Vertical Multistage Pressure Maintenance Pump

The large-caliber vertical multistage pump industry faces two prominent market gaps: conventional DN100 and below pumps fail to meet ultra-high flow demands of desalination and industrial central cooling loops, while most seawater dedicated pumps adopt bulky horizontal structures that occupy excessive factory and platform space. Global marine resource development and coastal urban expansion drive rising demand for dual-purpose compact vertical pumps that can switch between fresh water and saltwater media. Policy restrictions on rust-prone cast iron pumps push infrastructure clients to adopt stainless steel DN125 vertical multistage Pump; the 5-inch CDL fills this niche, optimized as a compact vertical multistage centrifugal pump with modular material upgrade to convert into a fully functional seawater resistant pump without redesigning the pump body. Energy efficiency regulations worldwide also accelerate the phase-out of low-efficiency large-flow pumps.

1. Entire flow passage adopts 304/316 stainless steel, anti-rust, anti-corrosion, free of secondary water pollution
2.5-inch standard size matching mainstream pipeline installation, flexible multi-stage combination to customize lifting head
3.Wide pressure regulation range, perfectly meets high-rise water supply, water treatment and industrial circulation boosting demands
4.Precision cast stainless steel impeller and diffuser with optimized hydraulic model, low flow loss
5.Small floor occupation, no complex foundation required; applicable for narrow equipment rooms, water pump cabinets and integrated water supply units
6.Closed fan-cooled motor with sound insulation design, operating noise far below national industrial standards
7.Modular split structure, disassembly and replacement of wearing parts without removing the whole pump from pipeline
8.Anti-oxidation stainless steel shell, resistant to humid, acid and mild alkali working environments
9.Tight sealing performance, zero liquid leakage under rated working pressure
