Industry
Municipal Water Supply
Transfer, distribution and booster duties on city water networks, with EN733 and ANSI footprints and a bronze impeller as standard.
Industry Pain Points
What Goes Wrong on These Duties
- Pumps specified to a standard the supplier does not really meetA utility writes EN733 or ANSI B73.1 into the specification for a reason: the next pump has to land on the same baseplate. A pump that meets the curve but not the dimensions creates a civil works problem years later.
- Impellers eroding on raw and potable waterCast iron impellers thin steadily on raw water. The head falls away before anything obvious fails, and the energy cost rises long before anyone opens the casing.
- Pipe class mismatches on imported equipmentA DIN pump arriving on an ANSI network, or the reverse, stops a commissioning programme dead while adaptor spools are made.
- Booster duties at the top of the pressure rangeHigh-rise risers and long distribution mains need a working pressure that a standard 1.2 MPa pump cannot certify.
What Buyers Need
What a Pump Has to Deliver Here
- Pumps that honour the dimensional standard in the specification
- Impeller and shaft materials chosen against the water, not the budget
- Both DIN2501 and ANSI B16.5 flange options from one series
- A published pressure rating for booster and ring main duties

How to Read a Pump Curve
A published envelope such as 2 to 1100 m3/h is a range of sizes, not the capability of any one pump. Here is how to get from it to a selection.

Municipal Water Supply Pump FAQ
Which series suits a municipal distribution duty best?
The FA series in most cases — it publishes the widest envelope, 2 to 1100 m³/h and 2 to 152 m, and offers the 1.6 MPa pressure option that booster duties often need.
Can you match the flange standard already on our network?
Yes. The FA series is supplied with DIN2501 flanges as standard and ANSI B16.5 150lb as an option. The ANSI CN series carries ANSI B16.5 150LB and 300LB.
Why does the FA use a bronze impeller as standard?
Because raw and potable water erodes cast iron. On a series aimed at water supply, bronze is the standard build rather than an upgrade.
Do you hold certifications for potable water contact?
The source catalogue does not publish potable water approvals, so we list none. Tell us which approval your specification requires and we will confirm in writing what can be supplied against it.
