  • a pump capable of delivering both air under pressure and the coating product under pressure.
  • each sprayer can be supplied by a hose of different length and / or diameter.
  • pressure regulators are mounted on the pump or the pump part which delivers the coating product under pressure. The regulators are used to avoid or limit the pressure fluctuations in a coating product supply pipe to the projector and to adjust the pressures in each pipe independently, in order to obtain iso pressure at each projector.
  • Certain coating products such as those used to apply a stain to wood, are very liquid, that is to say have a particularly low viscosity, close to that of water.
  • the supply pressure of the spraying zone of a projector must be low, in particular less than 0.5 bar.
  • a volume provided inside the body of a sprayer to supply this spraying zone must itself be at low pressure. This involves supplying the projector with a coating product at low pressure, which causes the regulator to operate outside its nominal pressure range, to the point that it is no longer efficient and no longer allows hide pump stroke reversals. This results in pressure fluctuations in the feed pipe to the projector, which leads to uneven application of the coating material.

  • a pressure regulator arranged at the outlet of a feed pump of the sprayer can be implemented in its nominal operating pressure range, so that it remains effective, even when the pressure of the sprayed coating product. is weak.
  • the fact that the restrictor is made of a material that is softer than the material of the connecting member promotes sealing.
