PR70 Benchtop Metering Systems
Benchtop piston pump systems for precisely dispensing 2K fluids
The Graco PR70 is a fixed ratio system which is specifically created to measure, mix and dispense to highly accurate specifications medium-to-low viscosity materials for potting, gasketing, sealing encapsulation, and syringe filling.
The Graco PR70 contains all the key features you require in a compact, modular design, for:
- Medium to low viscosity materials
- Exceptional performance with materials form 1:1 to 24:1
- MD2 valve high pressure accuracy with multiple seat styles and adjustable snuffback for clean, precise dispensing
- Linear transducer monitors piston velocity to provide ratio assurance, and reduce scrap and re-work
- Proven ratio accuracy. Positive-displacement and multiple tube sizes to pinpoint specific target ratios delivering ratio accuracy to +/- 1%
Other benefits of the PR70 include:
- Stainless steel design reduces the chance of a material incompatibility
- Long-lasting wear parts mean lower cost of ownership
- Shaft seals designed for extended life and easy replacement
- Preventive maintenance counter to plan system rebuilds around your production schedule
- Linear thrust bearings eliminate side loading to maximize seal life and performance
