ALLWEILER – NISM65-250 – VOLUTE CASING CENTRIFUGAL PUMP

The Allweiler NISM65-250 is a highly reliable, single-stage volute casing centrifugal pump designed for inline vertical installation on marine vessels and industrial fluid systems. Engineered to optimize space, this close-coupled, self-priming pump features a block design that eliminates the need for separate shaft alignment, reducing vibration and wear. It is built to move low-viscosity, clean, or slightly contaminated liquids like fresh water, sea water, and condensates. Its pull-out design allows the complete insert unit to be removed without disconnecting the casing from the piping, simplifying routine maintenance.
