Frequently Asked Questions

A 3:1 ratio means the pump delivers three times the fluid pressure compared to the supplied air pressure, allowing efficient material transfer with controlled output.

This pump is best suited for low- to medium-viscosity fluids such as paints, coatings, and compatible industrial liquids. For very high-viscosity materials, higher-ratio pumps are typically recommended.

Yes, the pump is commonly installed in drum-mounted or tank-mounted configurations as part of a complete material supply system.
