Product information

Description

The WILO ATMOS PICO 25/1-4 180 circulation pump is intended for closed hot-water heating systems. Its compact construction and axial-flange connection make it suitable for retrofit and new installations where space is limited. The pump is designed to provide continuous circulation of heating water with a focus on energy efficiency and quiet operation, offering stable hydraulic performance for residential and small commercial heating circuits.

Advantages

The pump combines a small footprint with high pumping efficiency and low electrical consumption. Robust construction and corrosion-resistant wet rotor materials ensure long service life, while a simple flange connection and standardized dimensions simplify installation and replacement. The design reduces noise generation and vibration during operation, and maintenance requirements are minimal thanks to an easily accessible motor and wet-running design.

Suitable for

  • Domestic radiator and underfloor heating circuits
  • Small commercial heating systems
  • Boiler circulation and heating zone pumps
  • Retrofit replacements in confined installation spaces

Key specifications

  • Pump type: single-stage centrifugal circulation pump for heating water
  • Connection: axial flange connection suitable for standard heating pipework
  • Maximum head: designed for low to medium head applications (appropriate for typical residential systems)
  • Flow characteristics: optimized for low-flow, high-efficiency circulation
  • Motor design: wet rotor for compactness and reduced maintenance
  • Noise level: low operational noise due to balanced rotor and casing design
  • Materials: corrosion-resistant hydraulic components for durability in heating water
  • Mounting: compact footprint for horizontal or vertical installation as system layout requires

How to use

Install the pump in the return or flow line of a closed heating system following local plumbing and electrical regulations. Ensure correct pipe alignment and secure flange connections to avoid leaks. Connect the electrical supply according to the motor nameplate and wiring instructions provided by the pump manufacturer. Prime the system and remove air from the circuit before regular operation. Verify pump rotation where applicable and check for leaks and abnormal noise during initial startup.

Usage recommendations

For optimal performance, use the pump in systems with properly sized piping and balancing valves. Regularly inspect the system for air ingress, scale build-up and debris that can affect hydraulic performance. If the system contains aggressive or heavily contaminated fluids, select appropriate filtration and water treatment measures. Follow local service intervals and replace the pump if performance drops significantly or if mechanical wear is detected.
