PR70-MIXING AND DISPENSING SYSTEM

PR70

The Graco PR70 offers high precision and accuracy for a wide range of applications such as metering, mixing and dosing systems, bonding, sealing, potting and encapsulation. Stainless steel design reduces the possibility of material incompatibility. Positive working pumps provide precise operation with an accuracy of ± 1%. Linear sensor monitors piston speed to ensure safe proportioning, thus avoiding waste and rework. There are dosage amounts from 2 to 70 cc. The ratio range is changed by variable drive from 1: 1 to 24: 1. Electronic controls allow digital dosage input in grams. Built-in, easy-to-install clean / drain timer keeps the system running, ensuring continued production. Long-lasting wear parts reduce the cost of ownership. Thanks to the maintenance counter, new system installations can be easily planned within the scope of your production program. Shaft seals are designed for long life and easy replacement.
