Water & Wastewater New generation with improved multipump capacity

Enhanced multipump capability Here’s what the industry has been waiting for – the next generation Flygt Hydrovar that offers even greater exibility. Up to 8 Hydrovar pumps can be connected to one system in a multi-controller mode. We’ve taken pumping to a new level of efciency, too, with energy savings up to 70%. 12 0 50 0 25% Q[m³/h] 100 150 P [kW] 10 8 6 4 2 0 2 50% 75% 100% The software structure has been enhanced, too. The illuminated display permits easy handling and programming, even in difcult situations. 200

So much more The new generation Flygt Hydrovar concept means you only pay for what you really need. It’s easy to integrate into a BMS system, and Modbus communication is standard. Hydrovar supports various types of sensors because of an enhanced input signal range (4-20mA, 0-20mA, 0-10Vdc). There are two sensor inputs for implementing two actual value signals within one system– min/max, difference. Or for a second sensor for safety reasons. Available Hydrovar versions include Single and Master. 3

Single inverter Only one Flygt Hydrovar Master unit is needed for controlling up to 5 fixed speed pumps in the cascade relay mode. While as many as 8 Master Hydrovar pumps can be connected to The extended manual control mode has different fixed speed values that are changeable with an external contact. Hydrovar features pro- grammable output signals, too-analogue out/digital out. As you would expect, retrofitting is possible for all existing standard asynchronous motors that are suitable for VFD operation.

Additional features the Hydrovar unit means simple, fast and inexpen- sive retrofitting of existing Flygt Hydrovar performance is automatically adjusted to varying de- mands. All hydraulic control functions are included, which means addi- tional external controllers are not required. The motor fan optimizes cooling, depending on the power and speed of the pump itself. And, of course, maintenance intervals are longer be- cause of less stress to the pump and motor. all existing standard asyn- chronous motors, which Constant system pres- sure in water supply along the system curve All...

Energy-efcient – new standard for the new generation 6

Signicant energy savings of up to 70% are possible with the new generation Flygt Hydrovar. This is particularly the case when a centrifugal pump is running at partial loads. For instance: By operating a closed loop HVAC system in accordance with system curve compensation, you are lowering the required pressure in the system. This reduces speed/power required from the pump and can result in energy savings of up to 70%. Example: Circulation pump with nominal power in partial load operation. Capacity in % Power consumption as per curve Saving in kW Saving per 1/3 year (2.920 h) Pump at const....
