The GRACO 648108 Husky 1050A-E is an industrial-grade, air-operated double diaphragm pump designed for reliable transfer of fluids such as oil and waste oil. It features an aluminum construction for durability and is engineered for smooth, low-pulsation operation with a stall-free air valve.

Key Features:

• Pneumatic Diaphragm Pump
• Husky 1050A-E
• Aluminum body, Santoprene ball material, Buna-N seat material
• Up to 50 GPM (189 L/min) depending on configuration
• Maximum fluid working pressure: 100–125 psi (0.7–0.86 MPa, 7–8.6 bar) depending on configuration; Maximum air pressure: 50–100 psi (0.35–0.7 MPa, 3.5–7 bar) depending on configuration
• For use with oil, waste oil, and compatible industrial fluids
• UL listed
• Stall-free low pulsation air valve for smooth operation
• High reliability and ease of maintenance
• Handles solids up to 1/8 in. (3.2 mm)
• TPE diaphragms and nitrile rubber seats for chemical resistance
• Air consumption: 25 SCFM at 50–70 psi
• Maximum cycle rate: 280 CPM

Applications:
Ideal for fluid reclamation, oil transfer, waste oil handling, and general industrial fluid transfer applications. Suitable for use in mining, agriculture, and other heavy-duty environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment.
• Ensure proper alignment of fluid and air connections (1 in. NPT for fluid, 1/2 in. NPT for air)
• Mount securely using provided wall brackets or suitable supports
• Check all seals and diaphragms before operation
• Follow recommended cycle rates for continuous use (93–140 CPM) and circulation systems (20 CPM)
• Regularly inspect and maintain diaphragms and seats for longevity
