Circulation pump ESN40-25-3 (3000W)

Circulation Pump EPA ESN40-25-3 (3 kW)

This is a three-phase industrial circulation pump for heating and water circulation systems. It runs on a 380 V supply with 3 kW of power, and the motor turns at 2900 rpm. The pump moves 20 m³ of water per hour, provides 25 m of head and handles water up to 104 °C. The connection diameter is 40 mm.

Advantages

• Three-phase 380 V motor — steady, powerful operation in industrial conditions
• 20 m³/h throughput and 25 m head — even water circulation in large heating systems
• Water temperature up to 104 °C — long operation with hot water
• Aluminium upper housing, rear cover and bearing seat — dissipate heat quickly and prevent the pump from overheating
• Solid copper winding — increases motor durability and service life
• Double-sided bearing assemblies — keep the shaft running true and reduce vibration
• Cast-iron middle housing, wetted parts and impeller — withstand high pressure and long-term wear
• Heat-resistant shaft seal — stays watertight when working with hot water
• IP55 protection and 155(F) insulation class — protected against dust, splashes and overheating

Application

Used to circulate hot water at industrial sites, in multi-storey buildings and in large heating systems. Intended for industrial facilities and farms.

Note on use

The pump must always be connected to the 380 V supply through a circuit breaker and a magnetic starter. Without protective equipment, losing a phase or any fault will burn out the motor. Correctly installed protection significantly extends the pump's service life.
