To expertly manage axial thrust, our advanced design incorporates wear rings both at the front and back of most of the impeller, complemented by a strategically placed balance hole on the back shroud. For some pumps where the axial thrust is minimal, there is no need for a rear wear ring and balance hole, showcasing our efficiency-driven engineering.
The high-precision casting of the impeller guarantees unmatched performance and quality. Available in robust materials like cast iron, stainless steel, and bronze, these impellers are designed to withstand demanding environments, ensuring longevity and reliability.
Our packing pump cover, equipped with soft sealing stuffing, serves to provide essential cooling, lubrication, and cleaning. By allowing a certain pressure of water to pass through, it ensures the seal performs optimally, enhancing the durability and effectiveness of the pump operation.
We offer both single and double mechanical seals for versatile applications, with a specialized approach of introducing water into the seal cavity at a specified pressure. This process rinses the end surface friction while providing crucial cooling. Tailored to meet ISO3069 standards, our seals can be adapted for customized cavity structures, including options like mechanical seals with corrugated pipes and expeller seals, ensuring superior performance across diverse needs.
Flexible couplings
Flexible couplings, unlike their rigid counterparts, are crafted to accommodate movements such as vibrations and thermal expansions without incurring damage. They are ideal for scenarios with unavoidable misalignment between drive and pump shafts. Additionally, their ability to absorb vibrations helps in significantly reducing operational noise. While these come with a complex and relatively costlier design, their protective nature safeguards the shaft and bearings, thus offering substantial maintenance savings over time.
Our choice of wear-resisting disc coupling or pin coupling demonstrates our commitment to durability and performance.
