The GRACO Husky 1050A is a stainless steel air-operated double diaphragm pump designed for reliable transfer of fluids, including oils and waste oils, in industrial and maintenance applications. Its robust construction ensures compatibility with a wide range of fluids and environments.

Key Features:

• Pneumatic (Air-Operated) Double Diaphragm Pump
• Husky 1050A, 1" NPT connections
• Stainless steel fluid section, stainless steel wetted parts, polypropylene diaphragms (PO), Buna-N seats (4B)
• Maximum free flow delivery: 50 GPM (189 LPM) (varies by configuration; some listings specify 38 GPM for certain models)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa) for metal pumps; some configurations (e.g., UL-listed for fuel) specify 50 psi (0.35 MPa, 3.5 bar)
• For use with oil, waste oil, and compatible with a wide range of industrial fluids; handles solids up to 1/8 in. (3.2 mm)
• UL-listed for certain models (e.g., fuel dispense)
• Stall-free low pulsation air valve for smooth operation
• Bolted design for even sealing and easy maintenance
• Reliable, robust construction for continuous duty
• Handles abrasive and viscous fluids
• Easy to disassemble and maintain

Applications:
Industrial fluid transfer, oil and waste oil handling, fluid reclamation, circulation systems, and general maintenance in mining, agriculture, and manufacturing environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and warranty compliance.
• Ensure proper alignment of inlet and outlet connections (1" NPT)
• Use recommended air pressure (typically 20–100 psi, 0.14–0.7 MPa)
• Check for leaks and proper seating of diaphragms and seals
• Follow manufacturer’s guidelines for cycle rate and continuous use
• Regularly inspect and maintain diaphragms and seals for longevity
