Landia developed their first chopper pumps in 1950. A chopper pump is a pump with rotating knives at the inlet of the pump, - a knife system which ensures that the pump does not stop due to impurities in the fluid being pumped.
Originally, Landia's chopper pump was designed to chop straw, which was always present in liquid manure and gave rise to breakdowns and problems.
Landia chopper pumps are still used extensively for pumping liquid manure but over the years have also won recognition for their excellence in other industries where there is a need for trouble-free pumping of e.g. untreated wastewater, sludge, liquid biomass, by-products from the food industry or highly abrasive fluids.
Most of Landia's chopper pumps can also be obtained in acid proof steel for pumping fluids with low or high pH.

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.
