The GRACO HE120-0661 is a high-performance electric diaphragm pump designed for demanding industrial applications. It features a 2" tri-clamp connection, is constructed with pharmaceutical-grade stainless steel (PH SST), and is intended for reliable, energy-efficient fluid transfer in hygienic and sanitary environments. The pump is suitable for use as a drop-in replacement for less-efficient pneumatic pumps or for new installations requiring robust, low-maintenance performance.

Key Features:

• Electric Diaphragm Pump
• QUANTM h120, 2" Tri-clamp
• Pharmaceutical-grade stainless steel (PH SST), FEP AL Center, SS Seat, PT Ball, PS Diaphragm
• Up to 450 lpm (liters per minute)
• Max. working pressure: 4.14 bar (414 kPa, 60 psi)
• Designed as a drop-in replacement for pneumatic diaphragm pumps; suitable for most fluid applications in hygienic and sanitary environments
• Pharmaceutical (PH) surface finish (20 Ra), 3A approved (32 Ra) for certain configurations
• No compressed air needed
