Mortar pump S8 Smart

Overview
BUNKER presents the S8 Smart, an autonomous plastering and mortar pumping machine designed for modern construction and renovation sites. Engineered to combine mobility, versatility and long component life, the S8 Smart addresses the needs of contractors who require on‑site autonomy and broad material compatibility.

Key features

• Dual power source with optional integrated petrol or diesel generator for complete autonomy on site
• Capable of powering auxiliary equipment (cement mixer, drill, halogen lamp) when fitted with generator
• Low rotational speed of the screw pump for extended component life and reduced maintenance costs
• Pumps materials with maximum aggregate size up to 10 mm and provides variable flow rate for versatile use
• Compact dimensions and moderate weight for easy transport and repositioning on site

Applications

• Self‑levelling floor screed
• Spraying of pre‑mixed or traditional plasters (interior/exterior)
• Concrete spraying
• Spraying fibre‑reinforced mortars
• Filling joints
• Injection of cement slurry

Included equipment and options
The S8 Smart is supplied with a comprehensive equipment package including compressor, vibrating screen, spraying kit, hose cleaning kit, manometer, remote control, operation and maintenance manual, and a toolkit with essential spare parts. Optional integrated petrol or diesel generator and an optional mixer are available.
