To expertly balance axial thrust, our design features wear rings both at the front and rear of most impellers. Additionally, a sophisticated balance hole is positioned on the back shroud of the impeller. However, for those pumps where axial thrust is minimal, the design efficiently omits the rear wear ring and balance hole, maintaining peak performance without unnecessary components.
Our high-precision casting impeller is meticulously engineered to uphold unrivaled performance. Available in premium materials such as cast iron, stainless steel, and bronze, each impeller promises reliability and longevity, epitomizing quality craftsmanship.
The pump cover integrates an advanced packing system equipped with soft packing seals. This innovative design allows the stuffing to circulate pressurized water, ensuring optimal seal cooling, lubrication, and cleanliness, thus enhancing operational efficiency and longevity.
Our mechanical seal options include both single and double mechanical seals. Ingeniously designed, they incorporate a specific pressure of water into the seal cavity for effective end surface rinsing and cooling. We also accommodate ISO3069 structures, offering alternatives like mechanical seals with corrugated pipes and expeller seals to meet diverse needs and preferences.
Flexible Couplings
Flexible couplings are engineered to adapt seamlessly to movements such as vibrations and thermal expansion, preventing potential damage. Ideal for scenarios with unavoidable shaft misalignment, they excel at absorbing vibrations, thereby reducing operational noise. While featuring a more intricate design compared to rigid couplings, the long-term benefits include safeguarding shafts and bearings from damage and premature wear, resulting in significant maintenance savings.
For optimal performance, we utilize wear-resistant disc couplings or pin couplings, ensuring durability and efficient power transmission.
