Goulds 3796 3 Priming and Air Separation Accomplished Within Casing Dual volute design primes suction with only an initial charge of liquid in the casing. During priming cycle, the lower volute functions as an intake while upper volute discharges liquid and entrained air into separation chamber. Air is separated and expelled through pump discharge while liquid recirculates into lower volute. Once air is completely removed from suction and liquid fills impeller eye, pump is fully primed, and functions as a conventional centrifugal pump with both volutes performing as discharges. The casing is...

10 Goulds Power Ends are the result of 160 years of design experience, customer interaction, and continuous improvement. Customers get extended Mean Time Between Failure (MTBF) and lower life cycle costs (LCC)… guaranteed! 2 1 5 2 4 3 Goulds Patented Power Ends Extended Pump Life Through Intelligent Design 1 The heart of the , the condition monitor unit continuously measures vibration and temperature at the thrust bearing and automatically indicates when pre-set levels of vibration and temperature have been exceeded, so that changes to the process or machine can be made before failure occurs....

11 Shaft and Bearings Engineered for Maximum Reliability The rugged shaft and bearing combination maintains shaft deflection of less than 0.002 inches at all operating points. The result is longer seal and bearing life. Premium severe-duty thrust bearings increase bearing fatigue life by 2-5X. • High purity steels have fewer inclusions than standard steel — better grain structure and wear resistance. • Heat treatment of bearing elements increases hardness for increased fatigue life. Forty-degree contact angle on the thrust bearing for higher thrust load capability. • 35% higher dynamic load rating...
