The Husky 1050A is an air-operated double diaphragm pump designed for transferring fluids such as oil and waste oil. It features an aluminum body and is intended for use in fluid handling and reclamation applications within GRACO equipment.

Key Features:

• Pneumatic Diaphragm Pump
• 1050A
• Aluminum body, Buna-N (BN) seats and diaphragms (as per part number suffix)
• Maximum flow rate: 38–50 GPM (varies by configuration and pressure; 50 GPM is typical for aluminum models at full air pressure)[2][4][1]
• Maximum fluid working pressure: 50–125 psi (varies by configuration; 50 psi for UL-listed models, 125 psi for standard metal models)[2][1][5]
• For use with oil, waste oil, and compatible fluids; not for use with incompatible chemicals or solvents
• UL-listed (for certain models)[2][4]
• Stall-free low pulsation air valve for smooth and rapid changeover
• Handles solids up to 1/8 in. (3.2 mm)
• Maximum cycle rate: 280 CPM
• Displacement per cycle: 0.17 gal (0.64 liters)
• Maximum suction lift: 16 ft (4.9 m) dry, 29 ft (8.8 m) wet
• Reliable, easy to maintain, suitable for continuous or intermittent duty

Applications:
Fluid transfer, oil and waste oil handling, fluid reclamation, and circulation systems in industrial, mining, and agricultural environments

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and warranty compliance.
• Ensure proper alignment of inlet and outlet connections (typically 1 in. NPT)
• Use recommended air pressure (20–100 psi for most models; check specific configuration)
• Install wall mount or bracket as needed for stability
• Follow manufacturer’s guidelines for diaphragm and seat replacement intervals
• Regularly inspect for leaks and wear
