The GRACO Husky 1050S-E is an air-operated double diaphragm pump designed for reliable fluid transfer. It is constructed with a metal body (commonly aluminum, stainless steel, or Hastelloy options) and features a TPE (Hytrel) seat material. This pump is intended for use in applications requiring robust, stall-free, low-pulsation fluid transfer, such as fuel, chemicals, or other compatible liquids within GRACO equipment.

• Suitable for continuous duty cycles

Applications:
Fuel transfer, chemical transfer, and other industrial fluid handling applications where reliable, low-pulsation pumping is required.

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 of the pump
• Use recommended air supply and pressure (maximum air pressure: 50 psi, 0.35 MPa)
• Check all connections for leaks before operation
• Follow manufacturer guidelines for fluid compatibility and temperature limits (maximum operating temperature: 150°F/66°C)
• Regularly inspect diaphragms and seals for wear and replace as needed
