Diaphragm pumps - PCM Lagoa

The Lagoa series of reciprocating pumps is designed for metering a wide variety of products, including minerals, paper and oil, across a range of industries.

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:

  • The backward movement of the membrane opens the bottom check valve to allow entry of the fluid, which fills the pumphead

  • The membrane's forward movement closes the bottom check valve, opens the top check valve, and expels the dose of liquid

Options

  • Foot valves
  • Injection rod
  • Safety and retention valves
  • Pulsation dampers
  • Ready to meter assemblies
  • Multiplexing
  • PCM Lagoa™ diaphragm dosing pump
