500 Litre Per Minute Bore Pumps

500 Litre Per Minute Bore Pumps

500 litre per minute bore pumps are the FPS-30 range of 6″ Inch bore pumps are available in Three 3 Phase.  They are suitable for 6 inch or larger bore casings.

30m3/h flow rating. 400LPM to 600LPM is the most efficient flow produced by the FPS-30 range.  However, they are capable of flows from 266LPM to 666LPM. Also, capable of heads from 20m to 650m. (see flow chart below)

If you require the FPS30 models such as the 3.7kw in Single 1 Phase 3-wire, please contact us.

Three phase contactors / starters are sold separately and are only available up to 7.5kw.

More pump details and selection advise below the displayed products (at bottom of page).

Each FPS-30 model can produce more or less than 500LPM depending on the head that it is operating at.

All the models on this page are capable of producing from 400LPM to 600LPM efficiently.  They can operate outside that range for short periods of time, but over long periods of time it may shorten the life of the motor. See image below for “Pump Operating Range”.

The amount of water that you get depends on the head that the pump is operating at.

For example, the FPS-30-7 (which is a 9.3kw bore pump), will produce 400LPM when operating at a head of 81m.  This same pump will produce 600LPM if it is operating at a head of 63m. It will produce a lesser flow of 350LPM if operating at a head of 85m.

Bore Pump Selection Hints

Please remember that the ‘Head’ is not just the depth that the pump is set at down the bore casing.  To learn more on how to calculate the ‘head’, please go here: How to Calculate the ‘Total Head’.
