Leak-free pumps
March 1st 2008 Plastic, magnet-driven centrifugal
pumps for use in the most
corrosive and challenging
environments have been introduced
by Michael Smith Engineers.
The Finnish Thompson DB Series
of leak-free pumps comprises eight
new models which are available in
polypropylene or PVDF and provide
flows to 27m3/h and heads to 27m.
With non-metallic materials used
for both the housing and all key
wetted components, the pumps
can be used for corrosive liquids in
chemical manufacturing, metal
plating, surface treatment,
wastewater treatment, electronics
manufacture or wherever
hazardous liquids need to be
transferred safely and efficiently.
They are offered in a closecoupled
design for optimum
magnet alignment and provide
extended dry-running capability
when specified with a carbon
bushing and are therefore
protected from system upsets.
High operating efficiency is
claimed, resulting in lower energy
consumption. More articles from Michael Smith Engineers Ltd: |
