GRACO 223954 2:1 Ratio Stainless Steel Transfer Pump

The 223954 is a 2:1 ratio stainless steel air-operated piston transfer pump designed for reliable transfer of industrial fluids from 5 gallon containers.

Featuring stainless steel construction and PTFE packed sealing components, this pump provides durable performance for applications requiring chemical compatibility and consistent material delivery.

Unlike diaphragm pumps, the piston transfer design provides higher pressure output for transferring medium to high viscosity materials such as sealants, adhesives and coatings.

The 2:1 air-to-fluid ratio delivers balanced pressure amplification, making it suitable for supply and transfer applications where stable material flow is required.
