Powerful, Efficient Double Suction Pumping for Critical HVAC Applications
The Series e-HSC double suction pump is designed to provide engineers, contractors, and building owners with a high-performance solution for demanding HVAC systems. Built by a leader in hydronic pump technology, the e-HSC offers the strength, efficiency, and serviceability needed for chillers, boilers, cooling towers, and hydronic distribution systems.
Every building depends on reliable HVAC performance to support comfort, productivity, and indoor environmental control. The Series e-HSC helps meet those demands with rugged engineering, high-capacity operation, and optimized hydraulic performance for a wide range of commercial and institutional applications.
With flow capabilities up to 26,600 GPM, the e-HSC is built to handle large-capacity systems and higher head requirements. Its shorter shaft design helps reduce vibration and extend bearing life, allowing the pump to run up to three times longer within the preferred operating range before bearing replacement is needed.
The e-HSC is also designed for easier service. Mechanical seals and bearings can be accessed without opening the upper casing, helping reduce maintenance time and system downtime. A standard spacer coupling makes seal and bearing replacement more convenient, while the seal chamber and mechanical seal design work with incoming pressure without requiring an external flushing solution.
Each model is optimized to balance efficiency and suction head requirements. With a complete range of pump selections available, the e-HSC makes it easier to match the right pump to each flow requirement while staying close to the best efficiency point.
