The GRACO HE120-0657 is an electric diaphragm pump designed for industrial fluid transfer applications. While specific details for the HE120-0657 variant are not fully detailed in available sources, it is closely related to the QUANTM h120 series, which features a 316L stainless steel fluid section and is intended for use in demanding environments requiring reliable, efficient, and quiet operation. The pump is engineered to replace traditional air-operated diaphragm pumps, offering significant energy savings and improved process control.

Key Features:

• Electric diaphragm pump
• 316L stainless steel fluid section, FEP-coated aluminum electric drive, PTFE ball, PTFE/Santoprene 2-piece diaphragm, EPDM manifold o-ring
• Designed to replace air-operated diaphragm pumps in industrial applications
• CID1 Groups C,D,T4 Zone 1 AEx d b IIB T4 Gb hazardous location approval (for similar models in series)
• Efficient electric motor with up to 80% reduction in energy consumption compared to pneumatic pumps
• Compact and efficient electric drive with comparable footprint to pneumatic diaphragm pumps
• Quiet operation reduces plant noise and improves employee safety
• Smart pump control for accurate flow set points and built-in I/O
• AutoPrime feature and stalling under pressure for safety
• Easy maintenance and reliable performance

Applications:
Industrial fluid transfer, including food, beverage, chemical, and pharmaceutical processing; suitable for applications requiring quiet, efficient, and reliable pumping of sensitive or abrasive fluids

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety, and maintains warranty coverage
• Ensure electrical supply matches pump specifications (e.g., 200-240 VAC for similar models)
• Follow all local electrical and safety regulations
• Inspect all connections and seals before operation
• Refer to the specific installation manual for detailed instructions
• Regularly inspect diaphragm, seals, and internal components for wear
• Use only recommended replacement parts
• Keep pump and surrounding area clean to prevent contamination
• Monitor for unusual noise or vibration and address promptly
