The LAVINA L25S7 Triple Head Floor Grinder is a powerful and advanced grinding machine designed for professional concrete grinding, polishing and industrial surface preparation applications. Built for flooring contractors, polishing specialists and surface preparation professionals, this heavy-duty grinder delivers exceptional performance, durability and productivity across demanding commercial and industrial environments.
Powered by a robust 10hp / 7.5kW motor, the L25S7 provides powerful grinding performance with support for both single-phase and three-phase power configurations. Its triple-head planetary grinding system delivers smooth and balanced operation while covering large surface areas efficiently with a working width of 673mm.
The sealed and dust-proof grinding head features a completely redesigned chain-driven planetary drive system engineered for increased durability and reduced maintenance. Upgraded shafts, seals and bearings improve machine reliability while the stronger timing belt and lighter timing pulleys provide improved power transmission and longer service life.
The newly redesigned frame improves overall usability with faster and easier tool changes while the integrated weight system allows operators to quickly adjust grinding pressure using four different position settings. Rubber bushings at the head attachment points help reduce vibration during operation, improving operator comfort and machine stability.
Additional design improvements include heavy-duty rubber tyres, an upgraded handle with faster adjustment positions, a water tank with convenient storage compartment and adjustable LED lights for improved visibility in low-light working environments.
The machine supports both wet and dry grinding applications with gravity-fed water delivery from either the integrated tank or hose connection. Its Camlock E250 vacuum hose port allows for efficient dust extraction during dry grinding operations.
Whether used for concrete floor grinding, polishing, coating removal or industrial surface preparation, the LAVINA L25S7 delivers professional-grade performance, excellent durability and advanced engineering for demanding flooring projects.
