Description

Pompe Cucchi’s S/SK/SM Series Gear Pumps are robust transfer solutions designed for handling fluids with viscosities from 1 to 100,000 cPs, delivering smooth, pulsation‑free flow with exceptional reliability. Machined from solid steel bars to eliminate casting defects, these pumps are available in cast iron, carbon steel, bronze, or stainless steel, with special versions in Hastelloy C, Titanium, or Duplex for demanding environments. The SK variant features graphite bushings and shims for dry‑run protection, while the SM series offers stainless steel construction for superior corrosion resistance. With flow rates up to 60,000 L/h, pressures up to 20 bar, and operating temperatures reaching 250 °C, the S/SK/SM Series is ideal for chemical, food, agricultural, and industrial applications requiring durability, precision, and compliance with ISO, ATEX, and API standards.
