Xylem 5th generation HYDROVAR intelligent pump control system

Xylem has released the 5th generation HYDROVAR, an intelligent control system that adapts to system demands. The drive and motor control can reduce the energy consumption of a pump by as much as 70%, according to the company.

Capable of running systems with up to eight pumps, the product has multimaster functionality, enabling each individual pump to take control if one or more units or sensors are not active. This continuous booster system operation ensures stable water pressure across various applications.

The product is backward compatible to the current-generation HYDROVAR and is designed to accommodate both new and retrofit installations. A wiring harness includes a separated wiring chamber with a dedicated cover that provides safe and easy access to the wiring while protecting the unit’s electronic components. The clip-and-go mounting system simplifies the direct fitting process.

The start-up menu guides users through the commissioning process, while the large LCD display shows an expanded range of system parameters for standard motors. This functionality enables installers to manage a wide range of data.

Wear and tear is minimised due to features such as advanced motor control software, which extends the life of the equipment by reducing heat. The unit also has an embedded current total harmonic distortion (THDi) filter that lengthens overall life of the equipment connected to the same grid and prevents cables from overheating.

Using the product with an existing pump can lead to significant energy savings, especially when operating at partial loads. It can be retrofitted to any standard asynchronous pump motor suitable for variable speed operation. The direct mounting method does not require a special adapter and is available for power ranges from 0.55 to 22 kW.

The modular design enables a customised fit for any configuration of pumps, and the product can be motor- or wall-mounted for use with any manufacturer’s pump. Configuration options range from a single pump to as many as eight pumps to meet any application requirement.
