Description and operation
This group consists of one single centrifugal pump. This pump receives the additive from a tank and drives it to a measuring glass. Then the pump draws the additive from the measuring glass and drives it to the concrete mixture.
The assembly has an electrically operated valve and one pressure regulator filter in order to control the flow of the additive at the entrance. At the outlet pipe this flow is controlled by a flow meter. Moreover, it’s supplied with three check valves in order to prevent the backflow.
