Frequently asked questions.
Answers to the most common questions about Dai Prà machines.
Can I buy a single machine, or only complete plants?
Both. Grout pumps, mixers, agitators, big bag silos and accessories are also sold individually. They can complete a plant you already have on site or form a new plant together with other Dai Prà machines.
What materials can I pump with Dai Prà machines?
Cement and bentonite mixes, including those with fine-grained sand, silica or lime, as well as resins, polymer suspensions and other cement additives. The maximum particle size depends on the pump and goes up to 4 mm.
What are the advantages of Dai Prà machines?
Dai Prà is a manufacturer that designs and builds all its machines in-house. This lets us oversee every stage of development directly, continually improving mechanical and software solutions thanks to customer feedback, field experience and ongoing research into new technologies.
- In-house design and manufacturing: direct control of every production stage lets us continually improve our machines and develop customised solutions for each customer's specific needs.
- Robust and built to last: particular care goes into the quality of machining and into the pumping units, designed for high wear resistance and reliability even in the toughest working conditions.
- Easy to use and maintain: drawing on direct industry experience and a clear understanding of site needs, Dai Prà puts the operator and site manager at the centre of the design, building machines that are intuitive, practical to use and easy to maintain.
