The GRACO 651935 Husky 1050S-E is a stainless steel, PTFE, and polysulfone air-operated double diaphragm pump designed for reliable, low-pulsation fluid transfer in demanding industrial environments. It is intended for use in applications requiring robust, chemical-resistant materials and smooth, efficient pumping of fluids with small solids.

Key Features:

• Air-Operated Double Diaphragm Pump
• 1050S-E
• Stainless Steel (SS), PTFE (PT), Polysulfone (PS), 6A (likely refers to a specific configuration or diaphragm material)
• Maximum free flow delivery: 50 gpm (189 lpm) for standard 1050 models; Husky 1050e-Series lists up to 42 gpm (158 lpm) for some configurations
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa) for standard 1050; some sources list 100 psi (7 bar, 700 kPa) for certain models
• Compatible with a wide range of fluids, including those with small solids up to 1/8 in (3.2 mm)
• UL listed; ATEX certification available for certain configurations (dependent on fluid temperature)
• Stall-free, low-pulsation air valve for smooth and rapid changeover
• Robust construction for chemical resistance and durability
• Ease of maintenance and repair
• Reliable performance in harsh environments
• Handles fluids with small solids

Applications:
Ideal for chemical transfer, industrial fluid handling, glycol circulation, and other applications requiring reliable, low-pulsation pumping of fluids with small solids

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment.
• Ensure proper alignment and secure mounting of the pump
• Use recommended fittings and hoses for inlet and outlet connections
• Check for leaks and proper air supply before operation
• Follow manufacturer guidelines for maintenance intervals and diaphragm inspection
• Regularly inspect diaphragms, balls, and seats for wear or damage
• Use only compatible fluids and avoid exceeding maximum pressure and temperature limits
• Consult the manual for specific installation and maintenance procedures
