Between-the-bearings: Experience the robust design of our split-case pumps, recognized as "between-the-bearings" pumps. This sophisticated engineering marvel features an impeller that is strategically mounted on a shaft, expertly supported by bearings on either side for enhanced stability and performance.
Double-suction impeller: Discover the distinct advantage of split-case pumps, celebrated for their unique double-suction impeller design. This innovative feature significantly reduces the load on the bearings, unlike single-suction impellers that draw water from only one side, thereby promoting longevity and efficiency in operation.
Our high-precision casting impeller guarantees optimal performance and reliability, available in a variety of materials including cast iron, stainless steel, and bronze, each chosen for their durability and superior quality.
Packing seals have remained the quintessential sealing solution for decades, employing rope-like materials to envelop the pump shaft, expertly filling dead spaces to minimize fluid loss. However, as the gland packing material naturally wears over time, fluid loss may increase, potentially affecting lubrication or ease of replacement necessary for optimal functionality.
Mechanical seals are the premium choice over traditional packing seals for applications where leakage mitigation is critical. These seals offer superior durability and are engineered to endure substantial operational demands. Their design includes multiple sealing points, effectively minimizing any potential leakage concerns.
Flexible couplings
Flexible couplings stand out with their ability to accommodate movement such as vibrations and thermal expansion without sustaining damage, unlike their rigid counterparts. Ideal for situations with unavoidable misalignment between the drive and pump shafts, they also excel in reducing excessive noise thanks to their vibration-absorbing properties. Despite their more complex and costly design, they offer significant long-term maintenance savings by safeguarding shafts and bearings against damage and premature wear.
Our selection includes wear-resisting disc couplings or pin couplings, each designed to enhance durability and performance.
This exceptional product finds broad applications across a diverse array of sectors. It is extensively employed in urban water supply and drainage systems, ensuring seamless water distribution and removal.
