Which borehole pump series
should you look at first?
Use this to find the right catalogue section. The model still needs to be checked at your required duty.

A flow group is a catalogue reference, not a guarantee of flow at any head. Impeller material does not describe every component or establish suitability for saltwater or corrosive liquids.
Prepare for selection
Borehole depth is not
the same as total head.
Account for the lift from the pumping water level to the delivery point, pipe losses, and any pressure required at the outlet. The drilled depth alone does not describe that duty. If you only know the well depth, include it—but say which other measurements are still missing.
- 01
Define delivery demand
Target flow and the required pressure or tank elevation.
- 02
Describe the well
Internal diameter, dynamic water level and intended setting depth, if known.
- 03
Confirm the supply
Voltage, phase and frequency, plus the required control function.
Common borehole
pump questions
Is the model prefix the minimum borehole diameter?
Use the confirmed maximum assembly diameter and the installation clearance. A model name or a motor diameter alone is not enough to define the minimum borehole size.
Can a PM pump use any inverter of the same power?
The drive must support the specific motor type and its operating requirements. Confirm the pump, motor and drive as a matched configuration.
Can I order a pump with controls and accessories?
List the required components with your enquiry. The quote should identify the included pump, drive, cables, fittings, sensors and service parts separately.
A little help goes a long way
Not sure which detail matters?
A short description, an existing model or a photo gives us a starting point. Our team can help with the next questions.
