Notice!
The elastomer stator in the
progressing cavity pump is
particularly sensitive to the
elements (ozone, light,
temperature). Depending on the
pump size and type of storage, it
may be necessary to remove the
stator, package it in dark film and
store it within the temperature
range of -10 to +25 °C.
Discuss with factory.
5.3.3 Removing preservative
Notice!
Necessary only for preserved
pumps.
Warning!
Danger of food or water poisoning
by preservatives and cleaning
agents.
►
Use only cleaning agents that
are compatible with the
pumped liquid (
Cleaning
agents, page 12).
►
Completely remove the
preservatives.
Caution!
High water pressure or spray water
may damage the bearing!
►
Do not clean the bearing
areas with spray water or
steam jets.
Caution!
Improper cleaning agents can
damage the universal joint collar,
stator, and seal!
►
Make sure that the cleaning
agent does not attack the
universal joint collar, stator,
and seals.
•
Internal preservatives can be removed by
rinsing the pump with the pumped liquid.
But, if contamination in the pumped liquid
is impermissible, the pump must be
disassembled and the metal parts cleaned
with an approved cleaning agent.
•
Choose cleaning agents appropriate for
the area of usage (
Cleaning agents,
page 12).
•
Dispose of preservatives according to local
regulations.
•
If storage time is greater than 12 months:
-
Inspect all elastomers (stator,
round seal rings, shaft seals) for
shape elasticity and replace if
necessary.
-
Replace elastomers made of EP
rubber (EPDM).
5.3.4 Preservatives
Notice!
Preservatives from Valvoline or
comparable are recommended.

from Table 2, page 2.
Caution!
Use of improper preservatives may
damage the seal, universal joint
collar, and stator elastomer.
►

universal joint collars, stator
elastomers, and rotor screw
are preserved with silicone oil
only.
