WORKING PRINCIPLE
The unit 3000 is defined “Diaphragm pump”.
Piston pump is used for high pressure painting without air.
This unit is powered by an gasoline engine. An eccentric mounted
on the motor shaft drivers a piston which conveys oil to a diaphragm
on every stroke.
The moving diaphragm draws the paint in through the intake
valve, compresses it and drives it out through the tiny hole in the
spray gun nozzle.
The Lariette is the smallets machine available in the range- it
is good value for money for small-medium operations with light
viscosity water and solvent based paints- based on the LARIETTE
AIRLESS DIAPHRAGM PUMP it can run one gun only - the gun
TECHNICAL DATA
is removable for side spraying operations (10 mt. hose) - Glass
beads dispenser available on request.
Being an airless machine, the paint is atomised without air,
therefore without overspray, blasting away sand and dirt.
It will provide sharp high quality lines, with even paint thickness.
Thanks to the possibility of a quick colour change, no pressure tanks
to be cleaned, it allow a 30% increase of the production rate.
