| dc.description.abstract | An ubiquitous multistage boiler feed water pump for a SMR Hydrogen Plant in a refinery was specified to meet feed water requirements at plant design hydrogen capacity and at a turndown rate. During testing, it was discovered that the pump could not meet the proposed NPSH3 values at rated or low flow conditions. The OEM offered two (2) options: 1. A complete redesign of the impeller and a delivery that would not meet the project requirements2. The installation of a stall ring in the eye of the 1st stage impeller.Due to project constraints, the stall ring option was chosen: however, multiple test runs and stall rings of varying diameter and entrance chamfers were required to provide a pump that would operate over the specified hydraulic performance envelope. | |
