A vertical, non-self-priming, multistage, in-line centrifugal pump designed for installation in pipe systems and mounting on a foundation. All wetted components are constructed from high-grade stainless steel (EN 1.4401 for impellers, intermediate chambers, and outer sleeve; EN 1.4408 for head cover and base), providing exceptional corrosion resistance and durability. The pump delivers a rated flow of 30 m³/h and a rated head of 29.5 meters, with a maximum head of 39.5 meters. It features a single HQQV shaft seal complying with EN 12756, DIN flanged connections (DN 65, PN 40), and a maximum operating pressure of 16 bar. Power is transmitted via a cast iron split coupling from a 4 kW, IE3-class, 3-phase AC motor with IP55 enclosure protection.
