The GRACO SE2B.1780 is a diaphragm pump designed for handling a wide range of fluids, including those with solids, in industrial and process applications. While specific details for the SE2B.1780 are not directly available, it is closely related to the SE2B.1814 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/Santoprene diaphragm, EPDM manifold O-ring
• Food, personal care, pharmaceutical (based on SE2B.1814; SE2B.1780 likely similar)
• Seal-less design for reduced maintenance and handling of abrasive materials
• Patented air charge reduces pulsation for smooth flow
• Electric operation for enhanced pump control
• Handles solids up to 3.8" (96.5 mm) in diameter (SE2B.1814; SE2B.1780 likely similar)
• Multiple internal elastomers for compatibility with various materials and cleaning chemicals
• Tri-clamp and sanitary DIN connections available

Applications:
Industrial fluid transfer, process applications, food, personal care, and pharmaceutical industries where reliable, low-maintenance pumping of fluids with solids is required.

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 materials with the fluid being pumped
• Follow manufacturer guidelines for air and electrical connections
• Regularly inspect diaphragms and seals for wear
• Use appropriate cleaning procedures for the intended application
• Regularly check and replace diaphragms as needed
• Inspect O-rings and seals for leaks or degradation
• Clean pump components according to industry standards
• Monitor for unusual noise or vibration during operation
