with resin. Many factors should be considered when deciding to use these
materials. One, not often considered, is the additional wear and tear on equipment.
Fillers do increase wear. To what extent, is based on many factors such as amount
and type of filler, volume dispensed and type of system used (spray, pour, etc.).
The following adjustments to the equipment and procedures are recommended for
systems using filled resins.
1. Magnum Venus Products has available the following parts for longer wear:
A. Carbide gun needles.
B. Carbide gun seats.
C. Carbide spray tips.
D. Hardened resin pump cylinders.
2. Reversing the direction of the bottom piston cup in the resin pump will
increase pump stroke efficiency with filled systems only.
3. Remove or increase the mesh size of all resin pump filler screens to prevent
flow restrictions or filler separation.
4. Auxiliary heat applied to the filled resin may be needed to create a spray fan.
Note: consult a Magnum Venus Products representative if in doubt.
5. Never leave filled resin in a system long enough for the filler to separate and
settle on balls/seats in the system.
6. Never use improperly mixed filler in a system. (Consult your resin/filler
representative for proper materials and mixing procedures.) It is important to
keep filled resin systems under constant agitation.
7. Never flush a filled system with solvent. This will usually remove the resin
and leave the filler. Always pump non-filled resin through the system to
remove filled resin, and then flush with solvent.
This information and procedures are only an aid to assist you in using your Magnum
Venus Products equipment properly. Not all Magnum Venus systems can be used with
fillers, nor can all fillers be used with Magnum Venus systems. Always consult your
Magnum Venus Products representative when considering a filled system.
