The first ecological plastering machine on the world market.

Selected by a prestigious jury one of the most innovative products in the competition SAIE INNOVATION – towards zero impact.
The battery power supply makes it a product unique entirely redesigned and adapted to new markets with the advantage of comfort for the user and the environment.
Maximum satisfaction for the users
The S28 Urban Volta manufactured in compliance with European directives, is the answer to demands of professional plasterers.
The machine that you will be the vanguard in your field.
Powerful and versatile
The well-dimensioned power and the output control of the screw pump from zero to the maximum value allow the S28 Urban Volta pumping and spraying the traditional and special mortars.
Convenience, comfort, speed and savings
The movement of the screw pump from working position to cleaning position creates a discharge opening in the hopper and at same time causes the displacement of the screw feeder from the bottom of the hopper facilitating the cleaning of the hopper and the evacuation of the residual products.
Preserving the environment and your wallet
S28 Volta Urban is very economical: only about 1€* for a complete charge maintenance costs cheaper compared to the spraying machine with diesel engine.
Significant reduction of management and maintenance costs
The electric permanent magnet motors, compact and lightweight, are zero pollutants, require little maintenance and are very economical compared to the Diesel engine. The permanent magnet motor is controlled by an electronic controller which ensures a perfect control of the speed and torque of the motor.
Goodbye:
- engine oil and coolant changes
- belts
- filters
- flexible
- downtime for the execution
Battery pack with centralized filling system
The battery technology used is the “flooded/wet lead acid” which is proven, widespread and economical.
The estimated lifetime is about 1200 cycles with discharge of about 50% of the rated capacity.
More deeply discharged batteries, more they age rapidly.
To avoid premature wear we strongly advise you not to discharge the battery over 80%.
Water plays a crucial role in the functioning of the battery.
If the water level in the cells drops too low, the plates were then exposed to air. The active elements of the plates dry out and become brittle, which irreversibly damages the battery. The centralized filling system can simultaneously fill all the elements, if necessary.The discharge indicator integrated into the control panel as well as the integrated battery charger allow you to be independent on site.
Applications
- Spraying pre-mixed plaster
- Concrete spraying and fibre-reinforced mortar
- Injections of cement grouting under controlled pressure
- Pumping mortar and insulation materials
