Casing: single volue casing with working pressure up to 16bar.
Impeller: fully open, semi-open, three blades for a large open cross section. Six blades for high pressures and low pulsations.
Two wear ring: to pretect the pump casing and casing cover.
Shaft: ensure minor shaft deflection and low mechanical vibrations.
