Piston diaphragm pumps type C409.2 KM, controllable
sera piston diaphragm pumps type C409.2-KM are leakage-free oscillating positive displacement pumps. They ideally combine the high delivery pressure of a piston pump with the perfect tightness of a diaphragm pump.
- Max. operating pressure
- 80 bar
- Flow rate
- 10 l/h until 190 l/h

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+).
