Spare Parts Kits
Every shutdown for service of a plant
is costly. The time for repair should
therefore be limited to a minimum which
can be accomplished by keeping a
spare pump. The changed pump can
later be repaired at a suitable place and
can then be used as a spare pump. For
maintenance the following spare parts
kits are recommended:
Mechanical seal valid for both ACF5
and UCF5 xTxx seal versions.

Introduction
A screw pump from IMO is a quality product that is designed for a long problem free operation in tough environ-
ments. As all other mechanical products they do however require a certain grade of maintenance and service in
order to guarantee a faultless and economic favourable operation.
For ACF: Note that former version of mechanical seal, called xVxx has been replaced by xTxx. The seals are 100%
interchangeable and since Januari 2016, version xVxx is obsolete.
For UCF: UCF4 mechanical seals xVxx differ from UCF5 seal version xTxx, i.e. not interchangeable.
