Pumps and Systems<br />
Progressing cavity pumps<br />

to suit a variety of operating parameters.<br />
tional progressive cavity pump.<br />
Maintenance work is required<br />
less frequently and is easier to<br />
plan. This relieves the burden on<br />
maintenance personnel and creates<br />
free capacity – which is also<br />
financially beneficial, especially<br />
in times of a shortage of skilled<br />
workers. This is particularly advantageous<br />
for companies with<br />
pumps in remote use. If the<br />
HiCone is equipped with automatic<br />
readjustment, the company<br />
has the option of observing<br />
and recording the wear of the<br />
pump on its monitors and optionally<br />
also on the pump. This<br />
means that maintenance work<br />
can be planned very precisely.<br />
Responding to process changes<br />
The fact that the HiCone can be<br />
individually adapted to the applicable<br />
operating parameters at<br />
any given time, such as temperature<br />
or viscosity, also contributes<br />
to this. The adjustment system<br />
ensures that the rotor and stator<br />
are optimally positioned in relation<br />
to each other. For example,<br />
the user can adjust them to different<br />
viscosities in the best possible<br />
way. The higher the viscosity,<br />
the better they seal the gap<br />
in the pump. The clamping can<br />
therefore be reduced. This is<br />
done by the user pulling the rotor<br />
out slightly.<br />
This also applies to applications<br />
with high temperatures or<br />
temperature changes: if the rubber<br />
in the stator expands due to<br />
high temperatures, there is increased<br />
clamping between the<br />
rotor and stator. To reduce this,<br />
the rotor is retracted. If the temperature<br />
then drops again, the<br />
rubber in the stator contracts. As<br />
a result, the clamping force is reduced<br />
and the pumping capacity<br />
decreases. In this case, the rotor<br />
is pushed in further until the desired<br />
clamping is achieved again.<br />
High flexibility: mobile sludge<br />
dewatering<br />
Companies working in the area<br />
of mobile sludge dewatering also<br />
benefit from this high flexibility<br />
of the HiCone. Here, the pump<br />
technology must be designed<br />
for high temperature fluctuations.<br />
The sludge is sucked out of<br />
the respective system by a progressive<br />
cavity pump and dewatered<br />
in a container. The operator<br />
uses this device at a number<br />
of different industrial companies.<br />
The sludge there varies between<br />
temperatures of 20 to 60<br />
degrees Celsius. To cover all applications,<br />
the operator therefore<br />
uses two progressive cavity<br />
pumps: a “normal” one for temperatures<br />
of up to 40 degrees<br />
and a progressive cavity pump<br />
with an undersized stator.<br />
By using the HiCone, the<br />
operator now saves the cost of a<br />
conventional progressive cavity<br />
pump and the associated power<br />
electronics. The company benefits<br />
from lower acquisition costs<br />
and more space in the container<br />
and can therefore react even more<br />
flexibly to the conditions on site.<br />
Energy-efficient pumping<br />
The HiCone is also particularly<br />
energy-efficient. This is due to its<br />
intelligent automatic startup. The<br />
size of the drive motor in a progressive<br />
cavity pump is usually<br />
determined by the high starting<br />
torque. Thanks to the adjustable<br />
clamping between rotor and stator,<br />
the motor needs less power<br />
than in a conventional progressive<br />
cavity pump. The torque<br />
when starting up the pump is<br />
minimized and the power requirement<br />
is reduced. The startup<br />
process is fully automatic.<br />
Due to the smaller drive motor,<br />
the frequency converter on the<br />
pump is also smaller.<br />
