Lightweight pump by Sto Corp.

The Sto M-8 Spray Pump reduces the amount of labor required to hand-apply basecoats, adhesives primers, coatings and finishes. Additionally, the Sto M-8 contains a technologically advanced and patented peristaltic pump. The advantage: rhythmic, wavelike motion of the pressure disc allows for the pumping of low- and high-viscosity materials. Its lightweight and portable frame can be moved quickly and used on interior and exterior applications.
