Circulation pump ESN32-18-1.1 (1100W)

Circulation pump EPA ESN32-18-1.1 (1100 W)

This pump is designed to keep liquid moving continuously at industrial sites and in heating and water circulation systems. Its 1100 W three-phase motor runs at 2900 rpm, delivering a flow of 8 m³/h and a head of up to 18 m. The wetted parts are made of cast iron and withstand pressure and wear, while the motor housing is aluminium, which lets a heated pump cool down quickly. Its ability to handle hot water up to 104 °C allows installation directly in boiler rooms and heating circuits.

Advantages

• Three-phase 380 V motor — delivers stable, powerful operation in industrial conditions
• 18 m head and 8 m³/h flow — fully circulate tall systems with long circuits
• Aluminium upper housing, rear cover and bearing housing — dissipate heat quickly and keep the pump from overheating
• Full copper winding — improves motor durability and extends service life
• Bearing assemblies at both ends — keep the shaft running true and centred, reducing vibration
• Cast iron mid housing, wetted parts and impeller — withstand high pressure and prolonged wear
• Heat-resistant shaft seal — maintains a tight seal when running hot water
• IP55 protection rating and 155(F) insulation class — protection against dust, splashing water and overheating
• Matching 32 mm inlet and outlet — connects straight to the pipeline without adapters

Application

Used to circulate hot water through heating circuits and to keep water moving in hot water supply networks. Widely used in industrial zones, boiler rooms, multi-storey residential buildings, offices and production facilities, in both heating and cooling systems.

Note on use

The pump is always connected to the 380 V supply through a circuit breaker and a magnetic starter. Without protective gear, the loss of one phase or any other fault will burn out the motor. Properly installed protection significantly extends the pump's service life.
