B Pump

Main applications

  • Cooling water and condensate
  • Energy
  • Groundwaterlevel (mining/buildings)
  • Power Stations < 100 MW
  • Power Stations > 100 MW
  • Water
  • Water Extraction

Technical data

Q max 2,600.0 m³/h
H max 160.0 m


Main pump parts are the Pump Bowl Assembly, Column Pipe Assembly, and Discharge head assembly. Bowl assembly consists of single or multistage radially split, interchangeable intermediate bowls. Column Pipe Assembly consists of interchangeable lengths of the column pipes and variable setting depth. Discharge head assembly consists of discharge head with packed stuffing zone/mechanical seal and thrust bearing arrangement (in case of solid shaft drive only).


These pumps are suitable for water supply schemes, irrigation schemes, lowering of ground water and dewatering of mines and construction sites. Deep well turbines are particularly suitable for narrow bore holes. Minimum borehole sizes range from 200mm to 675mm.
