• Lightweight (approx. 6.5 lbs), easy to install and service
• Operates on as little as 20 psi (1.4 bar, 0.14 MPa) air supply
• Quiet operation (<85 dBa), with remote muffler capability
• Easy-to-service air valve and ball checks

Applications:
Industrial fluid transfer, including antifreeze, detergents, oils, grease, hydraulic and transmission fluids, cutting oil, water, wastewater, ink, resin, and polymers. Suitable for demanding environments such as manufacturing, mining, agriculture, and wastewater treatment.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety, and maintains warranty coverage.
• Ensure proper alignment and secure mounting of the pump
• Use appropriate fittings and hoses for the intended fluid and pressure
• Check air supply pressure (minimum 20 psi, maximum as per system requirements)
• Inspect diaphragms and ball checks regularly for wear and replace as needed
• Follow manufacturer guidelines for maintenance intervals and procedures
