The GRACO SE2B.1850 is a diaphragm pump designed for demanding industrial applications. While specific details for the SE2B.1850 model are not fully detailed in available sources, it is closely related to the SE2B series, which features a seal-less, self-priming design with a stainless steel wetted section 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 and handling solids.

Key Features:

• Diaphragm Pump
• Stainless steel wetted section, PTFE/Santoprene diaphragm, EPDM manifold O-ring
• Food, personal care, pharmaceutical applications
• Seal-less design for reduced maintenance and improved reliability
• Handles abrasive materials and solids (up to 3.8" in SE2B.1814)
• Patented air charge reduces pulsation for smooth flow
• Electric operation for precise pump control
• Multiple internal elastomers for chemical compatibility
• Tri-clamp and sanitary DIN connections available

Applications:
Transfer of fluids in food, beverage, personal care, and pharmaceutical industries; handling of abrasive or solid-laden fluids.

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 pneumatic connections
• Regularly inspect and maintain seals and diaphragms for longevity
• Periodically check for wear on diaphragms and seals
• Clean wetted parts according to industry standards
• Monitor pump performance and address any leaks or pulsation issues promptly
