The GRACO SE2B.1677 is a diaphragm pump designed for demanding industrial applications. While specific details for the SE2B.1677 are not directly available in the provided sources, it is closely related to the SE2B series, which are seal-less, self-priming, and stalling diaphragm pumps constructed with 316L stainless steel wetted sections and multiple elastomer options for compatibility with various materials and cleaning chemicals. These pumps are intended for use in food, personal care, and pharmaceutical industries for transferring fluids with solids.

Key Features:

• Diaphragm Pump
• 316L stainless steel wetted section, PTFE/Santoprene diaphragm, stainless steel seat, PTFE ball, EPDM manifold O-ring
• Food, personal care, pharmaceutical applications; handles solids up to 3.8" (96.5 mm) in diameter for SE2B series
• Seal-less design for reduced maintenance and improved reliability
• Patented air charge reduces pulsation for smooth flow
• Electric operation for precise pump control
• Ability to stall under pressure for system safety
• Tri-clamp and sanitary DIN connections available
• Multiple internal elastomers for chemical compatibility

Applications:
Ideal for in-process applications, filling systems, and sanitary/hygienic applications in food, beverage, personal care, and pharmaceutical industries.
