Series Datasheet
The published specification for a chosen series: construction, design standard, size range, operating envelope and material options.
Request by emailDocumentation is issued against a stated duty rather than published as a generic download, because the specifications that matter differ with the size and the liquid.
We do not publish blanket PDF downloads. Several specifications across the range are not published in the source catalogue at all, and issuing a document that filled those gaps with estimates would be worse than issuing nothing.
Instead, tell us the series and the duty and we will send the documentation that actually applies to it. Everything listed below is available on request by email.
There are no blanket PDF downloads on this site. Several specifications across the range are not published in the Flowsteer catalogue, and a generic document would have to omit them or fill them with estimates. Documentation issued against a duty can confirm them properly.
The published specification for a chosen series: construction, design standard, size range, operating envelope and material options.
Request by emailThe specification narrowed to the size selected for your duty point, with any TBC values confirmed in writing.
Request by emailMounting and connection dimensions for a selected size, for checking against an existing baseplate or a new layout.
Request by emailThe wetted material specification for a chosen build, confirmed against the water analysis you supply.
Request by emailWritten confirmation of the flange standard and rating for a selected pump against your installed pipe class.
Request by emailInstallation, commissioning and maintenance guidance for the selected series. The guides on this site cover the general engineering; this is the series-specific version.
Request by emailA check of an existing pump's size designation and flange rating against the Flowsteer range, for like-for-like replacement.
Request by emailConfirmation of what performance test documentation can be supplied with an order.
Request by emailThe general engineering behind the range is published openly. Only the series-specific documentation is issued per enquiry.

B73.1 is a dimensional standard, not a performance standard. Knowing the difference is what makes a replacement pump drop straight onto an existing baseplate.

One standard says where the holes go. The other says how long the pump should last. Specifications usually need both.

Two names, one set of dimensions. Why both still appear on specifications and what they fix on an end-suction pump.
Read more
The single construction feature that decides whether a seal change takes two hours or two days.
Read more
Efficiency on one side, solids passage and adjustability on the other. The choice is decided by the water, not the pump.

Grey iron through to UHMW-PE. What each wetted material is for, and the failure it is chosen to prevent.

The series you are interested in, and ideally the duty point. With the duty point the datasheet can be narrowed to the size that actually applies.
Yes, in writing, against the size selected for your duty. That is the main reason documentation is issued per enquiry rather than published as a blanket file.
Dimensional information is issued on request against a selected size. Tell us what format your project needs when you ask.
Documentation comes back narrowed to the size that actually applies, with any TBC values confirmed in writing.
