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 OMA horizontal centrifugal pumps guarantees a work capacity with flow-rates from 1 to 90 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. Non-metallic pumps with
different performance features are available upon request.

Corrosion resistant plastic materials

In our corrosion-proof pumps, all parts in direct contact with aggressive liquid are strictly made of corrosion resistant plastic material. Selecting the most suitable plastic material is indeed one of the main skills of Savino Barbera. Our choices have always been adaptable to the specific use that our industrial products are intended for.

  • Main plastic materials: PP, PVC, PVDF.
  • One-piece plastic impellers without any metal insert.
  • Shafts with heavy-wall plastic coating.
  • Sliding elements made of Ceramic or Silicon carbide.

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

Savino Barbera mechanical seal

The mechanical seal of our chemical pumps is a seal for rotating shafts exclusively designed by Savino Barbera.
It was conceived to be fully corrosion resistant and has the following features:

  • Very simple structure: only three elements.
  • Single mechanical seal, internally assembled and balanced.
  • Internal mounting for maximum cooling of its faces.
  • Sliding parts lubricated by the pumped liquid.
  • Self-cleaning due to the centrifugal force.
  • Ready-to-fit seal (no need for registrations).

L1: max. liquid level
L2: min. liquid level

Occasional use and storage: what to do

  • Pump casing, in case of storage, occasional use or inactivity, must be kept completely full of liquid always
    to avoid the risk of seal rings sticking.
  • After a long period of inactivity and before restarting: extract the motor fan cover and verify, by manually
    rotating the motor shaft, that the pump shaft can smoothly turn. if not , the mechanical seal rings may be
    stuck and the seal should be unblocked.
