The GRACO 648114 Husky 1050A-E is an air-operated double diaphragm pump designed for industrial applications. It features a TPE (thermoplastic elastomer) ball material and is intended for reliable, low-maintenance transfer of fluids, including oils and waste oils, in demanding environments.

Key Features:

• Air-Operated Double Diaphragm Pump
• 1050A-E
• Aluminum (body), TPE (diaphragms), Nitrile Rubber (seats)
• Up to 50 GPM (189 LPM) for aluminum models; some listings specify 38 GPM for certain configurations—check specific model for exact flow rate
• Maximum fluid working pressure: 100–125 psi (0.7–0.86 MPa, 7.0–8.6 bar) depending on configuration; maximum air pressure: 50–100 psi (0.35–0.7 MPa, 3.5–7.0 bar)
• Industrial fluids, oils, waste oils, compatible with fluids containing solids up to 1/8 in. (3.2 mm)
• UL listed (for certain models)
• Stall-free low pulsation air valve for smooth operation
• Bolted design for even sealing and easy maintenance
• TPE diaphragms for chemical resistance and durability
• Nitrile rubber seats for reliable sealing
• High reliability and long service life
• Suitable for continuous and intermittent duty cycles

Applications:
Transfer of industrial fluids, oils, and waste oils; fluid reclamation; suitable for use in mining, agriculture, manufacturing, and other industrial settings.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and warranty compliance.
• Ensure proper alignment of fluid and air connections
• Use recommended installation kits for wall or drum mounting
• Follow manufacturer guidelines for air pressure and flow settings
• Regularly inspect diaphragms and seals for wear
• Use only compatible fluids and avoid exceeding maximum solid size
• Periodically check and replace diaphragms and seals as needed
• Keep air supply clean and dry
• Inspect for leaks and ensure all fittings are secure
• Follow recommended cycle rates for continuous use (93–140 CPM) and circulation systems (20 CPM)
