Identify What Is in the Water
Particle size is only one part of the decision. Fibers, sand and sewage may require a different pump design.
WASTEWATER SELECTION
Sewage Pumps
Start with the liquid and solids. Compare the current clean and dirty water range, and identify when the duty requires a dedicated sewage, cutter or grinder pump.

Before You Choose
Before You Choose
Use these points to compare the water, installation and operating requirements before choosing a model.
The models shown here are compact clean-and-dirty-water drainage pumps. They are not presented as cutter or grinder pumps; particle size alone does not establish suitability for fibers, sand or sewage.
Check the Intended Use
The models on this page are compact clean-and-dirty-water drainage pumps. They are not presented as cutter or grinder pumps.
Review the Installation
Share the water, required flow, lift and operating pattern so we can check whether this range fits.
Explore the Applications
For drainage water within the listed models’ limits, explore general drainage and sump drainage. For toilet waste or fibrous sewage, request a separate suitability review.
Key Applications
Where these families may fit within their published limits.
Application suitability depends on the liquid, solids, required duty point, installation/control method and exact product configuration.
Drainage
Screen current clean-and-dirty-water families by liquid condition and documented soft-solids limits before treating the duty as sewage.
Explore applications ↗Basement & flood drainage
Pit and floodwater removal where debris fits documented limits; black-water or sewage duty requires separate pump validation.
Explore applications ↗Construction dewatering
Light dirty-water dewatering only; abrasive slurry and sewage remain separate duties.

Questions to Check Before You Choose
Can these pumps handle toilet waste?
Do not select them for toilet waste from the category name alone. The listed models are drainage pumps for water with soft particles, not dedicated sewage, cutter or grinder pumps.
Does a 25 mm particle limit include sand or long fibers?
No. A soft-particle size limit does not establish abrasion resistance or the ability to handle long fibers. Describe the debris so the pump type can be checked.
