The GRACO SE2B.1815 is a double diaphragm pump designed for industrial fluid transfer, featuring a seal-less design and 316L stainless steel wetted section. It is intended for use in applications requiring the handling of abrasive or corrosive materials, especially in food, personal care, and pharmaceutical industries.

Key Features:

• Double Diaphragm Pump
• SE2B.1815 (size not explicitly specified, but similar models have 2-inch inlet/outlet)
• 316L stainless steel wetted section, PTFE and Santoprene diaphragms, EPDM manifold O-ring, PTFE ball/check material
• Up to 150 gpm (567 lpm) (based on SE2B series; not explicitly confirmed for SE2B.1815)
• Up to 100 psi (6.89 bar) (based on SE2B series; not explicitly confirmed for SE2B.1815)
• Food, personal care, pharmaceutical materials; compatible with various cleaning chemicals
• Seal-less design for reduced maintenance and improved reliability
• Handles solids up to 3.8" (96.5 mm) in diameter
• Patented air charge reduces pulsation for smooth flow
• Electric operation for enhanced pump control
• Air charge allows pump to stall under pressure, increasing safety
• Tri-clamp and sanitary DIN connections available
• Multiple internal elastomers for chemical compatibility

Applications:
Ideal for transferring abrasive, corrosive, or viscous fluids in food, personal care, and pharmaceutical processing. Suitable for in-process applications requiring smooth, pulsation-free flow and the ability to handle large solids.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure proper alignment of inlet and outlet connections
• Use compatible gaskets and seals for the intended application
• Follow manufacturer guidelines for air supply and electrical connections
• Regularly inspect diaphragms and internal elastomers for wear
• Maintain recommended air pressure and flow rates for best performance
