The GRACO Husky 1050A-E is a pneumatic diaphragm pump designed for reliable fluid transfer in industrial applications. This model features a stainless steel (SS) construction for enhanced durability and chemical resistance, and is intended for use with a variety of fluids, including oils and waste oils, within GRACO equipment. The pump is suitable for demanding environments such as mining, agriculture, and manufacturing.

Key Features:

• Pneumatic Diaphragm Pump
• 1050A-E, SS/CW/CO/4A
• Stainless Steel (SS), with other wetted parts as specified by configuration
• Up to 50 GPM (189 LPM) for standard Husky 1050 models; specific flow rate for this configuration may vary but is typically in this range[1][4]
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa) for Husky 1050 metal pumps; some configurations may have lower ratings (e.g., 100 psi for certain packages)[1][4]
• Designed for use with oils, waste oils, and compatible with a wide range of industrial fluids[2]
• UL listed; ATEX certification available for certain models (dependent on configuration and region)[2][5]
• Stall-free, low pulsation air valve for smooth operation
• Modular air valve for easy maintenance
• Handles solids up to 1/8 in (3.2 mm)
• Reliable, robust construction for heavy-duty use
• Easy to maintain and service

Applications:
Ideal for fluid transfer, oil dispensing, waste oil handling, and general industrial pumping applications. Suitable for use in mining, agriculture, manufacturing, and maintenance operations.

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 of inlet and outlet connections (typically 1 in. NPT)
• Use recommended air pressure (20–100 psi, depending on configuration)
• Install pressure relief valve if not already included
• Follow local safety and regulatory requirements
• Regularly inspect diaphragms and seals for wear
• Periodically check and replace diaphragms and seals as needed
• Lubricate moving parts according to manufacturer guidelines
• Inspect for leaks and ensure all connections are secure
• Clean pump internals if handling abrasive or contaminated fluids
