This pump measures and mixes 2 components A and B to a single defined volume proportion (see data
sheet of the product).
The fluid sections HA and HB are coupled to an air motor MP. Their sizes have been calculated in order
that each delivers the components A and B to the predetermined proportion.
Fluid section HA draws and delivers the BASE A.
Fluid section HB draws and delivers the CATALYST B.
When pulling gun trigger (19), proportioning pump starts cycling and draws the BASE and the CATALYST.
Simultaneously, they are delivered in valves (11 and 12), the check valves (13 and 14) and are mixed in
the static mixer (15). The mixed material then goes towards the gun through hose (17).
As soon as the trigger is released, the proportioning pump stops cycling :
the regulator (9) regulates the air pressure on the pump, thus regulates the material pressure,
the regulator (8) regulates the atomizing air pressure to the gun.
Nota :
The valve (11) is a three ways' valve :
- handle horizontally
⇒
fluid circulation (priming stage),
- handle vertically
⇒
fluid towards mixer (working stage, flushing stage).
The valve (12) is a color changer fitted with 2 fluid valves. These valves are piloted pneumatically
alternately, connecting the air tube on one or the other valve :
Left connection
⇒
fluid circulation (priming
stage)
Right connection
⇒
fluid towards mixer (working
stage).
Nota : During the FLUSHING stage,
- the BASE fluid section draws solvent; that solvent is exhausted towards the manifold, the mixer and the
gun.
the BASE circuit and the mixed circuit will be flushed.
- the catalyst circulates. The CATALYST circuit is not flushed.
