Self-priming Centrifugal Pump

• Water supply and drainage for industrial and mining enterprise
• Water supply and drainage for construction projects
• Agricultural irrigation and drainage
• Sewer and septic tank drainage
• Sewage transportation for sewage treatment plants
• MBR membrane suction use

• Small size, light weight, small space occupation, easy to install
• The pump body of self-priming centrifugal pump has a special structure and high self-priming ability.
• Self-priming centrifugal pump adopts a rear pull-out structure, which is easy to maintain.
• The semi-open impeller structure has a strong ability to transport sewage and impurities.
• Self-priming centrifugal pump adopts a mechanical seal, no leakage, and is with a long service life.
• Easy to use: just install the pump on the side of the pool and put the suction pipe below the liquid surface to work (the pump needs to be filled with water before the first operation).
