To expertly balance axial thrust, our pumps feature wear rings strategically positioned both at the front and rear of most impellers. Complementing this is a meticulously designed balance hole on the back shroud of each impeller. For pumps where the axial thrust is minimal, we've innovatively designed them without the need for a rear wear ring or balance hole, ensuring efficiency without compromising performance.
Our high-precision casting impellers are crafted to guarantee superior performance and durability. Available in robust materials such as cast iron, stainless steel, and bronze, each impeller is designed to meet the highest standards of reliability and longevity.
The packing pump cover is ingeniously equipped with stuffing, tailored for a soft packing seal. It allows for the infusion of water under specific pressure, serving multiple purposes: cooling the seal, providing lubrication, and facilitating cleaning. This thoughtful design ensures optimal performance and longevity.
We offer both single and double mechanical seals, each engineered to accommodate various requirements. Water is introduced into the seal cavity at a precise pressure to cleanse the end surface friction and enhance cooling. Depending on the application, the cavity can be adapted to a predetermined size per ISO3069 standards, incorporating advanced structures like corrugated pipes and expeller seals for enhanced effectiveness.
Flexible couplings
In contrast to rigid couplings, flexible couplings are artfully designed to handle movement, such as vibrations and thermal expansion, without sustaining damage. This makes them the perfect choice for applications prone to unavoidable misalignment between drive and pump shafts. Their ability to absorb vibrations effectively also helps in significantly reducing operating noise. Despite their complex and costlier design, the long-term advantages are substantial as flexible couplings protect the shaft and bearings, ultimately leading to significant maintenance savings.
Our commitment to durability is showcased in our use of wear-resistant disc couplings or pin couplings, designed to offer longevity and resilience.
