The KEISERtools SP650 Dry Mix Spray Plaster Machine is engineered for high‑efficiency plastering across large construction projects, delivering consistent performance, robust power, and exceptional material handling. Designed specifically for dry‑mix applications, the SP650 ensures precise blending, controlled water dosing, and uniform spraying, making it an ideal choice for contractors seeking speed, reliability, and superior surface finishes.

Advanced Dry‑Mix Technology

The SP650 is built to process dry‑bagged plaster materials, automatically combining them with water through its integrated water pump system. This ensures a consistent, homogeneous mixture with optimal workability. The machine’s design eliminates manual mixing, reduces material waste, and guarantees a stable flow for continuous spraying.

High‑Performance Power System

Equipped with a 5.5 kW motor and a 1 kW air compressor, the SP650 delivers strong, steady spraying performance. The 380V / 50Hz power configuration supports industrial workloads and ensures reliable operation during long working cycles. The built‑in air compressor provides the necessary air volume and pressure to achieve a smooth, even spray pattern.

Efficient Material Conveying

With a conveying capacity of 35 L/min, the SP650 maintains a consistent material flow suitable for large‑scale plastering tasks. Its 50 bar output pressure ensures uniform application, even with thicker or more demanding dry‑mix materials.

Extended Working Range

The SP650 is designed to cover wide areas and multi‑story structures with ease:

• Horizontal conveying distance: up to 60 meters
• Vertical conveying distance: up to 50 meters

This extended reach minimizes machine repositioning and boosts overall productivity.

Versatile Material Handling

Supporting materials with a maximum particle size of 6 mm, the SP650 accommodates a wide range of dry‑mix plasters and mortars. Its 115 L stirrer capacity ensures continuous mixing and stable material consistency throughout operation.

Ergonomic and Practical Design

A 900 mm filling height allows easy loading of dry‑mix bags, reducing operator fatigue. Despite its powerful capabilities, the SP650 maintains a compact and maneuverable structure:

• Weight: 220 kg

Its balanced design ensures stability during operation while remaining easy to move around job sites.
