To ensure optimal balance of axial thrust, this innovative pump system is designed with wear rings located at the front and back of most impellers, complemented by a balance hole on the rear shroud of the impeller. For some pumps where the axial thrust is minimal, the design is simplified by omitting the rear wear ring and balance hole, maintaining efficiency and precision.
Our high-precision casting impeller is crafted to guarantee unparalleled performance. Available in robust materials such as cast iron, stainless steel, and bronze, it exemplifies durability and superior craftsmanship.
The sophisticated packing pump cover is ingeniously equipped with stuffing for a soft packing seal. This design allows for the introduction of pressurized water, serving to cool, lubricate, and cleanse the seal effectively, enhancing overall pump longevity and reliability.
Our system offers two meticulous types of mechanical seals: single and double. Water is introduced under pressure into the seal cavity, facilitating end surface friction rinsing, while providing a cooling effect. Depending on specific requirements, the sealed cavity can be adapted into pre-defined ISO3069 structures, accommodating advanced solutions like mechanical seals with corrugated pipes and expeller seals.
Flexible couplings
In contrast to rigid couplings, our flexible couplings are engineered to handle minor movements such as vibrations and thermal expansion without incurring damage. They are ideal for scenarios with inevitable misalignment between drive and pump shafts. Known for their exceptional ability to absorb vibrations, flexible couplings also contribute to noise reduction during operations. Although their design is more intricate and costly, the longevity and protection they offer to shafts and bearings translate into significant maintenance savings over time.
We strategically employ wear-resisting disc couplings or pin couplings to ensure enduring performance and reliability for various applications.
