The summary lists 40–200 mm caliber and 15–1200 kW, while its model table includes larger sizes and 1400 kW. Model-table values are retained here. Passage size is not a guaranteed allowable particle diameter; verify shape, concentration and manufacturer limits.
Q: flow; H: head; n: speed; η: efficiency. M denotes the catalog metal code. “—” means unavailable. Maximum power is not absorbed duty power; The high-head, vertical and gravel series list it maximum belt-drive power. Rows are not complete curves. Apply slurry corrections, cavitation checks and motor sizing.
