The GRACO 239131 is a surge suppressor designed for use with Husky 750 pumps. It features a manual adjustable design, PTFE bellows, and a stainless steel wetted bottom housing. Its primary function is to reduce pulsation and ensure consistent fluid delivery in industrial pumping applications.

Key Features:

• Surge suppressor
• 3/4 in, Husky 750
• Stainless steel wetted bottom housing, PTFE bellows
• Max fluid pressure: 0.8 MPa (approx. 116 psi)
• Husky 750 pumps
• Manual adjustable
• Reduces pulsation for consistent fluid delivery
• Durable stainless steel and PTFE construction for chemical resistance and longevity
• Easy to maintain and install

Applications:
Used in industrial fluid transfer and lubrication systems where consistent, pulsation-free flow is required. Suitable for mining, agriculture, and other heavy-duty applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and safety with GRACO equipment.
• Install the suppressor in the pump’s fluid line as recommended by GRACO.
• Ensure all connections are secure and leak-free.
• For air-operated pumps, use a tee in the pump’s air supply line to run an air line to the surge suppressor if required by the model.
• The tee must be located before any pump controller or instrumentation such as the filter, regulator, or pump control valve.
• Regularly inspect for leaks or wear.
• Replace bellows or seals as needed to maintain performance.
• Follow GRACO’s recommended maintenance schedule.
