The Wagner SuperFinish 21 Pro (versions 2437311 & 2437312) is a robust device that offers all the advantages of a compact diaphragm pump. For small and medium-sized projects, the Spraypack is perfect for spraying varnishes, primers, lacquers, impregnations and glycerine lacquers. The Wagner SF 21 Pro can also be used to disperse thin or diluted paints with additional accessories (version 2437311).
As with all Wagner diaphragm pumps, the inlet and outlet valves can be replaced quickly and easily on site. As a result, downtime is minimal while service costs remain low. The compact design of the SF 21 Pro is also an advantage, as it requires little storage space for transport.
