• Maximum size pumpable solids: 0.09 in (2.5 mm)

Applications:
Industrial fluid transfer, including handling of chemicals, oils, detergents, resins, and wastewater treatment

Installation Notes:

• Ensures compatibility, reliability, and safety; prevents overpressurization and pump/hose rupture
• Install a fluid pressure relief valve at the pump outlet to prevent overpressurization (recommended part: GR238428)
• Ground the system as explained in the manual to prevent fire and explosion hazards
• Use conductive hoses and ensure dispense valve nozzle is in contact with the container for grounding
• Follow all safety instructions in the manual
