Lagoa reciprocating pump principle

The Lagoa reciprocating pump is composed of a membrane which is connected to a piston. Its alternating movement successively fills and empties the pumphead. As illustrated in the diagram below:

  1. The backward movement of the membrane opens the bottom check valve to allow entry of the fluid, which fills the pumphead
  2. The membrane's forward movement closes the bottom check valve, opens the top check valve, and expels the dose of liquid

  4. Pulsation dampers
  5. Ready to meter assemblies
