The GRACO PR70 is a fixed ratio benchtop meter, mix, and dispense system designed for accurately metering, mixing, and dispensing two-component medium to low-viscosity materials. It is constructed primarily from stainless steel to minimize material incompatibility and is intended for use in industrial applications such as bonding, sealing, potting, gasketing, encapsulation, and syringe filling.

Key Features:

• Fixed ratio benchtop meter, mix, and dispense system
• PR70, 4.5AC, ADM, 2, BASE
• Stainless steel design with Chromex™ shafts, Severe Duty™ cylinders, and stainless steel fittings
• Handles most two-component materials; compatible with a variety of feed package options (polyethylene tanks, stainless steel tanks, off-board tanks, accumulators)
• Positive displacement pumps deliver ratio accuracy to ±1%
• Linear transducer monitors piston velocity for ratio assurance and reduced scrap/re-work
• Single stroke shot size ranges from 2 to 70 cc’s
• Ratio range from 1:1 to 24:1 (with PR70v for variable ratio)
• Long-lasting wear parts and easy-to-replace shaft seals
• Cast pump bodies for improved seal alignment
• Preventive maintenance counter for scheduled rebuilds
• Linear thrust bearings to maximize seal life and performance
• Electronic operator interface for digital shot entry and easy setup
• Built-in pot life timer and purge timer to minimize waste and downtime
• Modular design with quick board change-out for fast repairs
• Intuitive user interface with GRACO Control Architecture for diagnostics and control
