To expertly balance axial thrust, most impellers are fitted with wear rings both at the front and rear, complemented by a strategically placed balance hole on the impeller's back shroud. In cases where the axial thrust is minimal, the impeller may not require a rear wear ring or balance hole.
Our high-precision casting impeller promises exceptional performance, available in premium materials such as cast iron, stainless steel, and bronze to meet diverse needs.
The packing pump cover is outfitted with stuffing for a soft packing seal. This stuffing can circulate water under pressure for optimal seal cooling, effective lubrication, and thorough cleaning.
We offer two distinctive types of mechanical seals: single and double mechanical seals. These seals allow water under pressure to enter the seal cavity, rinsing end surface friction while providing a cooling effect. Tailored solutions can utilize ISO3069 structures, including advanced designs such as mechanical seals with corrugated pipes and expeller seals.
Flexible Couplings
Flexible couplings, unlike their rigid counterparts, adeptly handle movement such as vibrations and thermal expansion without incurring damage. Ideal for scenarios with inevitable shaft misalignment, they excel at absorbing vibrations to minimize excessive noise during operation. While their design is more intricate and costly, flexible couplings provide long-term maintenance savings by shielding the shaft and bearings from damage and premature wear.
We incorporate durable, wear-resisting disc couplings or pin couplings for enhanced performance.
