The SJT‑CWP range consists of engineer‑to‑order high‑flow vertical pumps built for industrial pumping duties and custom sump layouts. Available with semi‑open or closed‑type cast impellers, the pump series starts at an impeller diameter of 350 mm (14 in), with a specific speed nq 75 (Ns 3 870). Primarily engineered as cooling‑water pumps for thermal‑power and combined‑cycle power plants, they are also suitable for water‑treatment and other industrial sectors.
