Hydrovar Energy Calculator

Use this tool to approximate energy savings with a Hydrovar Controller compared to a full speed pump.

Following data is to be entered for the calculation:

Step 1 – Select the unit you want to use for pressure

Meter Bar

Step 2 - Enter the common operating conditions

  • Enter up to five common flow rates required by your system,
    starting with the highest flow.
  • For each flow, enter the TDH of a full speed pump at that flow rate.
  • For each flow, enter the percentage of total time the pump runs at this flow.
  • For multi-pump systems, apply the percentage of full capacity to the flow rate of the first pump.
Flow rates cu.m³/h TDH at Max % of total time
   

* Enter data in all boxes.
** Program assumes pumped liquid is water.

Step 3 - Enter the maintained pressure

Bar = Enter the pressure to be maintained in Bar.
Bar = Enter suction pressure if any in Bar.
m³/h =
Eff. =

* Enter data in all boxes.
** Program assumes pumped liquid is water.

Step 4 - Enter the energycosts

Enter your average energy cost per kilowatt hour.
(local currency)

The result of the calculation

Based on the data supplied, a Hydrovar equipped pump will result in the following savings:

For a Hydrovar equipped pump:

Kilowatt Hours per year for full speed pump:  
Cost per year for full speed pump:  
Kilowatt Hours per year for Hydrovar pump:  
Cost per year for Hydrovar pump:  
Annual energy savings with Hydrovar:  

For Multiple Pump Systems Running in Synchronous Mode:
