Applications:
Ideal for industrial fluid transfer applications, including water, antifreeze, and fuel transfer. Suitable for environments requiring hazardous location certification (C1D1). Can replace progressive cavity, peristaltic, and rotary lobe pumps in certain applications for improved reliability and reduced maintenance.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise reliability and safety, especially in hazardous environments.
• Ensure all connections are secure and compatible with the pump’s porting (1 in NPT for aluminum/stainless steel models)
• Verify that the installation environment meets the ambient temperature range (0°C to 40°C) to prevent damage to plastic components
• Follow all local and national electrical codes for hazardous location installations
• Regularly inspect diaphragms, balls, and seats for wear and replace as needed to maintain performance
• Consult the operation manual (334188) and repair manual (334189) for detailed installation and maintenance procedures
