Centrifugal pump NCR

for hydrocarbonsoilfor chemicals

Description
The NCR is a single-stage volute-casing centrifugal pump designed for process applications and manufactured to API 610, OH2 configuration. It has an axial suction nozzle and a centerline, vertically upward discharge nozzle. The casing includes integrally cast supports for a mid-shaft bearing housing and a welded, flanged drain. Atmospheric sealing uses metal-to-metal profile rings; the seal chamber accepts API 682 mechanical seals.
