About this file
This is a Questions and Answers document providing technical specifications for a pump system intended for a dew chamber application.
The document specifies that the required pump must accommodate a 4.625-inch impeller rotating at 3450 rpm, though no specific flow rate is provided in the requirements. The pump will handle water as the working fluid within a normal operating temperature range of 2–35°C, with typical operations at 4°C. The system has a maximum working pressure of 175 psi. The document includes a pump performance curve chart indicating the duty point for the existing dew chamber system, marked with a red indicator at approximately 55 US gpm and 75 feet of head. The performance curve displays multiple efficiency contours (ranging from approximately 40% to 55% efficiency) and includes horsepower requirement lines (1.5 hp, 2 hp, and 3 hp), providing comprehensive guidance for pump selection that meets the specified operating conditions.
