Everline 25/4/180 Circulation Pump

Product detailed description

The Everline 25/4/180 circulation pump has a longer 180 mm installation length, covering the same performance range as the 130 mm model, but it is suitable where the system has an older pump fitted with a wider spacing of flanges or threads.

Key features:

• Connection G 1½" (DN25), installation length 180 mm
• Head 4 m, flow rate 48 l/min (2.88 m³/h)
• Three-speed output control according to the current needs of the system
• Robust cast iron body with a ceramic shaft and ceramic bearings for a long service life
• Quiet and energy-efficient operation

A 4 m head is sufficient for small and medium-sized heating systems with radiators or underfloor heating.

What is the difference between the 130 mm and 180 mm version at the same output?
Only the installation (fitting) length of the pump between the threads differs – the hydraulic parameters (head, flow rate, power input) are the same for the 25/4/130 and 25/4/180. Choose the version according to the length of the original pump.
