JOVAL engineering · Made in Portugal

Hydraulic Calculator

Pre-size the installation, calculate Total Dynamic Head (TDH) and identify JOVAL pumps compatible with the duty point.

Installation data and hydraulic selection

Installation data and hydraulic selection

Enter the actual circuit conditions. The calculator determines TDH and ranks compatible pumps by fit for the duty point.

Installation data

Enter the water demand, elevation and pipework.

Use example:
System parameters
Filters recommendations by installation type before comparing hydraulic curves.
m
Vertical distance from surface to dynamic water level.
m
Additional height between the borehole/source point and the house, tank or discharge point.
bar
Desired pressure at the point of use. 1 bar is approximately 10.2 m of water column.
m³/h
Volume of water needed per hour. Coverage is up to 350 m³/h, depending on calculated TDH.
Convert other flow units
Helps avoid unsuitable recommendations when sand or special water conditions are present.
Usage context is included in the technical request so the selection can be validated.
mm
Optional. Filters pumps whose body does not fit the specified borehole.
Filters families that are clearly incompatible with the available power supply.
m
Total pipe length (vertical + horizontal).
Internal diameter. Auto-selected based on flow rate.

Pre-sizing result

TDH, pipe velocity and compatible pumps will appear here.
