Membrane motor-driven dosing pumps.The metering pumps ST-D series are driven by an electric motor, the dosage takes place thanks to a PTFE
membrane. The ST-D series pumps make their robustness and reliability their main characteristic.
Plunger Piston Motor-driven pumps.The metering pumps P series are driven by an electric motor, the dosage takes place thanks to a piston. The
P series pumps make their robustness and reliability their main characteristic
