The Ebara Ego range comprises wet rotor electronic circulators with permanent magnet ECM motors and integrated electronic control, designed for the circulation of hot and cold water in domestic centralised heating, air conditioning, and solar systems. Because the rotor is lubricated directly by the pumped liquid, there is no mechanical seal, eliminating a common maintenance point.
The Ego T is a compact cast iron circulator with threaded connections and Noryl impeller, suited to small domestic systems, with a liquid temperature range of +5°C to +95°C, flow rates from 0.8 to 4m³/h, and maximum pressure of 10 bar. The Ego 2 Easy is a larger cast iron model available in threaded or flanged versions, covering flow rates from 2.0 to 9.5m³/h and liquid temperatures from +2°C to +110°C, suitable for medium-sized centralised and collective systems. Both use ECM technology to automatically adjust pump performance to actual system demand.
All Ego models automatically regulate differential pressure based on the system’s real-time demand, reducing energy consumption and noise compared to fixed-speed alternatives. The Ego 2 achieves an EEI of less than 0.12, placing it among the best in its category, and all models comply with the ErP Directive. Maximum glycol concentration is 20%.

The Ego range is a family of wet rotor electronic circulators with ECM permanent magnet motors and integrated electronic control, designed for heating, cooling, and solar circulation in domestic and commercial buildings.
Ego models use wet rotor construction, the rotor and bearings are immersed in and lubricated by the pumped liquid, eliminating the need for a mechanical seal and removing a common maintenance requirement.
Ego circulators are compatible with single-pipe, two-pipe, and underfloor heating systems, as well as mixing loops in larger installations and constant or variable flow solar thermal systems.
The maximum water/glycol mixture is 20% for all Ego models. Higher concentrations increase viscosity and should be checked against the circulator’s performance data before use.
