Dry Installed Vortex Pumps – BWP and BNP series

Our Landustrie dry installed flooded suction vortex pumps are designed to offer the best efficiency and non-clogging performance for pumping waste water containing solids in industries such as sewage, recycling and food processing (for example pumping away chicken feathers) and are also used in clear water applications such as sprinkler systems.

The recessed vortex impeller leaves a wide unobstructed passage through the volute case in which a strong vortex is created, passing most of the solids in front of the impeller without touching it.

The wet parts of the pumps are available in cast iron (BWP), hard iron (BNP) for increased resistance to abrasion or Duplex stainless steel (BWP-U) for increased resistance to chemical corrosion.

BWP22/42/62/82
BNP22/42/62
BWP22/42/62-U
Configuration options include horizontal, vertical, long coupled, short coupled, belt driven and bare shaft. An optional seal flush connection is available to enable seal flushing as part of the maintenance schedule.
BWP and BNP series
The BWP42 series pumps are also available with the option of rails on the base plate to slide the motor and seal housing section back from the pump housing for ease of access to the impeller and shaft seal during maintenance.
The different models are shown in the table below, along with the old Robot pump numbers. Please click on the model numbers for data sheets.
