The GRACO 648018 Husky 1050A-E is an air-operated double diaphragm pump designed for industrial applications. It features a robust aluminum construction and is intended for reliable transfer of fluids such as oils and waste oils, especially in demanding environments. The pump is known for its smooth, low-pulsation operation and is suitable for use with fluids containing small solids.

Key Features:

• Pneumatic (Air-Operated) Diaphragm Pump
• Husky 1050A-E
• Aluminum body, Santoprene ball material, Buna-N seat material
• Maximum free flow delivery: 50 GPM (189 LPM) (varies by configuration; some sources list 38 GPM for specific models)
• Maximum fluid working pressure: 100–125 psi (0.7–0.86 MPa, 7.0–8.6 bar) depending on configuration; some models specify 50 psi (0.35 MPa) for fuel dispense
• For use with oils, waste oils, and compatible with fluids containing solids up to 1/8 in. (3.2 mm)
• UL listed; ATEX certified for certain models (dependent on configuration and region)
• Stall-free, low-pulsation air valve for smooth operation
• Robust aluminum construction for durability
• Easy maintenance and serviceability
• Reliable performance in harsh environments
• Suitable for continuous or intermittent duty cycles

Applications:
Industrial fluid transfer, oil and waste oil handling, fuel dispensing, and applications requiring reliable pumping of fluids with small solids.

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 and secure mounting of the pump
• Use recommended air pressure (20–100 psi, 0.14–0.7 MPa) for safe operation
• Connect fluid inlet and outlet using 1 in. NPT fittings as specified
• Follow manufacturer guidelines for maintenance intervals and inspections
• Check for leaks and proper diaphragm function after installation
• Regularly inspect diaphragms and seals for wear
• Replace worn or damaged parts with genuine GRACO components
• Keep air supply clean and dry to prevent internal damage
• Monitor cycle rates and fluid pressures to avoid overloading the pump
