Mixerpac 2564 - Installation and Maintenance Instruction for Machinery Parts
FLOWSERVE and will lead, without special tools, to damage.
!
Vibrations must not be allowed to reach the installed MIXERPAC when the
machine is operating or in particular when it is shut down. Vibrations can be
stopped e.g. by structural measures on the machine.
5.2
!
The installation chamber for the MIXERPAC must be checked against the cor-
responding drawing and table of dimensions so that the bearing is subjected
only to the loads generated by operations in accordance with these instructions.
It must be ensured that all dimensions, surface qualities and tolerances (e.g.
concentricity, runout, fits) are observed. The specifications under e.g. ISO 21049
or API 682, DIN 28161, FLOWSERVE publications FSD101 respectively FSD127
must be observed.
5.3 Ensure the highest degree of cleanness. Force must not be used to install the seal.
Use only suitable tools and devices.
5.4 The seal faces of the MIXERPAC are important functional sections and may not be
damaged.
5.5 All functional and assembly areas for the secondary seals (e.g. O-rings) must be
dimensionally accurate, free of scratches and burrs, flash-free and rounded.
5.6 The fitting surfaces of the MIXERPAC and the installation chamber must be
undamaged and the feed pipes and ring channels dry. Ensure the highest degree of
cleanness.
5.7 A thin coat of product-compatible grease (e. g. Molykote M55) is to be applied to the
sealing elements. Excess grease is to be avoided.
5.8 Depending on the installation direction, a lubricant, (e. g. Molykote D321R) or PTFE
spray without solvent, must be applied to the shaft or shaft sleeve.
!
The areas for the clamp-connections must remain free of grease, otherwise the
adhesive force will become inadequate for correct functioning.
6.0 INSTALLATION
6.1 The MIXERPAC is installed in the mixer in accordance with the instructions from the
machine manufacturer and with consideration to the following recommendations.
The machine to take the MIXERPAC must be earthed in accordance with the
applicable regulations for electrical installations (e. g. VDE rules) to conduct
away any electrostatic build-up and so prevent spark formation.
Parts of the MIXERPAC, which need to be entered during assembly works, need
to be secured against slipping, stumbling or falling (e. g. by holding devices).
