The GRACO 648017 Husky 1050A-E is a stainless steel air-operated double diaphragm pump with PTFE and PTS wetted parts, designed for reliable transfer of fluids including oils and waste oils. It is engineered for use in demanding industrial environments where chemical compatibility and durability are required.

Key Features:

• Pneumatic Diaphragm Pump
• 1050A-E
• Stainless Steel, PTFE, PTS, 4A (specific wetted parts configuration)
• Up to 50 GPM (189 LPM) for similar Husky 1050 models; actual for 1050A-E may vary, but typically in this range[1][5]
• Maximum fluid working pressure: 100–125 psi (0.7–0.86 MPa) for similar Husky 1050 models; 1050A-E may be rated for 50–125 psi depending on configuration (see documentation for exact rating)[1][4][5]
• Designed for use with oils, waste oils, and other compatible fluids; suitable for handling fluids with solids up to 1/8 in. (3.2 mm)[1][2][5]
• UL listed for certain configurations[2][5]
• Stall-free low pulsation air valve for smooth operation
• Robust construction for harsh environments
• Easy maintenance and serviceability
• Reliable performance with minimal downtime
• Handles abrasive and viscous fluids

Applications:
Ideal for fluid transfer, reclamation, and circulation in industrial, mining, agricultural, and vehicle service applications. Suitable for use with oils, waste oils, and other compatible fluids where chemical resistance and durability are required.

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
• Use recommended air pressure (typically 20–100 psi, 0.14–0.7 MPa) for optimal performance[5]
• Check for leaks and secure all fittings before operation
• Follow manufacturer’s guidelines for diaphragm and seat replacement intervals
• Regularly inspect and maintain wetted parts for wear and chemical compatibility
