Unique technology, guaranteed sturdiness, high quality materials, advanced production processes and rigorous testing combine to make Ragazzini piston pumps a legend in the wine-making industry.
The Ragazzini AISI 316 piston pump satisfies the most diverse needs and can pump:
The Ragazzini piston pump has always been a byword for quality. Since it was invented in the early 1930s, it has proved able to solve pumping problems impossible to resolve with other pumps of the same type.
Its unusually essential, elongated and angular shape (criticised by aesthetes and widely admired among technical experts) is the result of the technology inside: long narrow cylinders, robust sector movements and overdimensioned dampers.
A double acting piston, longer than the diameter of the cylinder, produces a high compression ratio and higher flow rates from lower rpm. This is not only mechanically advantageous, but also delivers a more regular and compact flow and greater pumping capacity thanks to less dead space. The result is high performance with all types of fluid, liquid or dense, hot or cold, even with a high gas content.
A sector movement system guided by a double support ensures perfect piston alignment and delivers the regular thrust necessary for correct operation of the piston gaskets and PTFE gland rings. This reduces energy dispersion and mechanical wear, with evident financial savings.
The shape, size and position (directly on the intake and outlet tubing) of the dampers or pulsation attenuators distribute working pressures uniformly, avoiding turbulence in the pumped fluid. With such high damping near the tubing where the pressure is discharged, the effects of alternating pressures are totally eliminated.
The four-way reversal ball cock with interchangeable PTFE seals guarantees:
