The GRACO 1050A-E is a stainless steel air-operated double diaphragm pump designed for reliable fluid transfer in demanding industrial environments. It is intended for use with a variety of fluids, including oils and waste oils, and is engineered for durability and ease of maintenance within GRACO equipment.

Key Features:

• Pneumatic Diaphragm Pump
• Husky 1050A-E
• Stainless Steel (SS), with options for CW (Chemical Wet), CO (Chemical Oil), and 5B (specific configuration or material option)
• Maximum free flow delivery: 50 gpm (189 lpm) for metal pumps; some listings specify up to 38 gpm for certain configurations[1][2][4]
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa) for metal pumps; some listings specify 50–100 psi for specific models[1][2][4]
• For use with oil, waste oil, and compatible with a wide range of industrial fluids; suitable for handling solids up to 1/8 in (3.2 mm)[1][2][4]
• UL listed for certain models[2][4]
• Stall-free low pulsation air valve for smooth operation
• Robust construction for long service life
• Easy maintenance with accessible components
• Handles abrasive and viscous fluids
• Suitable for continuous and intermittent duty cycles

Applications:
Industrial fluid transfer, oil and waste oil handling, fluid reclamation, and general-purpose pumping in mining, agriculture, and manufacturing environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise reliability and void warranties.
• Ensure proper alignment of inlet and outlet connections (commonly 1 in. NPT)
• Verify air supply is within the recommended operating range (typically 20–100 psi)
• Check for leaks and secure all fittings before operation
• Follow manufacturer’s guidelines for diaphragm and seat material selection based on fluid compatibility
• Regularly inspect and maintain diaphragms, seats, and valves for wear
• Use only recommended lubricants and replacement parts
• Monitor pump cycle rate for optimal performance and longevity
• Keep pump and surrounding area clean to prevent contamination
• Consult the manual for specific maintenance intervals and procedures
