The GRACO Husky 1050 Polypropylene Pump is an air-operated double diaphragm pump constructed primarily from polypropylene, with polypropylene seats, Buna-N balls, and a Buna-N diaphragm. It is designed for reliable transfer of fluids such as water, antifreeze, and fuel in industrial and vehicle service applications.

Key Features:

• Air-Operated Double Diaphragm Pump
• Husky 1050, 1 inch (nominal size)
• Polypropylene center section, end flange, and seats; Buna-N balls and diaphragm
• Maximum free-flow delivery: 189 L/min (50 gpm)
• Maximum fluid working pressure: 100 psi (7 bar, 700 kPa) for plastic models (varies by material; metal models may be higher)
• Suitable for water, antifreeze, fuel, and other compatible fluids; not for use with incompatible chemicals
• UL listed
• Stall-free low pulsation air valve for smooth operation
• Longer diaphragm life (up to 5x longer in some models)
• Pulse count feature for monitoring cycles
• Easy maintenance and reliable performance
• Handles solids up to 1/8 inch (3.2 mm) in size

Applications:
Industrial fluid transfer, vehicle service (fuel, antifreeze, water), and other applications requiring robust, chemical-resistant pumping solutions.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment.
• Ensure proper alignment and secure mounting of the pump
• Use appropriate fittings and hoses rated for the intended fluid and pressure
• Follow manufacturer guidelines for air supply and exhaust
• Regularly inspect and maintain diaphragms, balls, and seals for wear
