|Performance curves for mag-drive pumps|
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.

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

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:
