System Description
Regenerative blowers
Dustcontrol’s turbopumps are regenerative blo-
wers. TSR has two impellers that are connected
for series fl ow. The impellers rotate in the blower
housing through extremely low tolerances. The
pump cannot tolerate contaminated airfl ow. TSR
compresses air and it is therefore natural that it
becomes hot while running.
Cooling air
Turbopumps with TSR designation are series con-
nected two stage belt driven units. Cooling air is
introduced into the pump through a slot between
the two stages. In this way the second stage cools
the fi rst stage indirectly.
The motor receive cooling air from the bottom of
the unit housing. The free passage of cooling air
must be ensured. As standard screen skirts are
delivered with the pump as an protecting against
leaves, papers etc.
Back fl ow valve
A back fl ow valve must be optionally installed on
the inlet side of the unit when several units are to
be installed in parallel.
Belt drive
The pump is belt driven. Drive ratio and motor size
determine the capacity of the pump.
If changes are to be made to performance charac-
teristic of the pump, this can be done by changing
the motor and drive ratio. Contact Dustcontrol
and you will recieve more information. Please see
addresses and phone numbers on the last page of
this document.
Thermal overload protection
For protection on the pump bearings the pump has
thermal protection which will shut down the pump
at 120
O
C. The thermal protection has to be con-
nected to the control panel.
