Description
The GRACO SE2B.1921 is a diaphragm pump designed for transferring fluids in industrial applications. While specific details for the SE2B.1921 model are not directly available in the provided sources, it is closely related to the SE2B series, which features a seal-less design, robust construction, and compatibility with a range of materials. The SE2B series is typically constructed with stainless steel and PTFE wetted parts, making it suitable for handling abrasive, viscous, or sensitive fluids in food, personal care, and pharmaceutical industries.
Key Features:
- Diaphragm Pump
- Stainless steel and PTFE wetted parts (based on SE2B series)
- Food, personal care, pharmaceutical (based on SE2B series)
- Seal-less design for reduced maintenance and improved reliability
- Handles solids up to 3.8″ (96.5 mm) in diameter (SE2B.1110; SE2B.1921 may differ)
- Patented air charge reduces pulsation for smooth flow
- Electric operation for enhanced control
- Multiple internal elastomers for chemical compatibility
- Tri-clamp and sanitary DIN connections available (SE2B.1110; SE2B.1921 may differ)
Applications:
Transfer of viscous, abrasive, or sensitive fluids in food, personal care, pharmaceutical, and industrial processing applications.
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 fittings and connections for your application
- Follow manufacturer guidelines for electrical and air supply connections
- Regularly inspect and maintain seals and diaphragms as per maintenance schedule
- Consult the equipment manual for specific installation and maintenance instructions
- Use only compatible fluids and chemicals as specified by GRACO
- Monitor pump performance and address any leaks or unusual noises promptly
