Wagner’s SF23 Pro diaphragm pump is a great choice when it comes to handling a wide variety of materials. With its patented QLS (quality long stroke) technology it provides superior performance eliminating pulsation for smooth application. The longer stroke of the diaphragm allows the application of a wide range of materials, from thin stains and lacquers to higher-viscosity coatings. The low stroke frequency puts less stress on internal components, significantly extending the service life and keeping maintenance costs low. The valves are made from wear-resistant carbide and the diaphragm is made of solvent resistant polyamide. Diaphragm pumps use fewer parts, are longer wearing & can be serviced using a quick-change valve set, whereas piston pumps are required to be taken to a service centre for service. It’s a versatile and robust sprayer that’s the perfect all-rounder for multiple application types. Compact in design, it's the smallest in its class, thus mobile and lightweight whilst robust for demanding construction site use.
