Description
The GRACO SE2B.1872 is a diaphragm pump designed for industrial applications, featuring a seal-less design and constructed with 316L stainless steel and PTFE wetted parts. It is intended for handling abrasive, viscous, or solids-laden fluids in food, personal care, and pharmaceutical industries.
Key Features:
- Diaphragm Pump
- SE2B.1872 (Note: SE2B.1814 is the closest available model; SE2B.1872 is not directly listed in available sources, but SE2B series is referenced)
- 316L stainless steel wetted section, PTFE and Santoprene diaphragm, EPDM manifold O-ring
- Food, personal care, pharmaceutical applications
- Seal-less design for handling abrasive materials and eliminating rotary shaft seal issues
- Electric operation for enhanced pump control
- Patented air charge reduces pulsation for smooth outlet 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 transferring abrasive, viscous, or solids-laden fluids in food, personal care, and pharmaceutical industries. Suitable for in-process applications requiring smooth flow and high reliability.
Installation Notes:
- Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
- Ensure all connections (fluid inlet/outlet, air inlet) are properly secured and compatible with the pumps specifications
- Follow manufacturer guidelines for installation and maintenance to prevent leaks and ensure long service life
- Regularly inspect diaphragms and elastomers for wear and replace as needed
- Use appropriate cleaning chemicals compatible with the pumps wetted materials
