To meet the requirements of ATEX process is a batch operation, the
regulations a temperature probe can pump, along with all of the other
production equipment, needs to be
cleaned between cycles. Often this
would be a completely manual process
with the corresponding effort
and expenditure.
The challenge was presented to
the NETZSCH development engineers
if it would be possible to construct
the pump in order that it could be
cleaned using an automated system.
This would require additional
constructional changes to the pump.
These included adding a flushing connection
into the magnetic coupling.
However, major adjustments were
needed in the area of the pump suction
housing and coupling rod.
A progressing cavity pump requires
a coupling rod that accommodates
the requirements of both the
rotational and eccentric movements.
For battery applications involving anode
and cathode slurries, the most
suitable solution would be to select
a flexible shaft. Such an arrangement
has the benefit of needing no joints
to accommodate the eccentric move-
