Grundfos MTS screw pump cuts daily energy consumption by over half for KIA Motors
One Kia Motors facility in Korea
was able to reduce its pumping system's energy consumption by
An inefficient and inappropriate pumping system was slowing down
production and forcing up repair costs at KIA Motors in Hwaseong,
Korea. The problem was not only poor performance from their
existing pumps but also the use of a fixed-speed motor supplying a
constant flow of emulsion regardless of the task at hand and its
A Grundfos MTS screw pump along with a CUE frequency converter
was recommended as a more reliable solution that would save money
in the long run. The MTS screw pump has an integrated frequency
converter which affects flow rate and rotation speed. It can reduce
bypass flow and potentially eliminate flushing flow and has an
adjustable pumping speed. Following consultation with KIA
Motors, Grundfos implemented a field test to try out their
The results were astounding,
"With the integrated frequency converter, the MTS cut the flow
rate and rotation speed in half"
Says, Wonjae Kim, Industry Sales Engineer, Grundfos Korea
This cut in flow rate meant that the Grundfos MTS could maintain
a higher pressure than the previous pump while only operating at
49% pump speed (about 30Hz). Operational noise was reduced and
strikingly, power consumption was reduced by 60%. The previous pump
used 110 kWh/day, whereas the Grundfos MTS used 45 kWh/day.
Operator of Kia Motors, Il Pyo Hong was delighted with the
"We have witnessed a remarkable performance. This system will
help us to save on the operation cost."
All in all, a winning solution for KIA motors.
