The GRACO 648094 Husky 1050A-E is an air-operated double diaphragm pump featuring a stainless steel (SS) and plastic (PS) construction. It is designed for reliable, efficient transfer of fluids such as oils and waste oils, and is commonly used in industrial fluid handling and lubrication systems.

Key Features:

• Pneumatic (air-operated) double diaphragm pump
• Husky 1050A-E, SS/SS/PS/4D
• Stainless steel (SS) and plastic (PS) wetted parts, with specific configurations for center section, seats, and balls
• Up to 50 GPM (189 LPM) for metal versions; actual for this specific configuration may vary, but typically in this range[3][5]
• Maximum fluid working pressure: 70 psi (0.48 MPa) for this specific part number; other Husky 1050 models may handle up to 100–125 psi depending on configuration[3][4][5]
• Designed for use with oils, waste oils, and compatible with various industrial fluids; not for use with highly corrosive or incompatible chemicals unless specified
• UL listed for certain configurations; check specific part for full certification details[2][5]
• Stall-free low pulsation air valve for smooth operation
• Reliable, robust construction for industrial environments
• Easy maintenance with accessible diaphragm and valve assemblies
• Capable of handling solids up to 1/8 in. (3.2 mm) in size
• Suitable for continuous or intermittent duty cycles

Applications:
Industrial fluid transfer, lubrication systems, waste oil handling, and general-purpose pumping in mining, agriculture, and manufacturing environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise reliability and void warranties.
• Ensure proper alignment and secure mounting to prevent vibration and leaks
• Use appropriate fittings and hoses rated for the intended fluid and pressure
• Follow manufacturer guidelines for air supply and pressure settings
• Regularly inspect diaphragms, valves, and seals for wear and replace as needed
• Lubricate moving parts as recommended in the manual
• Perform routine inspections and maintenance as outlined in the GRACO manual
• Replace diaphragms and seals at recommended intervals
• Keep air supply clean and dry to prevent internal corrosion
• Monitor for leaks and unusual noises during operation
