Submersible Sewage Pumps with Cutter Blade
A grinder submersible pump is a wastewater pump whose rotating blade at the inlet cuts fibres, rags and solids into small pieces and pumps them through small-bore pressure lines without clogging.
It is used on long pressurised wastewater lines, villa and facility septic tanks, hotels and campsites. The product range includes 1.1–1.5 kW models and stainless-bodied versions.
Main Applications
- Long pressurised wastewater lines
- Villa and facility septic tanks
- Hotels and campsites
- Basement toilet waste
- Small lift stations

Which material? A grinder pump can lift over long distances through a small-bore pressure line; blade wear accelerates in water with sand and stones. For grinders, flow and head are fixed by the chosen model.
