The Goulds centrifugal 3657 series is commonly used for pure water transfer, chemical transfer, pharmaceutical procedures or food and beverage processing. This series features materials made of superior construction. Liquid end components consist of precision investment cast 316 stainless steel for added corrosion resistance and strength. Casing for this series features an investment cast AISI type 316 stainless steel volute design for maximum efficiency. Vertical discharges come standard but are field modifiable to four standard positions. The frame mounted design allows for flexibility of installation and driver arrangements. Mechanical seals are standard Flowserve 31 seals with carbon versus silicon-carbide faces, Viton elastomers, and 316 stainless steel metal parts. Optional seals are available for high temperature and mild abrasive services. A close-coupled, compact design saves space and simplifies installation. An enclosed impeller allows for maximum efficiency and service life with no need for clearance adjustment. The back pull out design also simplifies maintenance by allowing the casing to remain in the piping during disassembly. Shafts and sleeves are comprised of high strength steel. Motors in this series are NEMA standard JM or T frames that are available in both single and three phase designs with a variety of enclosures and voltage to match your service requirements.
