RECOMMENDED SPARES
KOPkits. The basic Isochem KOPkit consists of
the following parts which are recommended as
spares:
Drive Shaft
Idler Shaft
Drive Gear
Idler Gear
Drive Keys
Bearings
Wear Plates
Bearing Lock Pins
Magnet Retaining Rings
Drive Gear Retaining Rings
Idler Gear Retaining Rings
Housing O-Rings
Can O-Ring
A KOPkit is completely identified by placing the
letter "K" before the pump significant model
number and deleting the hyphens. Example:
A KOPkit for a GMC6-ACC-KKO pump would
be designated as KGMC6ACCKKO.
4. General maintenance precautions to observe
are:

Drain and flush pump and magnetic drive
before any pump disassembly. Access to
the magnetic drive area is provided by a
drain connection in the pump main cover.

The exposed magnets on the drive
magnet assembly are very fragile and will
chip easily. Use extreme care in handling
them.

Don't wear a wrist watch in the vicinity of
the drive or driven magnets as it may be
damaged.

Take care to avoid particles or objects
from attaching themselves to the drive
magnets. It is difficult to remove small
particles and larger objects could be
attracted with enough force to break the
magnets.

Be careful during disassembly and
reassembly of the drive and driven
magnet assemblies. Assembly and
disassembly can best be described as a
feat of strength. The attraction forces
are high and when the magnets come close
together there is a strong tendency to snap
together suddenly, possibly causing
pinching or worse to fingers. The attraction
forces are strongest on the GMC12 and
GMC16 pumps. Your representative is fully
equipped and prepared to provide
maintenance support. See Figure 2.
5. Caution. Do not machine the magnets in the
drive or driven magnet assemblies. The dust
that would be produced is highly inflammable.
6. The significant model number stamped on the
pump nameplate, identifies the pump type and
other details. Refer to the significant model
number chart if you are unsure of exactly what
type of pump you have.
Always refer to the full model and serial
number in any correspondence with your
Isochem representative. Drawings and a
consolidated bill of materials for each Isochem
pump are included in this manual.
Recommended spare parts are denoted on the
consolidated bill of materials.
