The GRACO Husky 1050S-E is an air-operated double diaphragm pump constructed primarily from stainless steel, with PTFE (polytetrafluoroethylene) and PO (polypropylene) components, and features a 4C configuration. It is designed for reliable, low-maintenance transfer of a wide range of fluids, including those with abrasive or corrosive properties, in industrial and maintenance applications.

Key Features:

• Air-Operated Double Diaphragm Pump
• 1050S-E, 1" connection
• Stainless steel, PTFE, polypropylene (PO), 4C configuration
• 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 general use—confirm for specific configuration
• Compatible with a wide range of fluids, including corrosive and abrasive liquids
• UL listed
• Stall-free, low pulsation air valve for smooth and rapid changeover
• Bolted design for even sealing and easy maintenance
• Reliable, robust construction for heavy-duty use
• Handles solids up to 1/8 in (3.2 mm) in size
• Maximum suction lift: 16 ft (4.9 m) dry, 29 ft (8.8 m) wet
• Maximum pump speed: 280 cpm
• Displacement per cycle: 0.17 gal (0.64 liters)

Applications:
Ideal for transferring fluids in industrial, mining, agricultural, and maintenance environments, especially where reliability and resistance to corrosion or abrasion are required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump and connected equipment.
• Ensure proper alignment and secure mounting of the pump
• Use appropriate fittings and hoses rated for the intended pressure and fluid
• Check for leaks after installation and during initial operation
• Follow manufacturer guidelines for air supply and fluid compatibility
• Regularly inspect diaphragms, seals, and valves for wear and replace as needed
