AdVANTAGES•  Anti-blocking security well protected 

The AxESS 130/Nyi 53 is well protec-ted by a particle filter that helps prevent harmful particles entering the can area. This protection is further enhanced by the uti-lization of a hollow shaft and double stream flow that reduce the possibility of deposit built up in the can area (anti-jamming, degassing of the rotor chamber).

- Automatic de-jamming system - Automatic detection of seizure. - Automatic snap-in of the highest starting torque.

• Universal: the ideal solution For most installations - 3 Pre-programmed settings allow the AxESS130/Nyi 53 to be easily set to the ideal performance requirements of the system.

- All application areas: new building, renova-tion and replacement.

- For installations: with or without thermostatic regulation valves.

- Radiators or underfloor heating.

•  Still easier: 3 pre-programmed settings - 3 Notches selection.

- Factory pre-set for the most standard installations: 80%.

- No other setting: the circulator fits auto matically.

•  Compatible with thermostatic regulating valves 

- Automatically adjusts its speed to match the ever changing system needs.

- Avoids whining of the thermostatic valves. - Reduces water circulation noise in the installation.

- Avoids the use of a differential relief valve.

• Quick fit electrical connectors - Ample space for electrical cables. - Good spacing between the 3 levers. - “Live, neutral, earth” clearly marked. - Connection holes easily accessible for ca-bles up to 2.5 Mm2.

dESIGN

• Hydaulic part- Pump casing with threaded ports for direct mounting on pipe.

- Rotating parts in contact with water made of corrosion-proof materials.

- Stainless-steel impeller neck ring.

• Motor - Wet rotor, bearings lubricated by pumped liquid.

- Rotor chamber protected by sintered bronze filter.

- Hollow shaft.
