The GRACO 563326 is a high pressure blowout switch designed for use with oil and grease in GRACO lubrication systems. It functions as a safety device to protect reservoirs from overpressure by triggering a switch when a preset pressure is exceeded, ensuring safe operation of the equipment.

Key Features:

• High Pressure Blowout Switch
• For 5.68 liter (12 pt.) and 9.46 liter (20 pt.) or 5.44 kg (12 lb.) and 9.06 kg (20 lb.) reservoirs
• High pressure (specific rating not listed in available sources, but typically associated with Modu-Flo systems up to 1450 PSI for similar switches)
• Oil, grease; compatible with 12 and 20 pt/lb reservoirs
• Single-pole, double-throw type (for similar Modu-Flo switches)
• Rated for high pressure applications
• Reliable safety mechanism for reservoir protection
• Ease of maintenance (as a replaceable safety component)

Applications:
Used in GRACO lubrication systems for industrial, mining, and agricultural equipment to protect reservoirs from overpressure during operation.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and safety of the lubrication system.
• Install according to GRACO equipment manual instructions
• Ensure proper alignment and secure mounting
• Regularly inspect for wear or damage and replace as needed
