The GRACO Husky 1050A is an air-operated double diaphragm pump constructed primarily from aluminum, designed for reliable transfer of oils and waste oils. It is intended for use in fluid handling and reclamation applications within GRACO equipment and systems.

Key Features:

• Pneumatic Diaphragm Pump
• Husky 1050A
• Aluminum body, TPE diaphragms, Nitrile Rubber seats
• Maximum flow rate: 38–50 GPM (depending on configuration and pressure)
• Maximum fluid working pressure: 50–125 psi (depending on configuration; 50 psi for UL-listed models, 100–125 psi for standard models)
• For use with oil and waste oil; compatible with fluids containing solids up to 1/8 in. (3.2 mm)
• UL-listed (for certain models)
• Stall-free low pulsation air valve for smooth and rapid changeover
• Reliable, robust construction for continuous duty
• Easy maintenance with accessible components
• Handles fluids with solids up to 1/8 in. (3.2 mm)
• Maximum cycle rate: 280 CPM
• Maximum suction lift: 16 ft (4.9 m) dry, 29 ft (8.8 m) wet

Applications:
Used for fluid reclamation, oil transfer, and waste oil handling in industrial, mining, agricultural, and vehicle service environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with GRACO equipment.
• Ensure proper alignment of inlet and outlet connections (typically 1 in. NPT)
• Use recommended air pressure (20–100 psi for standard models, up to 50 psi for UL-listed models)
• Check for leaks and secure all fittings before operation
• Follow manufacturer’s guidelines for cycle rate and continuous use recommendations
• Regularly inspect diaphragms and seals for wear
• Replace worn components with genuine GRACO parts
• Keep pump clean and free from debris
• Monitor air consumption and fluid flow for signs of wear or blockage
