The Husky 1050A is an air-operated double diaphragm pump designed for reliable transfer of fluids such as oils and waste oils. The specific variant referenced (1050A-E, PP/PT/PS/5A) typically features a polypropylene (PP) body with PTFE (PT) diaphragms and seats, and is intended for use in demanding industrial environments where chemical resistance and durability are required. This pump is commonly used in fluid reclamation, transfer, and dispensing applications within GRACO equipment.

Key Features:

• Pneumatic (air-operated) double diaphragm pump
• Husky 1050A, 1 in. NPT
• Polypropylene (PP) body, PTFE (PT) diaphragms and seats (specific to this variant; other materials available for different models)
• Maximum free flow delivery: 50 gpm (189 lpm) for metal/plastic variants; some listings specify 38–50 gpm depending on configuration[1][2][4]
• Maximum fluid working pressure: 100–125 psi (0.7–0.86 MPa, 7.0–8.6 bar) depending on variant; some listings specify 50 psi (0.35 MPa) for certain configurations[1][2][4]
• For use with oils, waste oils, and compatible with a wide range of industrial fluids (check chemical compatibility for specific fluids)
• UL listed (for certain configurations)[2][4]
• Stall-free low pulsation air valve for smooth and rapid changeover
• One-piece center section reduces leaks and maintenance
• Bolted design provides even sealing
• Longer diaphragm life (up to 5x longer in some configurations)
• Handles solids up to 1/8 in. (3.2 mm) in size
• Maximum cycle rate: 280 cpm
• Maximum suction lift: 16 ft (4.9 m) dry, 29 ft (8.8 m) wet

Applications:
Fluid reclamation, transfer, and dispensing of oils, waste oils, and compatible industrial fluids. Suitable for use in mining, agriculture, manufacturing, and other industrial settings.

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 inlet and outlet connections (1 in. NPT)
• Use recommended air pressure (20–100 psi, 0.14–0.7 MPa) for operation[4]
• Install with appropriate wall or drum mounting brackets as required
• Check for leaks and proper diaphragm seating after installation
• Follow manufacturer’s guidelines for maintenance intervals and diaphragm replacement
