Field of application: flow free mediums with aggressive; abrasive; viscous; radioactive; flammable; odorous; toxic characteristics. Capability characteristics: leakage free; dry run safety; high quality materials; continuous operation with

sera C409.2KM controllable piston diaphragm pumps are leakage-free oscillating displacement pumps designed for the dosing of volumes up to 190 l/h and up to maximum 80 bar. They are an ideal combination of the high supply pressure of a piston pump and the perfect leak-proofness of a diaphragm pump. Field of application - flow-free mediums with

sera R410.2KM piston diaphragm pumps are leak-free oscillating displacement pumps designed for the dosing of volumes up from 30 l/h to 850 l/h. They are an ideal combination of the high supply pressure of a piston pump and the perfect leak-proof diaphragm pump. Field of application - flow free mediums with: aggressive; abrasive; viscous

RS204.1 / CS204.1 are electronically controlled, self ventilating dosing pumps suitable for many applications. They are designed for industrial use and guarantee highest operational reliability. They are used for the dosing of easily degassing media in combination with small liquid quantities. Without an automatic venting valve, a failure of the

The sera controllable diaphragm dosing pumps types C409.2 + C410.2 are electronically controlled dosing pumps that can be used for many applications. A wide range of pump head materials is available. C series pumps can provide solutions for sophisticated and demanding applications. Typical applications include the dosing of liquid chemicals in

sera R409.2-KM piston diaphragm pumps are leak-free oscillating displacement pumps for the dosing of volumes 7.5 l/h to 190 l/h. A further advantage compared with conventional diaphragm pumps is the doubling or, depending on application, even quadrupling of diaphragm lifetimes. This helps to reduce the life cycle cost (operational cost
