Landia chopper pumps
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.
Energy efficient mixing
Landia has been manufacturing mixers since 1970 when a need arose - first within agriculture and later in wastewater treatment plants. Thousands of Landia mixers have since been sold around the world, where on a day to day basis they contribute to the optimal operation of wastewater treatment plants, biogas plants, agriculture and many other industries where there is a need for effective and energy efficient mixing of fluids.
As a Danish company, it is natural that Landia over the years has developed mixers with the lowest possible energy consumption. Mainly, low energy consuming mixers have the lowest propeller speeds as possible. This not only saves energy, but it also leads to increased life span of the product with the lowest maintenance cost.
Landia has the largest selection of submersible and dry mounted mixers with countless variations and motor sizes, ranging from 1.1 to 30 kW. Landia mixers are always adapted to the specific task and are supplied in the materials that provide the longest lifespan - whether it be cast iron or acid proof steel.
The operating conditions for a mixer are often extreme, which places great demands on the sealing system. Landia has developed a unique sealing system consisting of three or four seals in combination with a grease chamber. This is unique in the global market!
A mixer is a special product which can only be sold under expert guidance - guidance which naturally is included in every Landia product.
AirJet - systems to aerate and mix difficult mediums when treating sewage, storm water, industrial effluents and agricultural waste.
The benefits of the Landia AirJet aeration and mixing systems are created by the
unique concept of combining a highly efficient air ejector with chopper pumps,
and may also be used in conjunction with supplementary mixing systems,
for optimum oxygen transfer rate.
As a world leader, Landia offers below surface aeration and mixing technology combined with chopper pumps. Combining chopper pump aeration systems with Landia submersible mixers provides the most beneficial approach to energy efficient and customized solutions even when treating the most difficult mediums.
