Magnetically driven, sealless pumps
from M Pumps S.R.L (previously 3M
Pumps) and available from Pump
Engineering, are said to offer leakfree,
low-maintenance and reliable
pumping, especially when the process
involves aggressive, corrosive fluids.

To counter eddy current losses, M
Pumps has produced a hybrid rear
shell design based on an inner shell
made from Hastelloy C and an outer
shell which consists of a carbon
filament wrapped around the steel
outer shell. The result is a composite
rear shell construction with the
properties of a non-metallic material.

Trials have shown its resistance to
temperatures above 300°C, pressure
resistance to 500 bar and a reduction
in eddy current losses by up to 90%.
