National GP 7 Grinder & Polisher
The GP series prepares concrete floors for topical coatings, overlayments, and adhesive floor coverings. It will efficiently polish floors to a high-gloss shine.
The GP series prepares concrete floors for topical coatings, overlayments, and adhesive floor coverings. It will efficiently polish floors to a high-gloss shine. Equipped with a gear-to-gear calibrated counter-rotational tooling matrix, the GP7’s counterbalanced, centrifugal-centered design does not pull side-to-side, lessening operator fatigue and increasing productivity.
A. LCD (liquid crystal display) control box includes variable speed and soft start features minimize blown circuit breakers; forward and reverse functionality results in cleaner consumables and more consistent tooling wear
B. 11-gallon, onboard water tank; water dosing system supports wet grinding slurry applications such as hardtroweled concrete, granite floors, and marble surfaces
C. Four removable side weights for additional head pressures; positioning weights into handle pockets reduces head pressure for easy mobility and allows the operator to adjust the weight from left to right
D. Adjustable powder-coated mild steel shroud; can be easily raised during wet-grinding applications or higher grit polishing
E. Additional transport wheels
F. Dual 3-inch vacuum ports
G. Each counter-rotating tooling holder is mounted on a Morflex coupler for easy maintenance and allows the tooling to follow surface contours for polishing or creating a uniform scratch pattern for coating applications
