilever and single pump casing structure.

2. Double suction, semi open impeller design, using hard alloy or rubber impellers.

3. The cylindrical bearing component is designed with high-capacity bearings and lubricated with grease.

4. The gap between the impeller and the guard plate can be adjusted to ensure the efficient operation of the pump.

5. No shaft seal is required.

6. Pumps and drivers can be equipped with direct drive or V-belt drive.

7. The RVS type uses rubber overcurrent components and rubber lining for components in contact with the slurry, which is suitable for strong corrosive working conditions.

Product use: Mainly suitable for conveying corrosive, coarse particles, and high concentration slurry. Widely used in metallurgy, mining, coal, electricity, building materials, environmental protection and other sectors.
