The GRACO SE2B.1640 is a diaphragm pump designed for sanitary applications, typically constructed with stainless steel and compatible elastomers for use in food, personal care, and pharmaceutical industries. It is intended for transferring fluids with high hygiene requirements and can handle solids up to a specified size.

Key Features:

• Diaphragm Pump
• Stainless steel (likely 316L) wetted section, multiple internal elastomers (e.g., PTFE, Santoprene, EPDM)
• Food, personal care, pharmaceutical applications
• Seal-less design for reduced maintenance and improved reliability
• Handles abrasive materials and solids up to 3.8" (96.5 mm) in similar models
• Patented air charge reduces pulsation for smooth flow
• Electric operation for additional control (in similar models)
• Tri-clamp and sanitary DIN connections available (in similar models)

Applications:
Transfer of fluids in sanitary environments such as food processing, personal care, and pharmaceutical manufacturing. Suitable for handling viscous, abrasive, or solid-laden fluids.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and maintains equipment warranties.
• Ensure proper alignment of inlet and outlet connections
• Use appropriate gaskets and clamps for sanitary connections
• Follow manufacturer’s guidelines for air supply and electrical connections (if applicable)
• Regularly inspect diaphragms and seals for wear and replace as needed
