Description
The GRACO SE4F.0020 (and likely SE4F.0021, as SE4F.0021 is not directly listed but is a closely related part number) is a seal-less diaphragm pump designed for handling large solids and abrasive materials. It features a 316L stainless steel wetted section and multiple internal elastomers for compatibility with various materials and cleaning chemicals. This pump is intended for use in food, edible oil, and personal care applications, providing reliable transfer of fluids with large particulates.
Key Features:
- Diaphragm Pump
- SE4F.0020 (SE4F.0021 likely similar)
- 316L stainless steel wetted section, PTFE/Santoprene diaphragms, EPDM O-rings
- Up to 150 gpm (567 lpm)
- Up to 100 psi (6.89 bar)
- Edible oil, food, personal care
- Seal-less design eliminates rotary shaft seal issues and handles abrasive material
- 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
- Tri-clamp and sanitary DIN connections available
- Handles solids up to 3.8″ (96.5 mm) in diameter
Applications:
Ideal for transferring fluids with large solids in food, edible oil, and personal care industries. Suitable for in-process applications requiring smooth, pulsation-free flow and compatibility with cleaning chemicals.
Installation Notes:
- Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
- Ensure proper alignment of inlet and outlet connections (4″ tri-clamp or sanitary DIN)
- Verify compatibility of elastomers with process fluids and cleaning chemicals
- Follow manufacturer guidelines for air supply and electrical connections
- Regularly inspect diaphragms and O-rings for wear and replace as needed
