Multi-layer diaphragm pumps C409.2-ML, controllable
The use of multi-layer diaphragms makes it possible to realise dosing tasks that are demanding in terms of safety. Increased safety requirements are guaranteed by safe diaphragm monitoring (pressure switch, pressure gauge, etc.).

Structure and function
Each drive unit consists of a tried-and-tested motor, coupled with a reciprocating gear mechanism within a robust housing. sera housings are designed to withstand even the harshest operating conditions. The material thickness and surface treatment ensure resistance even to chemical attack. The flow rate is constant or infinitely variable. In the adjustable version, this is done manually by changing the stroke length. Automatic flow rate adjustment can be achieved via the following options:
The dosing pumps can be equipped with a choice of two different electronic control systems (Pro or Pro+).
