This series of multistage centrifugal pumps, with a well type tube, are inhaled under liquid, and are suitable to be used as condensate pumps or hydrophobic pumps for nuclear power / thermal power units with high suction performance. The impeller has a single head with high head and less series, which effectively reduces the pump length.
Water lubricated bearings and shaft seals are used as packing or mechanical seals.
The rotor axial force of the JNT series is borne by the thrust bearing of the motor. The JNTP product is designed as a balancing device and a thrust bearing to bear its own axial force.
