To achieve optimal balance of axial thrust, our design incorporates strategically placed wear rings both at the front and rear of the impeller, complemented by a finely crafted balance hole on the back shroud. However, when axial thrust is minimal, we eliminate the rear wear ring and balance hole, streamlining the design without compromising performance.
Our impellers are high-precision castings, meticulously engineered to ensure superior performance. Available in a variety of materials including robust cast iron, durable stainless steel, and versatile bronze, these impellers are tailored to meet diverse industrial needs.
The packing pump cover, ingeniously designed with stuffing, is utilized for a soft packing seal. It allows the passage of pressurized water, which is essential for seal cooling, lubrication, and cleaning, thereby enhancing the longevity and efficiency of the pump.
Our mechanical seal systems boast two sophisticated options: single and double mechanical seals. By introducing pressurized water into the seal cavity, we ensure the end surfaces remain cool and free from friction. For bespoke requirements, we can adapt the seal cavity to adhere to ISO3069 standards, integrating advanced structures like corrugated pipe seals and expeller seals.
High-Performance Flexible Couplings
Flexible couplings are the unsung heroes of pumping systems, adeptly accommodating movements like vibrations and thermal expansions, safeguarding against misalignment between drive and pump shafts. Their ability to absorb vibrations reduces noise levels significantly. Although they feature a more complex and costly design, the long-term benefits are undeniable. By protecting shafts and bearings from damage and excessive wear, flexible couplings offer substantial maintenance savings.
Our selection includes wear-resistant disc couplings and pin couplings, each designed to enhance durability and performance.
