\ud83d\udd27 Precision at Low Flow Rates: Dosing DEMINERALIZED WATER with WLX External Gear Pumps
\nAt Pompe Cucchi, we continue to push the boundaries of precision and control in volumetric pumping. One of the most delicate challenges in industrial applications is the accurate dosing of DEMINERALIZED WATER, especially when flow rates are extremely low and system pressure is significant.
\nToday we are testing our WLX external gear pump for an application requiring the dosing of DEMINERALIZED WATER at 30 liters per hour and 7 bar of pressure. This case perfectly illustrates the capabilities and reliability of our gear pump technology, even in the most sensitive processes.<\/p>\n
\ud83d\udca1 Why is DEMINERALIZED WATER dosing a technical challenge?
\nUnlike many viscous or lubricating fluids, Demineralized Water presents specific difficulties:
\nLow lubricity
\n\u2013 DEMINERALIZED WATER has little to no lubrication properties, which increases wear risk on standard pump materials.<\/p>\n
Corrosive potential
\n\u2013 Although it’s “pure”, DEMINERALIZED WATER can be aggressive to metals due to its high affinity for ions. Special material selection is crucial.
\nFlow stability at low rates
\n\u2013 Operating at just 30 l\/h demands extremely tight clearances and high mechanical precision to avoid pulsation and leakage.
\nSystem pressure
\n\u2013 With discharge pressure up to 7 bar, the pump must ensure perfect sealing and dimensional stability, even under stress.
\n\u2699\ufe0f The WLX Advantage
\nThe WLX Series of external gear pumps has been developed by Pompe Cucchi with these challenges in mind:
\n\u2705 High precision machining for micro-dosing
\n\u2705 Advanced materials for handling non-lubricating and aggressive fluids
\n\u2705 Compact, modular design for seamless integration
\n\u2705 Excellent repeatability and minimal pulsation
\nIn this specific project, the WLX pump delivered continuous, accurate dosing of DEMINERALIZED WATER, with stable performance over time and no leakage or premature wear, thanks to careful design and optimal materials selection.
\n\ud83e\uddea Conclusion
\nDEMINERALIZED WATER may seem like a simple liquid, but dosing it reliably under pressure and at low flow is anything but simple. It requires a pump that is:
\nRobust yet delicate,
\nPrecise yet durable,
\nAnd above all, engineered for long-term consistency!<\/p>\n","protected":false},"excerpt":{"rendered":"
