The GRACO Husky 1050S-E is a stainless steel air-operated double diaphragm pump designed for reliable transfer of fluids, including those with suspended solids, in industrial and maintenance applications. It is constructed primarily from stainless steel and engineered for durability and chemical resistance.

Key Features:

• Pneumatic Diaphragm Pump
• 1050S-E
• Stainless Steel (SS/SS/PO/5A indicates stainless steel wetted parts, stainless steel air valve, polypropylene diaphragms, and 5A elastomer seats)
• Maximum free flow delivery: 50 gpm (189 lpm)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa) for metal models; some sources list 100 psi (7 bar, 0.7 MPa) for certain configurations
• Compatible with a wide range of fluids, including those with suspended solids up to 1/8 in (3.2 mm)
• UL listed
• Stall-free low pulsation air valve for smooth and rapid changeover
• Bolted design for even sealing and easy maintenance
• Reliable operation with minimal maintenance required
• Suitable for continuous duty cycles

Applications:
Ideal for transferring fluids in industrial, mining, agricultural, and maintenance environments where chemical resistance and reliability are required. Suitable for handling fluids with suspended solids.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump.
• Ensure proper alignment and secure mounting of the pump
• Use appropriate fittings and hoses rated for the intended pressure and fluid
• Follow manufacturer guidelines for air supply and exhaust connections
• Regularly inspect diaphragms and seals for wear and replace as needed
• Perform routine checks on diaphragms, seals, and air valve
• Keep air supply clean and dry to prevent internal damage
• Lubricate moving parts as recommended by GRACO
