Longer service life, fewer failures: the value of hydrovar® X for OEM systems
by Michael Somma, Factory Application Engineer, OEM
OEMs operate in an increasingly complex and competitive context: they must guarantee reliable, efficient, and easy-to-manage systems, responding to demands for operational continuity, reduction of maintenance costs, and energy optimization. Every machine downtime is not just a technical problem, but generates economic impacts, delivery delays, and risks to the reputation of customers. Furthermore, the growing complexity of systems and sustainability expectations impose solutions that combine high performance with intelligent resource management.
In this scenario, Xylem's hydrovar® X represents a concrete answer: an integrated solution that combines an IE5 assisted reluctance motor and inverter into a single compact system, designed to support OEMs in overcoming daily challenges, improving performance, protecting components, and minimizing the risks of system downtime.
Intelligent speed management and fault protection: less maintenance, more reliability
One of the most immediate aspects of hydrovar® X is the intelligent management of speed. The pump no longer works constantly at maximum speed, but modulates its operation based on the real demand of the system. This approach reduces vibrations and mechanical stress, decreases wear on bearings and mechanical seals, extends the service life of the pump, and limits the need for extraordinary maintenance interventions. In e-SV vertical multistage models, hydrovar® X further enhances constructive robustness thanks to components designed to last, such as balanced seals and high-performance anti-wear materials, guaranteeing reliability even in the most demanding operating conditions.
hydrovar® X also works "behind the scenes" to protect the system from potential electrical anomalies. Overloads, voltage peaks, overheating, or phase losses are detected and managed automatically, safeguarding the motor and pump. The integrated diagnostics, clear and detailed, provide specific error codes that allow for rapid and targeted interventions, minimizing downtime and guaranteeing operational continuity.
A further advantage is the predictive capacity offered by connectivity with Avensor, Xylem's IoT platform. Thanks to this technology, it is possible to analyze historical data and operating trends, receive preventive alerts, and plan maintenance interventions proactively. In this way, system management moves from a reactive to a preventive approach, increasing the overall reliability of the system and supporting OEMs in guaranteeing higher service levels to their customers.
Energy efficiency and multi-pump management: optimal performance for complex OEM systems
From a performance perspective, hydrovar® X combines an IE5 motor and drive with IES2 efficiency, ensuring stable pressure, immediate adaptation to load variations, and multi-pump management of up to eight units in complex configurations. This makes the solution ideal for modern applications and articulated systems, where precision, continuity, and energy optimization are fundamental requirements. By adjusting the speed according to the real demand, the pump consumes only the necessary energy, reducing operating costs and environmental impact and guaranteeing a rapid return on investment.
In short, hydrovar® X is not simply an inverter, but a new approach to pump management: more efficiency, greater protection, and operational continuity. For OEMs wishing to integrate reliable, modern, and competitive solutions into their systems, hydrovar® X represents today one of the most evolved options in the Lowara range, capable of responding to the needs of complex systems and the most advanced applications.
