The GRACO SE2B.1851 is a diaphragm pump designed for industrial fluid transfer applications. While specific details for the SE2B.1851 are not directly available in the provided sources, it is closely related to the SE2B.1814 and SE2B.1850 models, which are seal-less, electric diaphragm pumps with stainless steel and PTFE wetted parts, suitable for handling abrasive and corrosive materials in food, personal care, and pharmaceutical industries.

Key Features:

• Diaphragm Pump
• Stainless steel (likely 316L) and PTFE wetted parts
• Food, personal care, pharmaceutical (based on similar models)
• Seal-less design for reduced maintenance and handling of abrasive materials
• Electric operation for precise pump control
• Patented air charge for smooth outlet flow and system safety
• Multiple internal elastomers for chemical compatibility
• Tri-clamp and sanitary DIN connections available (based on similar models)

Applications:
Industrial fluid transfer, especially in food, personal care, and pharmaceutical industries where hygiene and chemical compatibility are critical.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure all connections are secure and compatible with the pump’s inlet/outlet standards (likely tri-clamp or sanitary DIN)
• Follow manufacturer guidelines for electrical and air connections
• Regularly inspect diaphragms and internal elastomers for wear and chemical compatibility
• Consult the equipment manual for specific installation and maintenance procedures
