Xylem Water Systems Australia introduces the latest version of its Hydrovar intelligent pumping control system designed to achieve improved efficiencies and significant energy savings in various pumping applications.

Suitable for use in irrigation water supply, recreational turf watering system, building services or domestic supply needs, the unique Hydrovar by Xylem is a pump mounted variable speed, micro-processor based system controller designed to manage motor speed and match pump performance to a wide range of water industry applications.

Independent tests confirm that compared to full speed pumps, Hydrovar provides energy cost savings of up to 70% by varying the pump performance to match water supply demands.

Featuring a unique wall or panel mounting system, the new Hydrovar variable speed pump controller utilises the output power of the drive to operate a cooling fan, reducing the need for the unit to be motor mounted to operate. With the introduction of a wall mounted fan kit the Hydrovar increases its capabilities for more application types and installations.

The Hydrovar variable speed pump controller package includes the micro-processor, controller, sensor, upgraded management software and a back-lit LCD control panel.

The new wall mount kits are specifically designed to provide the cooling capacity required to ensure longevity of the Hydrovar. The pump controller is available as a Master Drive fully featured for single or multiple pump applications, as a Single Drive with reduced features for a single pump application or a Basic Drive for use on slave pumps in multi-pump applications, or soft start in single pump applications.

Key features of Hydrovar variable speed pump controller:

  • Unique modular design
  • Simple clip-on design allows attachment to the TEFC electric motor of most common pumps
  • Wall or panel mounted alternative makes it ideal for submersible pump installations
  • Easily integrated into existing building management systems
  • Automatically adapts the demand to the pumping system capacity
  • Pump speed adapts to the required pressure and flow ensuring no energy is wasted
  • IP 55 rated housing
  • Multiple failsafe features including low pressure shutdown
According to Con Goltsios, Hydrovar Product Specialist for the Applied Water Systems Division of Xylem Water Systems Australia, there will be significant potential for energy savings especially where there is operation at partial loads of a centrifugal pump. For instance, in a multi pump application in building services or recreational turf watering systems, the Hydrovar will automatically shut down one or more pumps when demand falls, resulting in power savings.

Hydrovar’s seamless multiple redundancy feature is a major advantage in multi-pump installations with one of the other drives automatically taking over control of the system in the event of a pump or drive failure, ensuring constant water supply.
