KVC 20/50 T

GENERAL DATA

Applications

Vertical multistage centrifugal pump suitable for use in small and medium water supply installations. Suitable for pressurization units, surge tank supply, rain irrigation and crop-dusting systems, fire-fighting and washing systems, conveyance of condensate and cooling water. Innovative and robust design.

Pump construction characteristics

KVC: Technopolymer discharge/suction bodies and in-line suction and discharge ports with threaded metal insert.

KVCX: technopolymer suction body with threaded metal insert; stainless steel threaded delivery port on pump jacket.

Impellers, diffuser bodies and diffusers in technopolymer, fully rust-proof.

Stainless steel AISI 304 pump jacket, adjustment rings and seal disk.

Carbon/ceramic mechanical seal, fitted on the AISI 303 stainless-steel drive shaft extension.

Motor construction characteristics

Asynchronous, closed motor cooled by external ventilation.
