Enter the installation data. The calculator determines TDH and organises compatible pumps by suitability for the duty point.

Beta Indicative results · validate with JOVAL

Sizing support tool. Results are indicative. Maximum flow and maximum head depend on calculated TDH and are not guaranteed at the same time. Validate with the JOVAL technical team.

Input data

Installation setup

Define the water demand and the actual circuit conditions.

Pre-filled 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.
