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.
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.
Case study about chopper pumps
Landia chopper pumps make it nuuk clear in Greenland
In Greenland’s capital city, Nuuk (population approximately 17,500), pumps made by Landia have solved a troublesome clogging situation at an important pump station.
Our models
Landia manufactured the Worlds’ first Chopper Pump in 1950, and today it is used in a wide range of applications in industries such as wastewater treatment, food processing, pulp and paper, bioenergy, aquaculture, oil and gas, etc.
The rugged design of the Landia chopper pump gives you a superior choice for the most challenging applications.
You get a pump that never gives up.

Our solutions within wastewater
Sewage lift stations
The Landia’s chopper pumps break down impurities before they are pumped further into the system and therefore act as a problem solver in pumping stations.
Pumping sludge
Landia can offer durable pumping solutions for pumping all types of sludge.
Aeration, jet aerators
The Landia AirJet is an ejector aerator that works by aspirating the air into the ejector and subsequently mixing it with the wastewater during combined mixing and aeration.
