The Problem
What This Category Is For
A water pump scaled up from a domestic design behaves differently at DN 400 than it did at DN 50. The DE was developed the other way round, from process-pump practice, which is what lets one series hold together across a sixteen-fold range of nominal bore.
Who It Suits
- Engineers who care where a hydraulic design came from
- Plants running one series across a very wide size band
- Buyers standardising spares logic rather than part numbers
- Operators handling both clean water and waste water on one design
Problems It Solves
- Designs that do not scale cleanly across the size band
- Two pump types where one would do
- Spares logic that changes with the pump size
- Suppliers who cover only part of the range
DE series centrifugal pump coupled to a flange motor on a fabricated baseplate
Advantages
Why This Category Is Built the Way It Is
- Process-pump design originDeveloped by introducing foreign advanced process-pump know-how.
- Sixteen-fold bore rangeDN 25 to DN 400 on one hydraulic philosophy.
- Flow to 600 m³/hCovers main transfer duties within the series.
- Dual serviceWater and waste water from the same construction.
Typical Application Scenarios
- Process water transfer on an industrial site
- Waste water duties within a general plant population
- Small auxiliary pumps sharing a family with large transfer pumps
- Long-run standardisation across a site

DE Water Centrifugal Pumps FAQ
What does DE stand for?
DE is the Flowsteer series designation for its general-purpose process-duty water pumps, covering DN 25 to DN 400.
What does 'introduced know-how' mean in practice?
The source catalogue states the DE was made by introducing foreign advanced process-pump know-how. It means the hydraulic design came from process-pump practice rather than from a scaled-up domestic water pump.
What flow can the DE reach?
Up to 600 m³/h, with the size band running DN 25 to DN 400.
How do I get the specifications marked TBC?
Send us the duty point and the water analysis with your enquiry and we will confirm head, speed, materials and sealing in writing for the size selected.
Specify a DE Water Centrifugal Pump for Your Duty
Send the flow, head, supply frequency and liquid description and we will confirm the size and the published specification for it.
