In order to meticulously balance axial thrust, our system boasts wear rings strategically positioned both at the front and back of the majority of the impeller. Additionally, a balance hole is ingeniously incorporated on the back shroud of the impeller. For some pump designs where the axial thrust is comparatively smaller, the absence of a wear ring and balance hole at the rear of the impeller is observed.
Our high-precision casting impeller is meticulously crafted to ensure superior performance. It is available in various high-quality materials, such as cast iron, stainless steel, and bronze, tailored to meet diverse operational demands.
The packing pump cover is ingeniously equipped with stuffing to facilitate a soft packing seal. The stuffing ingeniously allows the passage of water under a certain pressure for efficient seal cooling, lubrication, and cleaning, delivering enhanced performance and reliability.
Our mechanical seal options include both single and double mechanical seals, catering to diverse sealing requirements. By channeling water under a certain pressure into the seal cavity, the end surface friction is efficiently rinsed while achieving a superior cooling effect. Adaptations to ISO3069 allow for customization, such as incorporating structures like a mechanical seal with a corrugated pipe and an expeller seal, tailored to specific needs.
Flexible Couplings
Unlike rigid couplings, our flexible couplings are engineered to accommodate a degree of movement, such as vibrations and thermal expansions, without sustaining damage. This adaptability makes them perfect for applications where slight misalignment between the drive and pump shafts is inevitable. Their superior vibration absorption capability also helps minimize excessive operating noise. Although they feature a more complex and costly design, the significant reduction in shaft and bearing damage and premature wear translates to substantial maintenance savings over time.
We employ either wear-resisting disc coupling or pin coupling, each designed to deliver optimal performance and durability.
This exceptional product finds extensive application in a plethora of sectors, making it an indispensable solution for various water-related needs. Whether it's the efficient urban water supply and drainage, or the robust infrastructure of central heating systems, this pump system excels. Ideal for industries such as iron and steel metallurgy, oil refineries, and paper mills, it ensures seamless operations. Moreover, it serves the demanding needs of power plants, airports, chemical plants, and textile mills with unparalleled performance. From sugar mills to plant mines, consumer drainage systems, and air conditioning systems, this versatile pump system delivers outstanding results.
