The GRACO 648150 is a Husky 1050A-E air-operated double diaphragm pump, constructed with aluminum and acetal components, designed for industrial fluid transfer applications. It is engineered for reliable, efficient, and robust performance in demanding environments.

Key Features:

• Air-operated double diaphragm pump
• Husky 1050A-E, 1 in. inlet/outlet (NPT)
• Aluminum body, acetal balls, TPE seats and diaphragms
• Up to 50 gpm (189 lpm) maximum free flow delivery[1][5]
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa) for metal models; for 1050A-E, typical maximum fluid pressure is 50–70 psi (3.5–4.8 bar) depending on configuration[3][4]
• Industrial fluids, oils, waste oils, compatible with various industrial equipment[4]
• Stall-free low pulsation air valve for smooth operation
• Up to 80% more efficient than standard air-operated diaphragm pumps (for electric models; air-operated models are highly efficient)
• Handles solids up to 1/8 in. (3.2 mm)
• Maximum suction lift: 16 ft (4.9 m) dry, 29 ft (8.8 m) wet
• Easy maintenance and robust construction

Applications:
Industrial fluid transfer, oil and waste oil handling, mining, agriculture, and other demanding environments requiring reliable, efficient pumping of fluids with solids[4]

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
• Use appropriate thread sealant for NPT connections
• Check air supply for correct pressure and cleanliness
• Follow manufacturer’s torque specifications for assembly
• Regularly inspect diaphragms, balls, and seats for wear
• Periodically check and replace diaphragms and seals as needed
• Monitor for leaks and unusual noise
• Keep air supply clean and dry
• Lubricate moving parts as recommended by GRACO
