The GRACO SE2B.1750 is a seal-less diaphragm pump designed for reliable, low-maintenance transfer of fluids in demanding industrial environments. Its wetted section is constructed from 316L stainless steel and PTFE, making it suitable for handling food, personal care, and pharmaceutical materials. The pump is engineered to handle solids up to 3.8 inches in diameter and is compatible with a wide range of cleaning chemicals.

Key Features:

• Diaphragm Pump
• SE2B.1750
• 316L stainless steel wetted section, PTFE and Santoprene diaphragm, stainless steel and PTFE ball/check, EPDM manifold O-ring
• Up to 150 gpm (567 lpm)
• Up to 100 psi (6.89 bar)
• Food, personal care, pharmaceutical industries; compatible with various cleaning chemicals
• Seal-less design eliminates rotary shaft seal issues and handles abrasive materials
