To expertly balance axial thrust, the ingenious design incorporates both front and back wear rings on the majority of the impeller. Additionally, a balance hole is meticulously placed on the back shroud of the impeller. For certain pumps where the axial thrust is minimal, the sophisticated engineering allows for the exclusion of wear rings and balance holes at the back.
The high-precision casting impeller is a marvel of engineering, ensuring unparalleled performance. Available in robust materials such as cast iron, stainless steel, and bronze, it promises exceptional durability and efficiency.
The pump cover is a testament to meticulous engineering, equipped with stuffing for the soft packing seal. To ensure superior seal cooling, lubrication, and cleanliness, it facilitates the passage of water under specific pressure through the stuffing.
Our range includes single and double mechanical seals, ingeniously designed for optimum performance. Water under a precise pressure enters the seal cavity, effectively rinsing the end surface friction and providing a cooling effect. Tailored to meet ISO3069 standards, the sealed cavity can be adapted to other predetermined structures, including mechanical seals with corrugated pipes and expeller seals.
Flexible couplings
Flexible couplings are a triumph of design, seamlessly accommodating movement such as vibrations and thermal expansion, unlike rigid couplings. This makes them indispensable for applications with unavoidable misalignment between drive and pump shafts. Their proficiency in absorbing vibrations significantly reduces excessive operating noise. Despite their intricate, costly design, flexible couplings offer long-term benefits by safeguarding the shaft and bearings from damage and premature wear, thus ensuring maintenance savings.
We incorporate wear-resistant disc couplings or pin couplings, ensuring robust performance and longevity.
