Component Identification
Catalyst Pump
The catalyst pump supplies catalyst to the spray gun.
Pump arm (U): controls catalyst flow.
Ratio adjustment knob (V1): use to lock/unlock pump position and adjust the resin to catalyst ratio. It is easiest to adjust the ratio when the pump is at the bottom of the stroke.
Pivot point (V2): when pump is moved to adjust ratio, this point stays stationary.
High pressure relief valve (W): directs catalyst to gun or back to tank to relieve pressure. It also automatically relieves pressure if it exceeds normal working pressure.
Fluid pressure gauge (X): indicates catalyst fluid pres- sure.
Fluid inlet (Y): fluid inlet from the catalyst reservoir.
Fluid Inlet Ball Valve (Y2): controls flow of catalyst to the catalyst pump.

Weep line (Z): In the event of a throat seal failure, the fluid will flow into the weep line and back to the catalyst reservoir.
Fluid outlet (Z1): fluid out to the gun.
Fluid recirculation/high pressure relief (Z2): fluid out- let to the catalyst reservoir.
Low pressure relief valve (Z3): External mix systems only. Directs catalyst to gun or back to tank to relieve pressure.
