One mechanical failure every 346 years| Concrete

This is a section of the pull-out unit for a concrete volute pump; the unit has all of the mechanical components of the pump. Typical shaft diameters of the larger pumps are in the 12 to 16 inch range. The grease seals and the water seals, which are in the upper and lower bearing housings, are not shown to eliminate clutter.

What is a Volute? - Definition from Corrosionpedia

A volute is a spiral-shaped pump casing frequently used in centrifugal pumps. The purpose of the volute is to convert the liquid's velocity to pressure as the impeller discharges the liquid through the casing nozzle. This is achieved via a gradually increasing cross-sectional area in the volute that increases the fluid's flow-through area
