CVP (Concrete Volute Pump) by Rodelta.

Concrete volute pumps, Rodelta type CVP, are pumps that are integrated in civil
constructions of pumping stations and are used for applications with a high flow rates
while delivering low to medium heads. The combination of steel fabricated rotor units in
volutes constructed in concrete makes it possible to pump more cubic meter of liquid
with less pump installations. At the same time ensuring higher reliability and efficiency.
