The Husky 1050 is an air-operated double diaphragm pump designed for industrial transfer of water, antifreeze, and fuel. The specified configuration uses polypropylene for certain components, but the core pump is typically constructed with aluminum fluid sections and TPE (Hytrel) seats. The part referenced (650153) appears to be a variant with a 240V compressor, BLDC motor, center flange, aluminum center section, and Buna-N seats, balls, and diaphragms, though this exact configuration is not detailed in standard GRACO listings. The pump is intended for reliable, efficient fluid transfer in demanding environments.

Key Features:

• Pneumatic Diaphragm Pump
• Husky 1050 Series, 1 in. AL/TPE
• Aluminum fluid section (standard), polypropylene or Buna-N components in some variants; Buna-N seats, balls, and diaphragms in specified configuration

Applications:
Industrial transfer of water, antifreeze, fuel, and oil; suitable for vehicle service, mining, agriculture, and general industrial fluid handling

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 recommended fittings and hoses for the intended fluid
• Check for leaks and proper air supply before operation
• Follow manufacturer guidelines for maintenance intervals and part replacement
• Regularly inspect diaphragms, seats, and balls for wear
• Use only compatible fluids and materials as specified by GRACO
• Keep air supply clean and dry to prevent contamination
