Re-engineering
ClydeUnion Pumps Aftermarket Technical Services
team has experience across a range of services
on critical rotating and reciprocating equipment to
improve operational safety, reliability and efficiency.
The re-engineering of the 2D 150-68 screw pump for
the oil and gas market is one of our success stories
documented in our library of case studies. These case
studies highlight the requirement from the customer,
how we achieved the goal and the process we followed
to deliver the improvements.

Situation
The end user placed a partial order for its bitumen process 2D
150-68 screw pump. The purpose of this order was to perform
a pump overhaul, especially focused on the replacement of
bearing housings and heating boxes. It emerged that these parts
had been damaged over the years and re-machined several
times by the end user to allow correct alignment of the shafts.
Challenge
Guinard Pumps were the original pump set packager of this
equipment in 1981, however, were not the designer of the screw
pump itself. For this part order, ClydeUnion Pumps contacted the
original designer to supply bearing housings and heating boxes.
In the first instance, a proposal was submitted to and approved
by ClydeUnion Pumps. However the original supplier of the 2D
150-68 screw pump discovered later that they were unable
to manufacture the cast parts, because the patterns had been
destroyed.
