Design Features:
* With symmetrically arranged impeller rotor components, axial forces generated by all levels of symmetrical impellers forces offset each other and automatic balancing of huge axial thrust within pump cavity can be realized without the balance disc structure.
* Unique throtting and pressure reduction devices, odd-level balancing device.
* By canceling easy-failing balancing disc, pump reliability is greatly improved, maintenance frequency and maintenance cost are reduced.
* No mechanical balancing drum, disc or similar device, which ensure pump could be applied into more wider range of application.
Precision cast impellers
* smooth surface finish for improved hydraulic efficiency.
* multiple hydraulic designs for best customer fit.
* optional wear rings available to restore “as built” clearances.
* variety of materials available for different services.
Continuous channel mulitvane diffuser and stage piece
* eliminates one mating interface.
* provides additional rigidity for more reliable operation.
* simplifies maintenance procedures and reduces inventory requirements.
* smoothly directs the flow from stage to stage more efficiently.
* eliminates radial loads to assure longer bearing life.
Wear rings
* allow restoration of “as built” clearances.
* protect more expensive parts from wear.
* casing rings are standard.
* impeller rings are an option.
