Description
The GRACO 231618 President Hydra-Cat is a fixed ratio proportioning pump designed to accurately pump and proportion two-component materials. It features two positive displacement pumps for a 1:1 mix ratio and is constructed with wetted parts made from stainless steel, carbon steel, chrome plating, tungsten carbide, and Teflon. It is intended for use in industrial applications requiring precise mixing and dispensing of materials.

Applications:
Industrial mixing and dispensing of two-component materials such as resins and hardeners, suitable for manufacturing, maintenance, and repair operations.
Installation Notes:
- Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment.
- Label all pumps, hoses, and regulators to indicate resin or hardener side
- Turn on heaters (if used) and allow to warm up for 10 minutes before operation
- Open mixer manifold and trigger dispense valve before starting pumps
- Open feed pump air valves and adjust regulators to start pumps slowly
- Set air pressure to feed pumps at no more than 25% of proportional pressure at fluid outlets
- Monitor fluid outlet pressure gauges frequently during operation
- Open drain valves to prevent pressure buildup and place a grounded metal pail under drain valves
- Follow manufacturers instructions for installation and maintenance
- Regularly check and maintain wetted parts for wear and contamination
- Use only compatible fluids as specified by GRACO
