Chopper pumps for biogas plants
The model DG-I submersible chopper pump is particularly suitable for biogas plants. This heavy-duty chopper pump is designed with an open impeller, which is the ideal design for pumping feedstocks with high dry matter content and high viscosity.
The pump’s unique chopping system, or knife system, proves extremely effective in situations, where large particles and contaminants often create problems for other types of pump.

Looking for a tough, reliable pump? This is it.
The benefits of chopper pumps for biogas
- The pump both pumps and chops in one function, which counteracts clogging or blocking. At the same time, it is advantageous for the entire biogas process, which as a result of, reduced particle size gets a biomass that is easier to “eat” for the bacteria in the reactor.
- Small foreign objects such as gravel, sand, small shards of glass, bone, etc., can pass through the pump without causing damage and with minimal wear.
- The operating range of the pumps is up to 6 bar, which is why they can also replace most types of displacement pumps.
- The pump has a simple and robust construction and is easy to service.
- For liquids with abrasive particles such as sand, Landia has developed special materials so that the service life of the pump is significantly extended compared to a standard pump.
- The pump can be supplied in stainless steel for operation in aggressive liquids.
