To meticulously balance axial thrust, our design includes precision-engineered wear rings positioned at both the front and back of the majority of the impeller. Additionally, a balance hole is strategically crafted on the back shroud of the impeller, ensuring seamless operation. For pumps where the axial thrust is minimal, the design elegantly omits the need for a wear ring and balance hole at the impeller's rear, optimizing the efficiency and performance.
Our high-precision casting impeller assures exceptional performance and reliability, available in robust materials such as cast iron, stainless steel, and bronze. This ensures that the impeller not only meets but exceeds industry standards, providing long-lasting and durable service.
The pump cover is thoughtfully equipped with a packing system utilizing soft packing seals. The inclusion of this advanced system allows water under a controlled pressure to pass through for effective seal cooling, lubrication, and cleaning. This ensures optimal performance and prolongs the life of the product.
Our sophisticated sealing systems feature both single and double mechanical seal options. By introducing water at a specific pressure into the seal cavity, the end surface friction is efficiently rinsed, enhancing the cooling effect. The flexibility to adapt to a predetermined ISO3069 size and structure, including options like a mechanical seal with a corrugated pipe and expeller seal, ensures our product meets diverse application needs.
Flexible Couplings
Unlike their rigid counterparts, our flexible couplings are designed to accommodate slight movements such as vibrations and thermal expansion without sustaining damage. This feature makes them perfect for scenarios with unavoidable misalignments between drive and pump shafts. Their ability to absorb vibrations effectively also contributes to significantly reducing excessive operational noise. While they are more complex and costly to design, their ability to safeguard shafts and bearings from wear and premature failure results in considerable maintenance savings over time.
Our solutions incorporate the use of wear-resistant disc couplings or pin couplings, ensuring durability and efficient performance in demanding environments.
