Goulds Water Technology Pump Models 3657 / 3757 are designed for multiple application and have several fetures and benefits.

• Superior Materials of Constructions: Precision investment cast 316 stainless steel liquid end components for corrosion resistance and strength.
• Frame Mounted Design: Flexibility of installation and driver arrangements.
• Enclosed Impeller Design: Maximum efficiency and service life with no need for clearance adjustment. Key driven shaft connection with locknut.
• Back Pull-Out Design: Simplifies maintenance by allowing the casing to remain in the piping during disassembly.
• Close-Coupled Design: Compact design saves space and simplifies installation.
• Casing features: Investment cast AISI type 316 stainless steel, volute design for maximum efficiency. Vertical discharge standard, field modifiable to four standard positions.
• Shaft and Sleeve: High strength steel, keyed design non-wetted. Protected from pumpage by O-ring seal and hooked design AISI type 316 stainless steel shaft sleeve.
• Mechanical Seals: Standard John Crane Type 21 seal with carbon versus ceramic faces, Viton elastomers and 316 stainless steel metal components. Options are available for high temperature and mild abrasives.
• Drive Motors: NEMA standard JM frame (close coupled) or T frame (frame mounted) are available in both single and three phase with a variety of enclosures and voltages to match your service requirements.

3657 / 3757 Gould Pump Models have an Enclosed Impeller and are 316 Stainless Steel End Suction Centrifugal Pumps
