The GRACO Husky 1050A is an air-operated double diaphragm pump designed for reliable transfer of fluids such as oil and waste oil. It features an aluminum fluid section and is intended for use in demanding industrial environments where robust, low-maintenance fluid handling is required.

Key Features:

• Pneumatic Diaphragm Pump
• Husky 1050A
• Aluminum fluid section, Buna-N (Nitrile) seats, TPE diaphragms (varies by configuration)
• Up to 50 GPM (189 LPM) depending on configuration; some models specify 38 GPM
• Maximum fluid working pressure: 50–125 psi (0.35–0.86 MPa) depending on configuration; most common is 50 psi (0.35 MPa) for UL-listed models
• For use with oil, waste oil, and compatible fluids; not for use with highly corrosive or incompatible chemicals unless specified
• UL-listed for certain models
• Stall-free, low pulsation air valve for smooth operation
• Reliable, low-maintenance design
• Handles solids up to 1/8 in. (3.2 mm)
• Easy to maintain and repair
• Suitable for continuous or intermittent duty cycles

Applications:
Ideal for fluid transfer, oil dispensing, waste oil recovery, and general industrial pumping applications. Commonly used in vehicle service, mining, agriculture, and manufacturing environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and warranty compliance. Non-genuine parts may compromise pump reliability and safety.
• Ensure proper alignment of inlet and outlet connections (typically 1 in. NPT)
• Use recommended air pressure (20–100 psi, 0.14–0.7 MPa) for best performance
• Check for leaks and secure all fittings before operation
• Follow manufacturer guidelines for diaphragm and seat replacement intervals
• Regularly inspect for wear and replace consumable parts as needed
• Inspect diaphragms and seats regularly for wear or damage
• Lubricate moving parts as specified in the manual
• Keep air supply clean and dry to prevent valve issues
• Store pump in a clean, dry environment when not in use
