Our innovative design ingeniously balances axial thrust by equipping most of our impellers with wear rings both at the front and back, along with a strategically positioned balance hole on the back shroud of the impeller. For those pumps where the axial thrust remains minimal, the design is streamlined without the need for a back wear ring and balance hole, ensuring efficient performance without unnecessary components.
Crafted with high-precision casting technology, our impellers guarantee exceptional performance. Available in a robust selection of materials including cast iron, stainless steel, and bronze, these impellers are engineered for durability and reliability.
Our packing pump covers are thoughtfully designed with stuffing to accommodate a soft packing seal. This setup allows for the infusion of water at a controlled pressure, facilitating seal cooling, lubrication, and cleaning, thus enhancing the longevity and efficiency of the pump.
We offer two diverse types of mechanical seals: single and double. Both are designed to introduce water into the seal cavity under specific pressure, effectively rinsing the end surface, minimizing friction, and ensuring optimal cooling. To meet varying needs, our design accommodates ISO3069 structured sealed cavities, available with advanced features like corrugated pipe mechanical seals and expeller seals.
Flexible Couplings
Flexible couplings are engineered to accommodate movement such as vibrations and thermal expansion, preventing damage. Ideal for scenarios with misalignment between drive and pump shafts, they absorb vibrations to reduce operating noise. While their design is more sophisticated and costly compared to rigid couplings, they offer long-term savings by protecting shafts and bearings from damage and premature wear.
We incorporate either wear-resisting disc couplings or pin couplings, ensuring high durability and performance.
