To expertly balance axial thrust, our design incorporates advanced wear rings strategically positioned at both the front and back of the majority of the impeller. Additionally, a sophisticated balance hole is integrated into the back shroud of the impeller. For certain pumps where axial thrust remains minimal, the design is elegantly simplified without a rear wear ring and balance hole.
Our high-precision casting impeller is meticulously crafted to ensure impeccable performance. Available in a selection of materials such as cast iron, stainless steel, and bronze, these materials offer robust durability and superior efficiency.
The pump cover is thoughtfully designed with a soft packing seal, equipped with stuffing that can channel pressurized water for effective seal cooling, lubrication, and cleaning, ensuring optimal performance and longevity.
Our mechanical seal options include both single and double mechanical seals, providing versatile solutions for varied needs. A precision-engineered seal cavity allows a controlled flow of pressurized water, efficiently cooling and rinsing the end surface friction points. For specialized applications, our seals can be configured to ISO3069 standards, featuring designs like corrugated pipe and expeller seals to meet specific requirements.
Flexible Couplings
Flexible couplings redefine durability by accommodating movement such as vibrations and thermal expansion without incurring damage. Ideal for situations with inevitable misalignment between drive and pump shafts, they excel in absorbing vibrations, thereby reducing operational noise. Despite the initial complexity and cost, these couplings offer significant maintenance savings by protecting shafts and bearings from damage and premature wear, ensuring a long-term return on investment.
We incorporate wear-resisting disc couplings or pin couplings, delivering enhanced durability and reliability in demanding environments.
