Vertical Multistage Pipeline Transfer Pump

The large-caliber vertical multistage pump sector has undergone strict energy efficiency standardization in recent years. Outdated cast iron large-flow pumps are being phased out due to rust pollution and excessive power consumption, while policy-driven green construction mandates widespread adoption of energy-efficient equipment. As super high-rise residential and commercial buildings multiply in cities worldwide, traditional small and medium caliber pumps fail to meet the large-volume water demand of clustered high-rise communities, creating a clear market gap for DN100 4-inch CDL models. Municipal water upgrading projects also require unified flange specifications for seamless pipeline transformation, making this DN100 Vertical Water Pump the standard supporting unit for high-rise pressure boosting.

1. All food-grade stainless steel wetted components avoid rust precipitation and secondary tap water pollution, fully compliant with global drinking water hygiene standards for municipal water supply projects.
2. DN100 oversized inline flange structure delivers ultra-large stable flow, exclusively tailored for centralized multi-story water supply of super-large residential blocks and municipal booster stations, eliminating flow shortage during morning & evening water consumption peaks.
3. Modular stacked impeller stage design supports free increase or reduction of stages, flexibly matching different building heights and municipal pipe network pressure demands without replacing the whole pump unit.
4. Compact vertical inline layout shares the same inlet and outlet axis, saving more than half of underground pump room space vs bulky horizontal large-flow pumps, greatly reducing civil engineering construction costs.
5. Optional 316L stainless overflow component upgrade adapts to slightly corrosive raw water such as coastal underground water, expanding application coverage for complex water quality working conditions.
