The Piovan range of single phase hopper loaders allows for automatic granule conveying to drying hoppers, volumetric and gravimetric blenders, and processing machines.
The S single phase hopper loaders incorporate the vacuum motor. They can convey up to 200 kg/h of material and the distance can reach 20 m. The S series loaders are equipped with a new keypad control which includes a powerful microprocessor.
The display and keyboard grant a simple and quick access to all the functions. The RS485 serial communication port (modbus protocol) is included as standard.

The high reliability of the Piovan single phase loaders is ensured by two devices included in the standard configuration, considerably increasing the vacuum pump’s life:
• Soft start function, which reduces the wear out of the brushes and the risk of damaging the motor.
• Warning signals indicating the necessity to replace the brushes.

• 1 kW double step vacuum motor
• Paper or fabric filter
• Automatic filter cleaning device (by means of compressed air)
