Dosing pumps
Doseuro designs and produces advanced metering and dosing pumps for chemical, acid, or basic liquid products. The range offers excellent solutions for reliability and precision, guaranteeing constant performance over time for critical applications in over 70 countries worldwide.
Dosing pumps for viscous and corrosive fluids
Systems for process liquid handling
The technological proposal of FPZ includes metering pumps with diaphragm and piston designs, engineered to manage variable flow rates with extreme volumetric accuracy. For applications requiring low flow rates, the electromagnetic dosing pumps offer high operational flexibility regulated by an integrated microprocessor. The use of high-resistance wetted materials, such as AISI 316L, PVC, PP, and PVDF, ensures full chemical compatibility and correct management of liquid viscosity in complex industrial contexts. Flow rate adjustment can be performed manually or via advanced protocols such as MODBUS and PROFIBUS.
FPZ dosing pumps comply with the API 675 standard
Thanks to a fully oil-bath lubricated worm gear mechanism, the positive return units are engineered to meet the rigorous performance requirements of the API 675 standard, 3rd edition.
The FPZ range includes dosing pumps suitable for ATEX environments
Operational safety in explosion-risk zones is guaranteed by the availability of ATEX dosing pump configurations. From piston to hydraulic diaphragm versions, every component is validated to operate in potentially explosive atmospheres, ensuring full regulatory compliance in the petrochemical, mining, and pharmaceutical sectors.
Our range includes high-pressure dosing pumps
We develop high-pressure dosing pumps (AP configurations) capable of reaching operating pressures up to 250 barg. These solutions are specifically designed for the injection of additives and reagents under high back-pressure conditions, maintaining the volumetric stability necessary for correct liquid dosing pump performance in upstream and downstream Oil & Gas applications.
Discover the hermetic seal of our hydraulic diaphragm metering pumps
FPZ hydraulic diaphragm metering pumps guarantee a total "zero leakage" hermetic seal. The version with a sandwich hydraulic diaphragm integrates a rupture detection system, making it the optimal technical solution for handling toxic, corrosive, or radioactive fluids where no environmental contamination is permitted.
Motors certified according to international standards
Each unit involved in dosing pump manufacturing is equipped with high-quality electric motors compliant with IEC and NEMA standards. Special motorizations are available with different voltages, frequencies, and insulation classes, as well as special explosion-proof executions, to ensure the electromechanical integrity of the system in any global industrial power network.
Discover how you can reduce startup times
The adoption of advanced digital interfaces and inverter motors optimizes commissioning procedures. The dedicated priming mode facilitates air expulsion and rapid priming of the pump body, minimizing machine downtime and simplifying maintenance and integration operations into pre-assembled systems.
