Landia’s pumps are well suited for different applications within wastewater. For example, our submersible pump DG-I has proven to be a problem-solver in pumping stations containing wet-wipes and similar items causing problems for the existing pumps. All Landia pumps are equipped with a knife system by the pump inlet. This ensures hassle-free operation in conditions that cause clogging in other pumps.


The open pump impeller design enables Landia’s pumps to handle liquids with a high viscosity, such as sludge with a high dry-matter content.


For liquids containing abrasive particles, such as sand, Landia has developed special materials that prolong the service life of the pump in comparison with a standard pump. A large part of Landia’s pump portfolio can be delivered in acid resistant steel for aggressive liquids with a high or low pH value.


Generally, Landia pumps take over where other pumps give up because of clogging, high viscosity or wear and tear.

The Chopper Pump celebrates its 70th anniversary in 2020


When Landia’s founder, Christian Oelgaard, invented the Chopper Pump in 1950, he was determined to solve the problem of clogging manure pumps on dairy farms.
He succeeded - and the World’s first chopper pump was born.


Christian was a forward-thinker, but even this distinguished pioneer might not have foreseen how widely the chopper pump would be used today, 70 years later. Manure pumping is still a big item but solving clogging problems in raw sewage has become the modern-day task for the chopper pump. Equipped with a unique hardened steel chopping system, the Landia Chopper Pump makes light of modern-day nuisance waste, such as wet wipes, that bring lesser pumps to a clogging, grinding halt.


Christian Oelgaard knew that standard pumps could only pump standard waste, so he invented the Chopper Pump to take care of the really tough applications. The Landia chopper pump is widely used for pumping digester sludge, clarifier scum, food waste, and a wide variety of other municipal and industrial waste streams.
