When it comes to dosing different fertilizers, Spanish filling and packaging specialist Maquienvas was discontent with their electromagnetic and mass flow meters.
They therefore turned to NETZSCH, who recommended PERIPRO® peristaltic pumps specifically for this application that requires handling abrasive, corrosive and organic fluids.
The compact hose pumps fit easily into the filling machine and are pumping the difficult products efficiently and accurately.
For more than 40 years, Valencia-based Maquienvas has been specialising in machinery and equipment for the packaging industry.
Alongside capping machines, labeling systems and complete packaging lines, their wide range of products includes filling machines for different challenging fluids such as fertilisers.
To meet highest product standards and achieve maximum precision in dosing these products, Maquienvas initially utilised electromagnetic and mass flow meters.
However, electromagnetic and mass flow meters are not ideally designed for this application.
The corrosive nature of ingredients like potassium hydroxide and phosphoric acid contained in different fertilisers led to equipment degradation.
The requirement of the product storage tank to be pressurised further increased the risk of leakage as well as maintenance efforts.
As a result, certain components of the dosage system had to be replaced frequently, and overall maintenance costs were relatively high.
Varying physical properties of the fluids, some containing organic particles of up to 1 mm, posed additional hurdles in maintaining consistent flow rates while dosing the fertilizers. These difficulties propelled Maquienvas to seek a more effective and efficient approach – prompting them to turn to NETZSCH, renowned for their innovative fluid management solutions.
