The GRACO 648067 Husky 1050A-E is an electric double diaphragm pump with a 1" NPT inlet/outlet, constructed primarily from aluminum with Buna-N (nitrile) seats, balls, and diaphragms. It is designed for reliable, efficient transfer of fluids in industrial and maintenance applications, particularly where ATEX certification is required for hazardous environments.

Key Features:

• Electric Double Diaphragm Pump
• Husky 1050A-E, 1" NPT
• Aluminum fluid section and center section, Buna-N seats, balls, and diaphragms
• Max. 158 l/min (not all sources agree; some list 189 l/min for air-operated versions, but electric model is typically 158 l/min)
• Max. output pressure: 70 psi
• Designed for industrial fluid transfer, compatible with a range of fluids suitable for aluminum and Buna-N materials
• ATEX certified (for use in explosive atmospheres)
• Stall-free, low pulsation operation for smooth flow
• Reliable, robust construction for demanding environments
• Easy maintenance with accessible components
• Suitable for continuous duty cycles

Applications:
Ideal for transferring oils, waste oils, and other compatible fluids in industrial, mining, agricultural, and maintenance settings. Suitable for hazardous environments requiring ATEX certification.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and warranty compliance.
• Ensure proper alignment of inlet and outlet connections
• Verify compatibility of fluid with pump materials (aluminum, Buna-N)
• Follow local electrical and safety regulations, especially in ATEX environments
• Regularly inspect diaphragms, seats, and balls for wear and replace as needed
• Use appropriate mounting hardware for secure installation
