Water is a vital source of life and exists all around us. Landustrie activities and products revolve around it. Landustrie have the expertise and capabilities to provide solutions for every segment in the water chain. Landustrie has been active in the water technology sector for more than 100 years
Landustrie Sneek BV Products
Wastewater treatment
For the municipal and industrial market, Landustrie designs and supplies equipment that can be found in every phase of wastewater treatment process, from Archimedes screw pumps to screen cleaning equipment and aeration systems. Landustrie has extensive knowledge and experience, and a strong track record in the field of wastewater treatment. This gives Landustrie the opportunity to design the most optimal aeration systems and to implement the most efficient aeration configuration. We also recognize that innovation in wastewater technology is of utmost importance. Main issues are how to reduce energy consumption and contribute to a circular economy. This has led to new innovative sanitation solutions such as decentralized wastewater treatment, resulting in the regeneration of valuable material, and residues that are reused for energy production.
Pumps
The philosophy behind the design of our wastewater pumps, both submersible and dry-installed, is quality, simplicity, durability, and low maintenance needs. Our goal is to maximize your investment returns with the minimum environmental impact, while providing a robust product that is tailored to your needs. These basics are what you will find in all products that are built and tested in our workshops in Sneek. Since wastewater can be contaminated with different materials and chemicals, Landustrie can supply the pumps in a wide variety of materials and with the necessary certifications. For you as our customer, Landustrie‘s goal is to fulfil your pump challenges in a satisfying way. For selecting the most efficient pump we offer our LANDY-Sel pump selection program. Using a clear interface with basic questions the program guides you to the best selection. Pipework and friction loss calculations are also covered in the program along with the individual data sheets for all pumps. Before shipment, all LANDY pumps are checked hydraulically in our own test facility, prior to shipping. A witnessed test certificate is available. All pumps are supplied with an unique serial number and test curve.
Manufacturing
To ensure the absolute highest quality product, we manufacture all of our LANDY products at our factory in Sneek, the Netherlands. At our 15.000 m2 state-of-the-art manufacturing facility, we have all of the latest technology to manufacture and assemble products of various materials. Each step of the manufacturing process is performed under our roof and more importantly, under our quality control programs. Our end products meet the standards set by Stoomwezen, Lloyd’s Register, Germanischer Lloyd, DNV, ABS and WSA.
High Efficiency Surface Aerator
In the field of surface aeration Landustrie has a long history and broad experience.
Landustrie designs, manufactures, supplies, installs and maintains many types of aeration systems, with either surface aerators, aeration rotors, diffusers and Landox flow boosters.
Since the introduction of our own full-scale aeration test tank and the availability of substantial process know-how, Landustrie is a leading player in aeration technology. In our test rig the characteristics of our Landy aerators are constantly researched. With these test facilities an optimal aeration selection can be realized.
Testing possibilities :
- oxygenation capacity
- power consumption and starting current
- efficiencies
- axial and radial forces
- vibration and noise level
- flow velocities
Also a special toolbox has been developed for checking the functioning of surface aerators in relation to actual load. Savings achieved with this aeration scan can be as much as 30 %.
Landy surface aerators are characterized by the following features:
- high and constant efficiency
- extreme low reaction forces
- excellent mixing qualities
- simply regulated
- wide oxygenation range
- wide range of applications
- simple and robust construction
- self cleaning
- low maintenance costs
The efficiencies that can be obtained with low speed aerators depend on a number of factors. One important factor is the geometry of the basin in which the aerator will be installed. The Landy aerator can be installed in either a fixed or a floating arrangement. Regarding the geometry of the basins the options are virtually unlimited: square or rectangular tanks, round tanks, shallow or deep tanks, oxidation ditches, MBR- and SBR systems, lagoons, ponds, mixing or buffer tanks.
Archimedes Screw Pumps
With a fully automated screw pump selection program the optimum screw pump can be chosen for any particular application.
Applications:
- influent pumping stations
- intermediate pumping stations
- return sludge pumping stations
- irrigation projects
- drainage projects
- reclamation of wetlands (polders)
- wild water tracks in fun parks
- industrial applications
- storm water applications
- hydropower scheme
As the screw pump can be applied in different fluid environments from clean to high grit or acidic conditions material selection is crucual to ensuring a long trouble free life time. Landustrie is able to apply different materials and coatings to guarantee trouble free operation in virtually all water conditions, for the years to come.
Features of Landy screw pump:
- fish-friendly
- durable and trouble free
- high efficiency
- wide working range
- low operation costs
- quiet and protected
Screw troughs are available in several options, varying from concrete to steel, with casting mould, fully self-supporting or tube trough. The same applies to our lower und upper bearings, f.i our Landy Eco-friendly lower bearings with water-in-oil detection, which are zero maintenance in operation.
Pumping
Vortex pumps are used for sewage and wastewater treament. Our LANDY Vortex pumps are renowed for their outstanding non-clogging performance and designed to pump a wide variety of solids and liquids. Vortex pumps can handle larger and heavier solids, and fibrous materials, heavy and gassy sludges are pumped with ease. We offer a wide range of Vortex pumps, suitable for both submerged (DWP and DNP series) and dry installation (BWP and BNP series), and in various materials such as cast iron, Nihard 4 or Duplex.
Advantages:
- best non-clogging performance
- most reliable principle
- low impeller wear
- minimal vibrations
- constant performance
- cleaner sumps due to the created Vortex
Our pump series BWP-42 are also available with sledge construction.
