    Industrial pressure boosting applications and specialized water treatment facilities depend on highly reliable liquid handling. Facilities specify this centrifugal multistage pump to support complex automated machinery and safely transfer moderately aggressive fluids across operational zones.

    System capabilities establish a Max Head 157 m alongside a steady Max Flow 73.3 L/Min. Electrical input consists of a 2.12 kW motor utilizing a strictly 415v three-phase connection. Physical pipework relies on 25 mm dimensioning for the suction and discharge manifolds.

    Internal liquid routing is managed through an efficient end-suction layout designed to minimize mechanical turbulence. The tightly spaced closed impeller series decreases axial thrust, sustaining predictable volumetric displacement and minimizing internal pressure loss during heavy usage.

    Forged from full AISI 316L stainless steel, the essential wetted components defend against environmental fatigue. External protection is achieved through an air-cooled squirrel-cage motor enclosure carrying an IP 55 rating, combined with an essential O-ring mechanical seal.
