The Stanley Fisher Eltra Series is a high-efficiency ECM wet rotor circulator pump engineered for residential and light commercial hydronic heating, domestic hot water recirculation, and small HVAC systems. Electronically controlled operation delivers intelligent performance while reducing energy consumption.
Built on permanent magnet motor technology, Eltra circulators automatically adapt to system demand through proportional pressure, constant pressure, and fixed speed operating modes. Integrated protection features support reliable startup, quiet operation, and long-term service life.
Eltra pumps feature threaded connections, PN10 pressure rating, and compact installation dimensions for easy retrofit or new system integration in closed loop heating and circulation applications.
The Eltra Series features a high-efficiency wet rotor design integrating the hydraulic assembly and ECM permanent magnet motor into a single, compact unit. This construction supports quiet operation, reduced energy consumption, and long service life in residential and light commercial hydronic systems.
Electronically controlled operating modes include proportional pressure, constant pressure, and fixed speed settings, allowing the pump to adapt to varying system demands while optimizing hydraulic performance and electrical efficiency. Integrated dry-run protection, automatic summer mode, and soft-start functionality enhance operational reliability.
Eltra circulators are supplied with threaded connections in 130 mm and 180 mm installation lengths and are rated for PN10 service. Durable materials and precision-balanced components support continuous duty operation in closed-loop heating, domestic hot water recirculation, and small HVAC applications.
