Product Range

Acid-Proof Stainless Steel Chopper Pumps

Acid-Proof Stainless Steel Chopper Pumps

Ideally suited to chop, mix and pump coarse solid particles, these new acid-proof chopper pumps can be utilised in very harsh environments without the worry of corrosion, subsequent failure and costly replacement.

Furthermore, Landia's innovative knife system eliminates downtime because unlike conventional products, the chopper pump does not clog up or have to be regularly removed from use for cleaning or inspection.

Available as a submersible pump, dry-installed pump or as a long shaft pump for wet-well installations, Landia's chopper pump is also suitable for processing sludge in a wide range of industrial effluents.


BioChop Fish Silage Tank

BioChop Fish Silage Tank

Landia’s new free-standing BioChop Fish Silage Tank processes by-products such as bones and intestines (even rejected whole fish) into a thin product that can be pumped to a tanker for future use, such as a biogas plant.

Developed specifically to meet the requirements of the fish processing industry, the Biochop is designed with rugged shredder propeller and a specially designed knife system to deal with all kinds of fish remnants.  The system also has the option of automatic acid dosing for when liquid needs to be stored for extended periods.

The resulting residual product from Landia’s Biochop can also be refined for use or sale as valuable raw materials such as animal feed, as well as an energy-efficient substrate for AD plants.

In addition to significant cost savings on labour, transport and disposal, Landia’s Biochop minimises foul odours and prevents pests from entering residual products.

BioMover Mixer

BioMover Mixer

Landia’s BioMover mixer ensures full contact between bacteria and nutrients, without damaging the biofilm carriers in MBBR and IFAS processes.

Designed specifically for biofilm carrier mixing, in which Landia has over 15 years worldwide experience, BioMover produces propeller tip speeds from only four to eight m/sec to ensure very gentle treatment of biofilm carriers and sludge.

BioMover’s stainless steel propeller with its wide blades and low tip speed provides guaranteed gentle and energy efficient mixing to keep solids in suspension and prevent biomass from settling on the tank floor - as well as keeping sieves free from clogging.

Compatible with all types of biofilm carriers, Landia’s low life-cycle cost BioMover is extremely durable, available in cast iron with a two-component epoxy coating, or in stainless steel.

Floating Airjet

Floating Airjet

Designed to be suspended on pontoons, making it ideal for lagoons when adjusting to liquid levels, The Floating Air Jet has been added to Landia’s proven range of aeration and mixing systems.

Also available as an externally-mounted system for above-ground tanks, or as a free-standing or guide-rail mounted Submersible, Landia’s Air Jet uniquely combines a highly efficient air ejector with chopper pumps for optimum oxygen transfer rates.

Easy to install, even in flooded tanks, and suitable for operation where liquid levels vary, the self-aspirating Air Jet provides a completely non-clogging aeration system.

Capable of handling sewage, stormwater, industrial effluent and agricultural waste, this highly effective aerator boasts vigorous mixing capabilities, which as well as improving oxygen transfer, prevent sedimentation.

Submersible mixers

Submersible mixers

The submersible Landia mixers are available in so many different designs that it is always possible to find the optimal combination of the required raw strength, process requirements and the shortest possible operating time to minimise energy consumption, wear and noise level.
