According to KSB, the series has been developed to meet the increasing demand for high-performance circulating pumps for HVAC systems.
The new Etaline-R type series has a compact in-line design and requires less space than conventional long-coupled models.
The pump series generates a maximum flow rate of 1,900 m3/hr and a maximum discharge head of 97 m. The nodular cast iron casing and the mechanical seal are designed for operating pressures of up to 25 bar each. The mechanical seal employed is available in a large number of materials and the pump can cope with a maximum operating temperature of 140 °C.
Each Etaline-R type pump is delivered with an impeller whose diameter has been matched to its operating point, ensuring that the pumps achieve the best efficiency point and will not be oversized. Each pump set features an IE2 electric motor whose high efficiency contributes to the new type series cost-effectiveness.
The series comprises 14 pump sizes and its maximum motor rating is 315 kW. Up to a motor rating of 45 kW, motor-mounted speed control systems type PumpDrive can be supplied optionally. For higher ratings, the speed control system is traditionally integrated in a control cabinet.
