The standardized dimensional
There are several advantages of
opting for an OH5 design in such
scenarios: reduced footprint and
weight; longer meantime between
failures; and ultimately, diminished
cost and carbon footprint. Moreover,
the OH5 design's vertical, in-line
configuration offers additional
benefits, such as simplified
maintenance access and enhanced
fluid flow efficiency, making it a
compelling choice for a diverse
range of operational requirements.
This has significant benefits
especially for offshore and prepackaged
skid applications where
space is at a premium, and where
they could be used to pump
anything from boiler feed to oily
surface water, crude oil, and sour
water to hydrocyclone feed and
condensate recovery.
LIGHTER WEIGHT, SMALLER
FOOTPRINT DESIGN
The highly versatile OH5 pumps
typically weigh around 25 percent
less than a comparable horizontally
mounted pump because of their lack
of a large baseplate. This also means
that pump installation work can be
started at an early stage. The overall
lead time can be reduced by pouring
the sole plate and welding pipework
in situ before the actual pump is
on-site. This presents opportunities
to absorb any project overruns by
completing installation activities in
parallel rather than in sequence.

features of OH5 designs,
compliant with BS4082, facilitate
the straightforward design and
provision of installation templates,
which can be supplied prior
to pump delivery. This enables
the installation process to
proceed concurrently rather than
sequentially, with tasks such as
grouting of the baseplate and
welding of pipework completed
ahead of the pump's arrival. Such an
approach offers several advantages
to the customer: it allows absorption
of any project overruns, streamlines
the installation timeline, and provides
a reusable method for preventing
contaminants from entering the
process system. Additionally, the
installation dummy serves the dual
purpose of keeping the line open
for the process if needed, further
enhancing operational flexibility
and efficiency.
CONTRIBUTION
TOWARDS SUSTAINABLE
DEVELOPMENT GOALS
Of increasing importance to
manufacturers is their adherence
to the United Nation's Sustainable
Development Goals. This is another
area where the OH5 pump has
a big impact. As it involves less
steel in its configuration, there is
already a reduction in carbon in its
manufacture. Because of its compact
nature, its installation requires less
supporting concrete and steel and
lightens the overall weight, important
for LNG ships and off-shore rigs.
What's more, it costs less to ship and
accounts for fewer emissions than
larger, heavier OH2 equivalents.
OH2 OR OH5-THAT IS
THE QUESTION
Of course, not every API 610
pumping application can be switched
to an OH5. There are many scenarios
where OH2 or other OH solutions
will be optimal-for example,
where higher energy applications,
or applications with higher
temperatures. However, just because
an application has traditionally
used the OH2, it doesn't mean that
it always has to. From a safety, cost,
size, weight, and environmental
perspective, the OH5 alternative
offers some compelling benefits.
