Expertly engineered to balance the axial thrust, our pumps are designed with wear rings both at the front and rear of the majority of the impeller. Additionally, a balance hole is strategically placed on the back shroud of the impeller. In cases where the axial thrust is minimal, our innovative design allows for the omission of the wear ring and balance hole at the back of the impeller, ensuring efficient performance tailored to specific needs.
Our high-precision casting impeller guarantees remarkable performance, available in robust materials like cast iron, stainless steel, and bronze. This meticulous craftsmanship ensures reliability and efficiency in every application.
The thoughtfully designed packing pump cover is equipped with stuffing tailored for a soft packing seal. This system allows the stuffing to pass a controlled pressure of water, providing essential seal cooling, lubrication, and cleaning, ensuring maximum operational efficiency and longevity.
Our product offers two advanced types of mechanical seals: single and double. These seals enable water to enter the seal cavity at a predetermined pressure, effectively rinsing the end surface friction while offering a cooling effect. According to specific demands, our seals can adapt to form sizes aligned with ISO3069, embracing structures such as mechanical seals with corrugated pipes and expeller seals.
Flexible Couplings
Flexible couplings revolutionize connectivity by accommodating movement, such as vibrations and thermal expansions, without inflicting damage. Perfect for applications with unavoidable misalignment between drive and pump shafts, they absorb vibrations to reduce excessive noise. While their sophisticated design may be more costly, they offer significant maintenance savings by protecting shafts and bearings, thus preventing premature wear and extending the lifespan of components.
Our systems incorporate wear-resistant disc couplings or pin couplings, ensuring durability and optimal performance across various applications.
