Landustrie Sneek BV

With more than a century of world-wide experience Landustrie has become a leading player in the field of water and wastewater management. Our basis was laid around 1913. The company was active in the agricultural market sector and involved with polder drainage at an early stage. As early as 1916 electrically driven pumping stations were installed with Archimedean screw pumps, together with the countless pumping stations with so-called wind motors. After some time, in addition to the polder drainage pumps, pumps for handling sewage were developed. By the 1950`s this advance opened the way to wastewater purification units being used widely and efficiently. Also research, development and innovation are very important to keep ahead in the present water market. Worth mentioning are our hydropower screw turbines, mobile sanitation units (Mobisan) and dike monitoring systems (DMC).

Landustrie is ISO 9001 certified since 1996. Our QA department certifies that all business processes are being applied according ISO guidelines. In november 2006 Landustrie extended her qualification with EN ISO 3834-2 (formerly known as EN 729-2) in order to meet the quality requirements for welding.

Landustrie is also in the possession of VCA** certification. VCA stands for Veiligheids Checklist Aannemers (Contractors’ Safety Checklist) which guarantees that our employees work according all safety guidelines. The VCA certificate guarantees a structural safety management which will not only reduce the risk of serious accidents but also realise a higher quality. The two star certification (**) means that Landustrie is allowed to work as a subcontractor as well as maincontractor.

All Landustrie products comply with the requirements of CE marking and product directives such as directive of machinery, low voltage directive and electromagnetic compatibility.


An important position is taken by the R&D department which takes care that Landustrie is able to anticipate on new developments in the market. 

As a result of this investment policy Landustrie owns a full-scale test tank in which the Landy surface aerators can be tested. 

Landustrie still is a leading company in the field of aeration technology and in this quality also member of the European Norm Commission for oxygen measurements.


Landustrie developed a fish friendly screw pump based on the existing construction of the Landy screw pump. The screw construction has been adjusted in such way that fish can pass through the screw without being damaged. Most critical points were the entrance of the screw, clearance between trough and blades, and between side rail and blades.


Landustrie's latest screw pump bearing is the Landy Eco-friendly lower bearing, with following features:

  • no maintenance and no grease costs
  • 3-dimensional self-aligning
  • eco-friendly lubricated for lifetime of the bearing
  • no grease pump and grease lines
  • easy to install
  • exchangeable with existing bearings
  • lower investment costs
  • no spare parts required
  • completely enclosed unit


Landustrie produced a new floating unit for their low speed surface aerator, type Landy-7. 

This construction is applied mostly in SBR (sequencing batch reactor) systems and lagoons, in which the water level strongly fluctuates.

Now the new generation of Landy surface aerators can be supplied as a contemporary floating unit. 

With this new design a greater stability during operation of the aerator is achieved. The complete units, aerator with drive unit, are for rent as well.


In order to simulate realistic operating conditions for all constructions designed, Landustrie uses the FEM method (Finite Elements Method). 

This method is especially suitable for strength- and stability calculations.

The main advantage of this method, compared to traditional calculations, can be achieved with aerators, pump impellers, screw pumps, Landox, tanks, vessels, valves, bridges etc.

It is also possible to simulate the dynamic behaviour of a construction
