These pumps are characterized by a type of operation that involves the gradual compression by means of rollers of a flexible tube, which induces a continuous transfer of product.
The main features of this pump include a homogeneous transfer that keeps the product intact, a high self-priming capacity, no contact between the product to transfer and the mechanical drive components, accurate product dosage thanks to the presence of an inverter that enables an exact adjustment of the flow rate: the inverter is supplied as a standard accessory on all the models.
This type of pump is manufactured from the model PPD 60 (6-150 hl/h of liquid) to the model PPD 120 (95-1000 hl/h of liquid).
All the models can be fitted with the radio remote controls and a hopper with a feeding screw.
