Lagoa principle

The PCM Lagoa pump is composed of a membrane connected to a piston which alternating movement successively fills ans empties the pumphead.

  • The backward movement of the membrane opens the bottom check valve and allows the entry of fluid, which fills the pumphead.
  • The forward movement of the movement closes the bottom check valve, opens the top check valve and expels the dose.


  • Foot valves
  • Injection rod
  • Safety and retention valves
  • Pulsation dampers
  • "Ready-to-meter" assemblies
  • Multiplexing
