Structural characteristics

This series of products is a multi-stage pump with a well type outer cylinder, and the liquid suction method is very suitable for use as a condensate pump or drain pump with high suction performance requirements in nuclear/thermal power units. The first stage impeller has two forms: single suction and double suction. The double suction structure is generally used for products with a suction diameter of 350mm or more.

The pump adopts water lubricated bearings, shaft seals as packing or mechanical seals.

The axial force of the rotor of LNT series products is borne by the motor thrust bearing. LNTP products are designed with balancing devices and thrust bearings to withstand their own axial forces.
