The GRACO HE120-0332 is an electric diaphragm pump designed for reliable, efficient fluid transfer in demanding industrial environments. It features a 316L stainless steel fluid section with a tri-clamp center port, FEP-coated aluminum electric drive, and Buna-N (BN) ball and diaphragm. This pump is engineered for use as a highly reliable drop-in replacement for less efficient pneumatic pumps or as a new installation in process lines requiring sanitary, robust, and energy-efficient pumping solutions.

Key Features:

• Electric Diaphragm Pump
• QUANTM h120, 2" Tri-clamp
• 316L stainless steel fluid section, FEP-coated aluminum electric drive, Buna-N ball and diaphragm, Buna-N manifold o-ring
• 450 lpm (liters per minute)
• Max. working pressure: 4.2 bar
• Designed as a drop-in replacement for pneumatic diaphragm pumps; suitable for most fluid applications
• EN 3.1 material certification, 20 Ra surface finish (Pharmaceutical grade)
• Revolutionary electric motor design for up to 80% energy savings
• Self-priming, seal-less design for smooth and steady flow

• Smart pump control for accurate flow set points and built-in I/O
• Easy installation and maintenance
• AutoPrime feature

Applications:
Ideal for process industries requiring sanitary, reliable, and energy-efficient fluid transfer, including food, beverage, pharmaceutical, and chemical applications. Suitable for both new installations and as a replacement for existing pneumatic pumps.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure proper alignment and secure mounting of the pump
• Verify electrical supply matches pump specifications (200-240 VAC, 1Ph)
• Use appropriate tri-clamp fittings for sanitary connections
• Follow manufacturer guidelines for initial priming and start-up
• Regularly inspect and maintain seals and diaphragms for optimal performance
• Perform preventative maintenance to ensure peak performance and longevity
• Monitor for signs of wear or leaks
• Replace worn components with genuine GRACO parts
• Keep pump and surrounding area clean to prevent contamination
