Application Notes
Pumps in the oil and gas industry
Whether it’s for an upstream drilling site, an LNG export terminal,
or a crude oil pipeline, pumps are widely used throughout the oil
and gas industry. By converting mechanical energy, pumps are
used to accelerate and transport fluids from one location or
process to another, with pump size being proportional to the
volume being moved. Traditionally, these pumps have been
driven by fixed speed electric motors. However pumps driven by a
variable speed electric motor drive system have proven to be a
better option in most cases.
In today’s fast paced and complex world, pump users face
many challenges with their pump’s drivers.
Maximizing equipment operation lifetime
Operating a pump with a fixed speed motor can put significant mechanical and electrical stress on the entire drive train.
Over time, these stresses will lead to failure of the equipment, requiring significant repair or replacement. In order to
maximize the return on their investment, pump owners and
operators need to keep their pump equipment running for as
long as possible.
Keeping operating and maintenance costs low
The construction of oil and gas infrastructure is a significant
investment in the eyes of an oil and gas company. If equipment is not running at the best efficiency, this cuts into
profits and delays the payback period of the project.
Furthermore, equipment that is not functioning due to
frequent outages (planned or unplanned) results in even
more financial losses.
Drive failure
Even when an electric variable speed drive system is used as
a pump driver, a catastrophic drive failure can bring down the
pump application, and possibly even the entire facility. Keeping an electrically driven pump online is critical to achieving
maximum profitability.

Making things right with Siemens Integrated Drive Systems
Reduce equipment stress and extend pump lifetime
A pump driven by a variable speed drive system minimizes the
electrical and mechanical stresses, decreasing the likelihood of
failure, and increasing its life of operation.
Minimize OPEX and service costs
Due to reduction of stress on the drive train, planned and
unplanned outages are minimized with an electric variable speed
drive systems. Electric variable speed drive systems are more

efficient in their operation as well, since they provide the user
with broader and more accurate speed control. This minimizes
OPEX and improves profitability.
Reduce electric drive shutdowns
Electric drive failures can happen, but don’t need to bring down
the entire pump and facility. With the patented cell bypass
technology included in Siemens Perfect Harmony products, these
drives can continue functioning even if a few cells were to fail.
Integrated Drive Systems with Siemens Perfect Harmony drives
help maximize existing equipment’s uptime.
