Between-the-Bearings: Experience the superior engineering of our split-case pumps, renowned as 'between-the-bearings' systems. This innovative design strategically positions the impeller on a shaft that is meticulously supported by bearings on both sides, ensuring optimal balance and enhanced durability.
Double-Suction Impeller: Our split-case pumps boast a distinct advantage as the premier pump type featuring a double-suction impeller. This advanced configuration significantly reduces the load on bearings, a common challenge in single-suction models, thereby boosting performance and longevity.
High-Precision Casting: Our impellers are crafted with precision casting techniques to guarantee superior performance. Available in robust materials such as cast iron, stainless steel, and bronze, these impellers promise durability and reliability in demanding environments.
Packing Seals: Historically the go-to sealing solution, packing seals employ rope-like materials to wrap around the pump shaft, effectively minimizing fluid loss. However, over time, these seals may wear, leading to increased fluid loss and potential issues with lubrication and ease of replacement.
Mechanical Seals: For critical applications where leakage is a concern, mechanical seals are a modern, superior choice. These seals offer enhanced durability and are engineered to withstand demanding conditions. Employing multiple sealing points, they virtually eliminate leakage, ensuring reliable performance.
Flexible Couplings
Flexible Couplings: Unlike their rigid counterparts, flexible couplings excel in accommodating movements such as vibrations and thermal expansion, preventing damage. Ideal for setups with slight misalignment, they reduce noise and offer maintenance savings despite their complex design and higher cost.
Advanced Coupling Options: We employ wear-resisting disc or pin couplings, known for their durability and ability to enhance the longevity of your pump systems.
