Savino Barbera also makes other special pumps outside this range of products: in fact, not all of the possible combinations of impellers and motors are included in this chart. Specifically, it is possible to install impellers of various geometries and motors with non-standard power, frequency and protection features. We invite you to contact our technical office for specific needs.

Performance curves

The range of AS vertical centrifugal pumps guarantees flow-rates from 1 to 80 m³/h and heads up to 43 m w.c.
(meters water column). The curves refer to tests with clean cold water (ISO9906). The performance can vary based
on the different characteristics of the pumped liquid. Pumps with different performance are available upon request.

Corrosion resistant plastic materials

In our pumps, all wetted parts are strictly made of corrosion resistant plastic material. Selecting the most suitable chemically-inert polymers is indeed one of the main skills of Savino Barbera. Our choices have always been adaptale to the specific use that our industrial products are intended for.

  • Main thermoplastic materials: PP, PVC, PVDF.
  • One-piece plastic impellers without any metal insert.
  • Shafts with heavy-wall plastic coating.
  • Guide bushings made of charged PTFE, Ceramic or SiC.

The main materials include some highly corrosion resistant polymers: PP, PVC, PVDF.
