Performance curves

The range of BM magnetic drive pumps guarantees flow-rates from 1 to 30 m³/h and heads up to 26 m w.c. (meters water column). The performance can change as the characteristics of the liquid being pumped varies. Pumps with 60 Hz motors are available upon request.

Stainless steel, Hastelloy and Titanium.

In BM sealless metallic pumps, the pump and the impeller are made of AISI 316 stainless steel (standard version). Other metals are available upon request: Hastelloy and Titanium.

Material of pumping units:

  • Pumps and impellers made of stainless steel AISI 316 (standard version).
  • Bushings: graphite or filled PTFE.
  • Shaft: C276 Hastelloy.
  • O-ring: EPDM or FPM (Viton).

Magnetic coupling materials:

  • Permanent magnets made from neodynium-iron-boron (NeFeBo).

Mag-drive pump options

Savino Barbera magnetically coupled pumps can be assembled with some optional equipment:

  • 4 pole motors with 60 Hz power (1450 rpm).
  • Explosion proof motors (Ex-d).
  • Zone 1 and 2 ATEX pumps.
  • Base-plate made of PP in three different sizes.
  • Connections: backing rings, hose adaptors, male threads (depending upon the models).

Mechanical seal or magnetic coupling?

The choice between pumps with mechanical seal and sealless mag-drive pumps may be misled by incorrect
installation habits. For example, we are sometimes asked to provide magnetically coupled pumps not compatible
with applications requiring a leake-free pumpage: those who prefer the magnetic coupling can in fact presume
that the transmission through magnetic joint is a safer system compared to the mechanical seal. Howerver, if
on one hand the mechanical seal is more easily subject to leakage, on the other hand the supposed leak-free
design of permanent magnets must be taken into consideration because it can become a problem for the nature
of some liquids. To make a calculated technical choice, we invite you to read this section:
