Frequently Asked Questions
The pump is compatible with a wide range of coatings including solvent-borne, water-borne, high solids paints, and adhesives. Stainless steel wetted parts ensure chemical resistance.
This pump is pneumatic, so it is not electrically powered. It can be integrated into electric-driven spray systems as part of a fluid supply line if air is available for operation.
Check the machine's OEM manual for pump ratio, inlet/outlet thread size, and pressure requirements. This ensures compatibility with your existing system.
