The GRACO 648097 Husky 1050A-E is an air-operated double diaphragm pump designed for safe and efficient transfer of fluids, including oils and waste oils. It features an aluminum center section, Buna-N (BN) seats, balls, and diaphragm, and is equipped with a C1D1 flame proof motor for hazardous environments. This pump is intended for use in applications requiring reliable, stall-free, low-pulsation fluid transfer within GRACO equipment.

Key Features:

• Pneumatic (Air-Operated) Double Diaphragm Pump
• Husky 1050A-E
• Aluminum center section, Buna-N (BN) seats, balls, and diaphragm
• Up to 50 GPM (189 LPM) depending on configuration[2][5]
• Maximum fluid working pressure: 100–125 psi (7–8.6 bar, 0.7–0.86 MPa) depending on configuration[2][5]
• For use with oils, waste oils, and compatible fluids; not for use with highly corrosive or incompatible chemicals
• C1D1 Flame Proof Motor (for hazardous locations), UL-listed[1][3]
• Stall-free, low-pulsation air valve for smooth and rapid changeover
• Reliable and robust construction for demanding environments
• Easy maintenance with accessible components
• Suitable for handling solids up to 1/8 in (3.2 mm) in size
• Maximum cycle rate: 280 cycles per minute

Applications:
Ideal for transferring oils, waste oils, and similar fluids in industrial, mining, agricultural, and vehicle service environments. Suitable for use in hazardous locations requiring flame proof equipment.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment. Non-genuine parts may compromise reliability and safety, especially in hazardous environments.
• Ensure proper alignment and secure mounting of the pump
• Use appropriate fittings and hoses rated for the intended fluid and pressure
• Verify that the air supply is clean, dry, and within the specified pressure range (typically 20–100 psi, 1.4–7.0 bar)
• Check all seals and diaphragms for integrity before operation
• Follow all local and national safety regulations for installation in hazardous locations
• Regularly inspect diaphragms, seats, and seals for wear or damage
• Replace worn components with genuine GRACO parts
• Keep the pump and surrounding area clean to prevent contamination
• Monitor air supply quality and pressure
