Impeller type pump rph
▪ Closed radial impeller
▪ Impeller with impeller wear ring on the suction side (if required also on the discharge side)
▪ Sealing gap and balancing holes balance axial forces.
Optional:
▪ Inducer to improve the NPSH value
As standard IP-55 IEC electric motor. For non monobloc pumps, IM 1001 (IM B3) construction. For monobloc pumps, as standard, IM 3001 (IM B5) construction.
