Circulation pump ESN50-12-280 (1000W)

Circulation pump EPA ESN50-12-280 (1000 W)

This is a circulation pump designed to keep water moving continuously in heating and hot water systems. Its 1000 W motor delivers a flow of 20 m³/h and a head of up to 12 m, maintaining steady circulation in large-volume circuits. The TF110 temperature class allows safe operation with hot water up to 110 °C and installation directly in boiler room circuits. Maximum output power is 650 W, so the pump distributes power efficiently according to load.

Advantages

• 1000 W motor — provides continuous, stable circulation in large-volume systems
• High flow rate of 20 m³/h — circulates systems with multiple circuits and long pipe runs
• Head of up to 12 m — delivers heat to the upper points of multi-storey buildings
• Cast iron wetted section and aluminium motor housing — withstand pressure and draw heat away from the motor quickly
• Winding of solid copper wire — improves pump reliability and keeps it running continuously for years
• TF110 temperature class — safe operation with hot water up to 110 °C
• IP44 protection rating — protected against splashing water, reliable in damp rooms
• 650 W maximum output power — distributes power according to load and prevents unnecessary consumption

Application

Used in radiator heating systems to keep rooms warm and in underfloor heating circuits, where hot water circulating beneath the floor holds the room temperature even. It works alongside a boiler, sending water to the radiators and returning it; it is widely used in the heating systems of multi-storey residential buildings, offices and production facilities.

Note on use

Until the air has cleared from the system the pump runs with some noise. Once the air is fully out, it continues running quietly and steadily.
