System Description

Regenerative blowers
Dustcontrol's turbopumps are regenerative blowers. TPR
has two impellers that are connected for parallel fl ow. Th e
impellers rotate in the blower housing through extremely
low tolerances. Th e pump cannot tolerate contaminated
airfl ow. TPR compresses air and it is therefore natural
that it becomes hot while running.
Cooling air
Turbopumps with TPR designation are parallel con-
nected two stage belt driven units. Cooling air is bled
into the pump through a vacuum relief valve which is
adjustable. Th e vacuum pressure in the system is thereby
maintained at a constant level even if the airfl ow changes.
Th e motor and vacuum relief valve receive cooling air
from the bottom of the unit housing. Th e 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
Th e pump is delivered standard with a back fl ow relief
valve. In multiple pump installations air will not fl ow
back through a non-operating pump.
Belt drive
Th e pump is belt driven. Drive ratio and motor size deter-
mine the capacity of the pump.
If changes are to be made to performance characteristic
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 num-
bers on the last page of this document.
Th ermal overload protection
For protection on the pump bearings the pump has
thermal protection which will shut down the pump at
120
the control panel.
