The GRACO SE2B.1750 is a diaphragm pump designed for handling fluids with large solids, constructed primarily from 316L stainless steel and PTFE/Santoprene for the diaphragm. It is intended for use in process applications requiring reliable, seal-less pumping of abrasive or sensitive materials, especially in food, personal care, and pharmaceutical industries.

Key Features:

• Diaphragm Pump
• SE2B.1750 (note: SE2B.1728 is not directly listed; SE2B.1750 is the closest match with available data)
• 316L stainless steel wetted section, PTFE/Santoprene diaphragm, PTFE ball/check, EPDM manifold O-ring
• Up to 150 gpm (567 lpm)
• Up to 100 psi (6.89 bar)
• Food, personal care, pharmaceutical materials
• Seal-less design for handling abrasive materials and reducing maintenance
• Electric operation for enhanced pump control
• Patented air charge reduces pulsation for smooth flow
• Air charge allows pump to stall under pressure, increasing safety and eliminating need for circulation loops
• Multiple internal elastomers for compatibility with various materials and cleaning chemicals
• Tri-clamp and sanitary DIN connections available

Applications:
Ideal for process applications in food, personal care, and pharmaceutical industries where handling of large solids, abrasive, or sensitive materials is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure proper alignment and secure mounting of the pump
• Use recommended gaskets and seals for sanitary connections
• Follow manufacturer guidelines for electrical and air supply connections
• Regularly inspect diaphragms and internal components for wear and replace as needed
• Periodically check and maintain air charge system
• Clean wetted parts according to industry and material standards
• Inspect for leaks and ensure all connections remain tight
• Replace diaphragms and seals at recommended intervals
