The pump weight can be reduced by using steel instead of cast iron.

Comparison to the cast-metal vertical-shaft semi-axial flow pump
(In-house comparison)
Conventional pumps have been often made of cast iron, but these lightweight pumps are made of steel.
The material for the pump must be determined taking the variations in pump performance due to differences in material, the differences in corrosion resistance, and cost-effectiveness into account.
