CHAPTER 4
BALANCING RESIN AND CATALYST
1. Place a suitable container, one that will hold 2 gallons or more, under gun head.
2. With turbulent mixer and nozzle in place, open ball valve to power head of resin pump slowly.
When ball valve is open, slowly turn regulator to the power head to desired PSI (50-60 PSI for
most applications).
The pump will stall out when fluid pressure is equal to the air pressure applied to power head.
NOTE: There is a 10:1 ratio between air pressure applied to pump and the fluid pressure that
results due to the mechanical advantage in piston sizes.
3. With a container under gun and safety glasses on, trigger gun and allow the system to operate
for approximately 10-15 strokes. As system operates note the flow of material. It should be
steady and even, no pulsation when resin pump changes direction. If colored catalyst is used, a
fairly uniform mix should be coming from gun, provided turbulent mixer is in place.
4. After 10-15 strokes of the resin pump, release the trigger button, and pump will stall out when
fluid and air pressure equalize.
5. Flush gun to clean gun mix chamber.
6. Observe the poly ball and fluid level in catalyst accumulator. They should be no higher than 2-
1/2 to 3 inches from the top or bottom of accumulator. A perfect charge will place the poly ball
and fluid level in the center of accumulator.
When accumulators are properly charged and material is balanced and available at gun head,
the pour tube system can be installed.
RESIN DISTRIBUTION SYSTEM (POUR TUBES)
NOTE: All connections for the pour tube system are “O” ring sealed. A liberal application of
lubricant, preferably MVP Grease, is recommended before installation. All connections and
seals in the resin distribution system are designed for hand assembly and disassembly. Care
should be exercised to insure all joints, threads, and seals are well lubricated. To install resin
distribution system, assemble as outlined below.
1. If the turbulent mixer and nozzle have not been previously installed, lubricate the nozzle threads
and “O” ring with MVP Grease and install.
NOTE: Threads may gall and damage nozzle cap if not lubricated.
2. Lubricate “O” rings in the manifold block and check to see if the static mixer is in place and all
plugs are pressure tight.
3. Install pour tube manifold onto the gun nozzle. The pour tube manifold must be perpendicular
to the gun and roll plate.
4. Rotate manifold block into position parallel to roll plate, and pull down until the block rests on the
angle bracket.
