Company insight Heavy-duty T


his year, the PERIPRO peristaltic pump has been added to the portfolio of the world’s leading


supplier in the field of positive displacement pumps – alongside the well- known technologies of NEMO progressing cavity pumps, TORNADO rotary lobe pumps and NOTOS multi-screw pumps. The PERIPRO peristaltic pump has a heavy-duty design and is therefore particularly suitable for highly aggressive and abrasive media such as lime milk, active charcoal, sodium hypochlorite or hydrochloric acid.


The new development has a robust monoblock design with a bearing box and hose compression system. Components that are prone to wear, such as valves and mechanical seals, are not required with this pump technology. The pump has a high intake capacity and unlimited dry-running capacity, which makes it a uniquely functional and efficient pump, even with pressures up to 10 bar. Compared with peristaltic pumps with slide shoe technology, it also saves 90% lubricants and 30% energy. It is available in three variants for industrial, chemical and food applications.


“One reason for the robustness of the pump in demanding applications up to 10 bar is its heavy-duty design with extremely durable and resistant hose materials,” explains Roger Willis, head of global business field chemicals and paper at NETZSCH. As no wear parts such as valves or mechanical seals are used, and the PERIPRO additionally has a monoblock design with a bearing box, it is suitable for a variety of demanding tasks such as pumping corrosive products. The bearing is installed in the pump housing, ensuring optimum alignment and complete absorption of the loads from the drive shaft.

peristaltic pump


For the most difficult cases, NETZSCH has developed a heavy-duty peristaltic pump to deal with particularly aggressive and abrasive media.


very high quality. Thanks to controlled tolerances, it ensures optimum compression as well as fast installation. Overall, the PERIPRO peristaltic pump not only saves a significant amount of energy compared with units with slide shoe technology but also ensures more operating hours per pump, longer service life of the hose and easier operation.


Special versions for chemicals and food industries


The PERIPRO peristaltic pump has a heavy-duty design suitable for abrasive media.


Optimum hose compression In addition, there is a hose compression system with XXL rollers for lower energy costs and more efficiency. The large diameter of the rollers can cover a broader area of the hose for optimum compression, while the absence of friction results in significantly lower wear on the hose overall. This results in more efficiency, lower energy consumption and longer service life.


The PERIPRO hose pumps are available in three different versions – as a standard version for industrial applications as well as for chemicals and food applications. The version for chemical applications is completely protected by a TEFZEL coating that is resistant to highly corrosive acids and all types of difficult chemicals. Therefore it can be used for dosing sodium hypochlorite, iron(III) chloride, hydrochloric acid or sulphuric acid. In addition, the pumps are equipped with a sensor for hose leaks and a drainage system.


The food version of the PERIPRO peristaltic pump, on the other hand, is optimised for hygiene applications. It is suitable for food, drink and cosmetic

Due to the uniquely large rollers, the pump requires considerably less lubricant. Overall, this results in a saving of 90%, which also simplifies the maintenance of the pump.


It is very important to NETZSCH that all components relevant to the compression of the hose are precisely manufactured. The materials used for hose production are of


products and meets the current standards and regulations. The stainless steel front cover features a window, which can be opened for CIP cleaning processes so one roller can easily be removed. The cleaning fluid can then be flushed through the hose unhindered. ●
