General engineering orientation to help you specify and enquire with confidence. Guidance only — selection, configuration and scope are confirmed against your project specification at quotation.
Centrifugal pump families
Most industrial duties are served by centrifugal pumps, which convert rotational energy into flow and pressure through an impeller. The families below differ in casing arrangement, suction configuration and stage count, which determine the duties each suits best. Selection is confirmed against the specified duty point at quotation.
End-suction pumps
The most common general-duty configuration: a single impeller with an axial suction inlet and radial discharge. Simple, compact and economical for water transfer, building services and general industrial process duty.
Horizontal split-case pumps
The casing splits along the shaft axis, allowing the rotating element to be lifted out without disturbing pipework. Double-suction impellers balance axial thrust, suiting higher flows in water supply, district energy and fire-water duty.
Vertical inline pumps
Suction and discharge sit on a common vertical axis so the pump installs directly in the pipe run, saving floor space. Widely used in building services circulation and pressure-boosting.
Multistage pumps
Several impellers in series raise head beyond what a single stage can deliver economically. Used for pressure boosting, boiler feed and reverse-osmosis feed duties.
Self-priming pumps
Designed to evacuate air from the suction line and re-prime after shutdown, suiting duties where the pump sits above the liquid level, such as tanker off-loading and sump duties.
Submersible and sewage pumps
The motor and hydraulic end operate submerged in the pumped liquid. Solids-handling impellers (vortex, channel or cutter types) suit sewage and drainage duty.
Side-channel pumps
Side-channel hydraulics handle low flows at high heads and tolerate entrained gas, suiting condensate and volatile-liquid duties where conventional centrifugal designs would lose prime.
Preparing a pump enquiry
- Duty point — flow rate and total head
- Fluid, temperature, solids or viscosity
- Suction conditions and NPSH available where known
- Preferred configuration or installation constraint
- Power supply and drive arrangement
