Chopper/sludge pumps (submerged) for wastewater

The DG-I pump is a series of submersible pumps, which are developed to pump heavily polluted wastewater and sludge with a high dry matter content. All DG-I pumps are fitted with a knife system at the pump inlet. The knives ensure smooth operation in conditions where many other pumps have problems with clogging.

Let us find a solution together

Use of the wastewater pump

The submersible chopper pump has several wastewater applications. As an example, the DG-I pump has proven to be a problem solver in pumping stations, where there is a large content of rags, wet wipes and other debris that would typically cause other pumps to have trouble operating. 
Landia’s pumps are designed to be able to pump liquids with high viscosity. This makes them extremely suitable for pumping wastewater sludge. For use in liquids that contain abrasive particles such as sand, we have developed specialty materials that can significantly extend the service life of the pump compared to a standard pump, resulting in lower long-term operating costs. If the pump is to be operated in more aggressive liquids, such as wastewater from dairies, we offer the pump in stainless steel.
