Pompe Cucchi (Italy) has introduced new magnetic coupled gear metering pumps. The standard version is made of AISI 316L stainless steel. Special versions in titanium, Hastelloy, Sanycro 28, PVDF, or any other machinable material, may be made on request. Pumps obtained from steel bars and not from casting guarantee homogeneous and uniform material quality, thus avoiding unpleasant inconveniences which may be caused by cracking or shrinkage. The shafts and gears, which are also made of AISI 316L stainless steel, are put through special anti-wear and anti-seizure heat treatment. The series has been designed in order to allow the use of steel bars in the manufacturing of the pump components. The N series pumps are suitable for all those applications in which not only a constant pressure is required, but also considerable precision in dosage. The complete absence of pulsation on the delivery side of the pump optimises the accuracy of the flow meter reading and the prompt response to the capacity changes assures the correct dosage at all times.
