Between-the-bearings: Split-case pumps are ingeniously designed as 'between-the-bearings' pumps, expertly mounting the impeller on a shaft that enjoys robust support from bearings on both sides. This strategic configuration ensures optimal stability and efficiency in operation.
Double-suction impeller: Uniquely among common pump designs, split-case pumps boast a double-suction impeller. This innovative feature imposes significantly fewer loads on the bearings, unlike a traditional single-suction impeller that draws water from only one side, thereby enhancing durability and performance.
High-precision casting impeller: Crafted with exceptional precision, this impeller guarantees unparalleled performance. Available in cast iron, stainless steel, and bronze, it offers versatility and reliability across diverse applications.
Packing seals: Renowned for their widespread usage, packing seals employ rope-like materials intricately wrapping around the pump shaft. They effectively minimize fluid loss by filling dead spaces, though they may eventually wear, impairing lubrication and ease of replacement. This classic approach demands regular maintenance to maintain optimal function.
Mechanical seals: Favoured for their superior durability and efficiency, mechanical seals are expertly designed to address leakage concerns in various applications. By utilizing multiple sealing points, they are able to virtually eliminate leakage, making them a reliable choice over traditional packing seals.
Flexible couplings
Flexible couplings: These ingeniously designed couplings excellently accommodate movement, such as vibrations and thermal expansion, without incurring damage. Ideal for scenarios with unavoidable misalignment, they absorb vibrations and significantly reduce operating noise. While more complex and costly, they protect shafts and bearings from damage and wear, ultimately offering long-term maintenance savings.
Wear-resisting couplings: We employ durable disc couplings or pin couplings to ensure long-lasting performance and resistance to wear, supporting the overall efficiency and longevity of our pumping systems.
