3P PRINZ is an Italian manufacturer of positive displacement pumps and packaged systems for fluid transfer, recognised for combining proprietary engineering, configuration flexibility and a strong orientation towards demanding applications. Within its offering, hollow disc pumps represent one of its most distinctive technologies, particularly valued when the process demands stable, gentle and reliable pumping even with difficult products.
The 3P PRINZ hollow disc pump technology is based on a positive displacement principle that conveys the fluid with a virtually pulse-free flow rate, at low rotational speed, low shear and gentle product handling. This makes it a very attractive solution for medium, high or very high viscosity fluids, as well as for products sensitive to mechanical stress or with small solid particles in suspension. Compared to other technologies, it provides a combination of smooth pumping, good priming capability and high operational stability.
One of 3P PRINZ’s major strengths is that it does not present this technology as a closed solution, but as a configurable family of pumps adapted to the process. The brand offers different construction executions, customisation and a selection of materials including stainless steel, duplex, super duplex and special alloys, as well as coatings to improve wear or corrosion resistance. This flexibility allows the pump to be adapted to the fluid, temperature, pressure and skid or system integration requirements.
From an operational standpoint, 3P PRINZ hollow disc pumps are distinguished by being self-priming, reversible, capable of handling very high viscosities and maintaining stable operation during transfer, loading, unloading or recirculation. This combination is interesting in processes where minimising pulsations, protecting product quality and ensuring service continuity are sought. Furthermore, their robust design and low speed contribute to longer service life and reduced maintenance requirements. They therefore find a natural fit in oil & gas, marine, chemical, industrial treatment and specialty fluids, where transfer precision, operational flexibility and reliability make the difference.
