Description
The GRACO 651022 is a pneumatic (air-operated) double diaphragm pump constructed primarily from stainless steel, with an aluminum (AL) center section. It is designed for industrial fluid transfer applications, including water, antifreeze, and fuel, and is suitable for handling fluids with small solids.
Key Features:
- Pneumatic Diaphragm Pump
- Husky 1050, 1 in. (25.4 mm) NPT
- Stainless steel body, aluminum (AL) center section, PVDF seats, PTFE balls, PTFE diaphragm
- 50 GPM (Gallons per Minute) maximum
- Maximum fluid pressure: 0.86 MPa (approx. 125 psi) (Note: Some sources list 100 psi, but 0.86 MPa is approximately 125 psi; confirm with manufacturer for exact specification)
- Industrial fluids including water, antifreeze, fuel; compatible with fluids containing solids up to 0.125 in. (3.175 mm) in size
- UL listed
- Stall-free low pulsation air valve for smooth and rapid changeover
- Reliable and robust construction for industrial environments
- Easy to maintain with accessible components
- Designed for continuous duty cycle in demanding applications
Applications:
Industrial fluid transfer, including water, antifreeze, and fuel; suitable for environments requiring robust, corrosion-resistant pumps capable of handling small solids.
Installation Notes:
- Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
- Ensure proper alignment of pump components during assembly
- Use appropriate thread sealant for NPT connections
- Verify air supply is clean and within recommended pressure range
- Regularly inspect diaphragms and seals for wear and replace as needed
- Follow manufacturers recommended maintenance schedule
- Check for leaks and unusual noises during operation
- Keep air supply free of moisture and contaminants
- Replace diaphragms and seals at recommended intervals
