The GRACO SE2B.1681 is a diaphragm pump designed for handling a wide range of fluids, including those with solids, in industrial and sanitary applications. While specific details for the SE2B.1681 are not directly available, it is closely related to the SE2B.1750 model, which features a seal-less design, 316L stainless steel wetted section, and compatibility with food, personal care, and pharmaceutical materials. The intended use is for reliable, low-maintenance fluid transfer in demanding environments.

Key Features:

• Diaphragm Pump
• Stainless steel (likely 316L) wetted section, PTFE and Santoprene diaphragms, PTFE ball/check material
• Food, personal care, pharmaceutical (based on SE2B.1750)
• Seal-less design for reduced maintenance and improved reliability
• Handles abrasive materials and solids (up to 3.8 in/96.5 mm for SE2B.1750)
• Patented air charge reduces pulsation for smooth flow
• Electric operation for enhanced pump control
• Multiple internal elastomers for chemical compatibility
• Tri-clamp and sanitary DIN connections available (SE2B.1750)

Applications:
Industrial fluid transfer, sanitary applications in food, personal care, and pharmaceutical industries, handling fluids with solids and abrasive materials.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure proper alignment of inlet and outlet connections
• Verify compatibility of wetted materials with the fluid being pumped
• Follow manufacturer guidelines for air supply and electrical connections
• Regularly inspect diaphragms and seals for wear and replace as needed
• Consult the equipment manual for specific installation and maintenance procedures
