Industry
Industrial Water Transfer
Plant water, process circulation, booster and liquid transfer duties across the full Flowsteer size band.
Industry Pain Points
What Goes Wrong on These Duties
- A pump population that grew one purchase at a timeFive brands in one plant means five spares kits, five sets of drawings and five suppliers to chase.
- Duties spread from DN 25 to DN 400Few series cover both ends, so most sites end up with a small-pump supplier and a large-pump supplier.
- Process water chemistry that changes with the processA material specification written for one product run may not hold for the next.
- Maintenance windows that keep getting longerEvery seal change that needs pipework broken adds hours that the production schedule does not have.
What Buyers Need
What a Pump Has to Deliver Here
- One hydraulic family across the whole size band
- Metal and polymer wetted parts available within the same catalogue
- Back pull-out construction to shorten maintenance windows
- A supplier who will state what is unconfirmed rather than guess

NPSH and Cavitation
Cavitation is not a pump defect. It is a suction system defect that destroys the pump, and it is almost always designed in rather than developed.

Industrial Water Transfer Pump FAQ
Can one supplier really cover DN 25 to DN 400?
The DE series is published across that band and the other four series overlap it, so most industrial water duties on a site can be met from one catalogue.
How do I decide between metal and polymer wetted parts?
By the water analysis and the temperature. If the chemistry attacks iron and stainless, the KCP series in PP, PE or UHMW-PE is the answer; if it does not, the metal series give higher flow, head and temperature.
What does back pull-out save on a maintenance window?
The pipework stays bolted to the casing, so flange breaking, re-gasketing and pipe re-alignment all disappear from the job. What remains is uncoupling the driver and withdrawing the rotating assembly.
Why are some specifications marked TBC on your product pages?
Because the source catalogue does not publish them. We would rather mark a value unconfirmed than print a number we cannot stand behind, and we confirm it in writing at enquiry.
