The Graco 648008 is an air-operated double diaphragm pump designed for industrial applications. It features an aluminum construction and is intended for reliable, efficient transfer of fluids, including those with small solids, within GRACO equipment and compatible systems.

Key Features:

• Air-Operated Double Diaphragm Pump
• 1050A-E
• Aluminum (body), Acetal (ball material), Buna-N (seat material)
• Up to 50 GPM (189 LPM) for standard Husky 1050 models; some listings specify 38 GPM for specific configurations—confirm with exact model variant
• Maximum fluid working pressure: 100–125 psi (0.7–0.86 MPa, 7–8.6 bar) depending on configuration; some listings specify 50 psi (0.35 MPa) for certain uses—check application requirements
• Industrial fluids, including oils and waste oils; compatible with systems requiring 1 in. NPT fluid connections
• UL listed (for some configurations)
• Stall-free, low pulsation air valve for smooth operation
• Handles solids up to 1/8 in. (3.2 mm)
• Reliable, robust construction for continuous industrial use
• Easy maintenance with accessible components

Applications:
Industrial fluid transfer, oil and waste oil handling, fluid reclamation, and circulation systems in mining, agriculture, and other heavy-duty environments.

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 fluid and air connections (1 in. NPT for fluid, as specified)
• Use recommended installation kits for wall mounting or drum-style adapters if required
• Follow manufacturer’s guidelines for air pressure (typically 20–100 psi, 0.14–0.7 MPa)
• Regularly inspect diaphragms and seats for wear and replace as needed
• Maintain recommended cycle rates for continuous use (93–140 CPM) and circulation systems (20 CPM)
