• Maximum fluid working pressure: 100 psi (7 bar, 0.7 MPa)
• Compatible with a wide range of industrial fluids; suitable for remote operation
• No mechanical seals, reducing risk of leaks and failures
• Runs quietly (typical sound level at 70 psi air: 74 dBa)
• Easy-to-use remote muffler
• Handles solids up to 0.09 in (2.5 mm)
• Maximum suction lift: 15 ft (4.5 m) dry
• Maximum ambient operating temperature: 180°F (82°C)
• Maximum pump speed: 400 cpm
• Displacement per cycle: 0.04 gallon (0.15 liter)

Applications:
Ideal for transferring a variety of fluids in industrial, mining, agricultural, and maintenance environments. Suitable for applications requiring reliable, leak-free operation and the ability to handle small solids.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure proper alignment and secure mounting of the pump
• Use recommended air pressure (30–100 psi, 2.1–7 bar)
• Install air regulator and filter with gauge for optimal operation
• Check for correct porting (center or end) and connection type (Bsp or Npt)
• Regularly inspect diaphragms and seals for wear and replace as needed
• Follow manufacturer’s recommended maintenance schedule
• Use only genuine replacement parts for repairs
• Keep air supply clean and dry to prevent contamination
• Monitor for unusual noise or reduced performance as indicators of wear
