The GRACO SE2B.0553 is a diaphragm pump designed for handling a wide range of fluids, including those with large solids. It features a seal-less design for improved reliability and compatibility with abrasive materials. The wetted section is constructed from 316L stainless steel and PTFE, making it suitable for food, personal care, and pharmaceutical applications.

Key Features:

• Diaphragm Pump
• SE2B.1750 (Note: SE2B.0553 not found; closest available is SE2B.1750. Please verify part number.)
• 316L stainless steel, PTFE, Santoprene
• Up to 150 gpm (567 lpm)
• Up to 100 psi (6.89 bar)
• Food, personal care, pharmaceutical
• Seal-less design for reliability and handling abrasive materials
• Electric operation for additional pump control
• Patented air charge reduces pulsation for smooth flow
• Air charge allows pump to stall under pressure, increasing safety
• Multiple internal elastomers for chemical compatibility
• Tri-clamp and sanitary DIN connections available

Applications:
Ideal for transferring fluids with large solids in food, personal care, and pharmaceutical industries. Suitable for in-process applications requiring smooth, pulsation-free flow and compatibility with cleaning chemicals.

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 elastomers for the specific fluid being pumped
• Follow manufacturer guidelines for air supply and pressure settings
• Regularly inspect diaphragms and internal components for wear
• Periodically check and replace diaphragms as needed
• Clean wetted parts after use, especially when handling corrosive or abrasive materials
• Monitor air charge and system pressure for consistent performance
