Precision Dispense

For the filtration industry, the Graco PR70 accurately mixes and dispenses a two-part potting compound to seal hollow fibers in biomedical filters. The PR70 is a compact, reliable benchtop fixed and variable ratio meter, mix and dispense system that accurately meters, mixes and dispenses two-component medium to high-viscosity materials for a broad range of applications including bonding, sealing, potting, gasketing, encapsulation and syringe filling. Standard features include electric controls, digital shot entry, gel timer, purge and preventative maintenance counters.

Posi- Ratio by Positive Displacement

The Graco PR70 uses positive displacement pumps to deliver unmatched consistency with ratio accuracy to ± 1% and 2X increase in Mean Time Before Failure (MTBF). Multiple configurations support a wide variety of applications with a ratio range from 1:1 to 24:1 with variable drive and shot sizes from 2 to 70m cc’s. Stainless steel design reduces the chance of a material incompatibility while long-lasting wear parts mean lower cost of ownership. Learn more about the PR70.
