Magnetic centrifugal pumps overview
Magnetically coupled centrifugal pumps by RENNER are mainly used for industrial applications. Motors and pumps are mechanically separated. Therefore the conventional sealing of the drive shaft is no longer necessary, which helps to avoid leakage and corrosion problems.
The RENNER Module System allows the specific combination of different types of pumps, according to your application. Our pumps are made of extremely resistant materials. The functional design facilitates installation and maintenance of the pumps and guarantees their long life.
Aggressive, inflammable, smelling, explosive, precious or highly pure fluids used in chemical, biochemical or electroplating industries, in laboratories or medical appliances – no matter what fluid you want to deliver, RENNER has the right pump to do the job.
Choice of material
Metal-free and all-plastic making of our pumps is standard since this design guarantees best protection from corrosion. Housings may be also made of special stainless steel. We offer the right combination of materials for any fluid to be delivered, depending on its temperature.
