DE Water Centrifugal Pumps
The DE process pump: developed from introduced process-pump know-how, sized DN 25 to DN 400 for water and waste water service.
Explore the rangeThe Problem
What This Category Is For
Most plants end up with five pump brands because each new duty was bought on its own. The general water pump family exists to reverse that: one hydraulic philosophy from the smallest auxiliary duty to the largest transfer duty, so a standardisation programme can actually be finished.
Who It Suits
- Plant engineers consolidating a mixed pump fleet
- Water and waste water operators needing small and large pumps together
- Buyers who prefer one supplier across the whole size band
- Sites planning standardisation over successive maintenance cycles
Problems It Solves
- Pump populations that grew brand by brand
- Spares stores expanding with every new purchase
- Separate pump types for clean and waste water
- Capacity ceilings that force a second series

Advantages
Why This Category Is Built the Way It Is
- DN 25 to DN 400The widest size band of any Flowsteer series.
- Flow to 600 m³/hEnough for main transfer duties without moving to a split-case pump.
- Water and waste waterOne construction covers both services.
- Process-pump heritageThe series was developed from introduced process-pump know-how rather than scaled up from a domestic water pump.
Typical Application Scenarios
- Tank-to-tank transfer across a plant
- Waste water service on a general-purpose duty
- Sites needing DN 25 and DN 400 pumps from one family
- Phased replacement of a mixed fleet

Water Centrifugal Pumps FAQ
What is the size range?
DN 25 to DN 400, with flow up to 600 m³/h — the widest band in the Flowsteer range.
Why are head and materials shown as TBC?
Because the source catalogue does not publish them for this series. We mark unconfirmed values rather than print a figure we cannot support. Ask and we will confirm for the size you need.
Can one series really cover DN 25 to DN 400?
Dimensionally and commercially, yes, and that is the point of it. Hydraulically each size still has to be selected against its own duty point.
Is the DE suitable for waste water?
Yes, the series is specified for water and waste water application. Tell us the solids loading so we can check it against the KCP and VNP series.
Specify a 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.
