To expertly balance axial thrust, our design incorporates precision-engineered wear rings at both the front and back of the majority of impellers, complemented by a strategically positioned balance hole on the impeller's back shroud. For pumps where axial thrust is minimal, we efficiently omit the back wear ring and balance hole, optimizing performance without compromise.
Our high-precision casting impeller guarantees unmatched performance and durability, crafted in a selection of premium materials including cast iron, stainless steel, and superior bronze.
The packing pump cover is ingeniously fitted with soft packing seals, allowing for the strategic passage of pressurized water. This innovation ensures optimal seal cooling, lubrication, and cleaning, enhancing the pump's longevity and reliability.
Our advanced sealing solutions offer versatility with both single and double mechanical seal options. These are designed to introduce water at a precise pressure into the seal cavity, effectively rinsing end surface friction and providing a cooling effect. Additionally, the design is adaptable to ISO3069 standards, accommodating other configurations such as mechanical seals with corrugated pipes and expeller seals, catering to diverse application requirements.
Flexible Couplings
In contrast to their rigid counterparts, flexible couplings proficiently handle movement such as vibrations and thermal expansion without sustaining damage, making them exemplary for applications involving inevitable misalignment between drive and pump shafts. Their ability to dampen vibrations results in reduced operational noise levels. While this sophisticated design entails a higher initial cost, the long-term advantages of safeguarding shafts and bearings against damage and premature wear culminate in notable maintenance savings.
We incorporate robust wear-resisting disc coupling or pin coupling for enhanced durability and performance.
