NOMINAL OPERATION PARAMETERS AT PURE WATER PUMPING
(for the maximum rotation speed and the largest rotor)

*Pump construction enables decreasing the operational parameters by reducing the rotation speed and/or reducing the rotor’s diameter, adapting the pump to the system without choking the pump.

TYPICAL APPLICATIONS

  • pumping mixtures of water and solids, with large grains and higly abrasive properties,
  • pumping mixtures od water and quartz sand, ores, coal, slag, ash,
  • mining – WPJ pumps intended to replace hydrotransport drainage pumps used so far,
  • water supply systems,
  • pressure boosting,
  • technological processes,
  • industrial systems,
  • filtration systems.

KEY ADVANTAGES

  • long life ensured by the use of state-of-the-art corrosion and erosion resistant materials,
  • possibility of operation with a frequency converter,
  • possibility of serial operation,
  • the pumped mixture density can reach ρmax = 1700kg/m3 while pumping mixtures with a 50% content of solids in water,
  • silent and smooth operation,
  • connection dimensions in compliance with hydrotransport pumps,
  • inflow and suction operation,
  • approved for operation in explosion-hazard zones – ATEX Ex I M2.

PUMP PERFORMANCE CURVE

  • H = f(Q) – lift head acc. to rate flow,
  • P = f(Q) – power input acc. to rate flow,
  • η = f(Q) – efficiency acc. to rate of flow,
  • dz – impeller diameter,
  • n – rotational speed.

MAIN DIMENSIONS OF PUMP

CONNECTION SIZES OF PUMP

The flanges are normally made in accordance with the standard PN-EN 1092-1 or PN-EN 1092-2.

MAIN DIMENSIONS OF PUMP UNIT

It is possible to produce pumps with parameters different than those presented in the tables and on the graphs per agreement with the manufacturer.
