AF, FN, AL and AN families
AF, FN, AL and AN cover different wastewater, effluent and drainage duties. Send the flow, total head, solids, installation arrangement and controls before settling on a model.
Product series
Use the series name to narrow the enquiry, then confirm the exact model, duty and installation from current manufacturer data.
HCP lists vortex, open and channel impeller configurations within the AF family for different wastewater duties.
Before selection: Check the liquid, solids, flow, total head, discharge connection and installation arrangement for the exact model.
The FN family includes several compact sewage and effluent models with model-specific impeller and solids-passage arrangements.
Before selection: Use the full model code and current manufacturer data; limits shown for one FN model must not be applied to another.
AL is a separate wastewater and effluent family which HCP presents with open-impeller configurations.
Before selection: Match the exact model to the duty point, solids, materials, electrical supply and discharge arrangement.
The AN family includes wastewater and sump-oriented models; HCP identifies a shallow-water arrangement for a specific AN variant.
Before selection: Do not apply the shallow-water description to the whole family; confirm the precise suffix and installation detail.
HCP lists stainless-steel hydraulic components and chemical-resistant sealing materials for the SF and SA families.
Before selection: Material names and pH references are not a universal chemical-compatibility approval; identify the actual liquid and concentration.
HCP lists vortex, open and channel impeller versions within the AF family. The exact model still has to match the liquid, solids, duty point and installation.
FN includes different vortex and open-impeller models. AL is a wastewater and effluent family, while AN includes sump-oriented configurations. Do not transfer one model's limits to the whole group.
Send a full data-plate photograph, the discharge connection, controls, fault symptoms and alarm history. Add wider installation photographs only where they are safe to take.
Before a model is chosen
Model capability, materials, electrical data, dimensions and performance must match the exact job. A series name or old model number is not enough on its own.
Send the pump detailsCurrent technical data
Series names help narrow the search. The final choice must use the current manufacturer record for the exact model and UK electrical supply.
