Circulation pump Weberman Pompa CO 32-80-180 (0401W) — inline circulator 32/80/180 mm

Weberman Pompa CO 32-80-180 (0401W) is an inline circulation pump engineered for use in heating and hot-water systems. With a nominal diameter of 32 mm and a compact body length of 180 mm, this pump provides continuous water circulation in boilers, radiators and closed hydronic circuits. Its maximum head of 80 mbar (0.8 m) suits low-to-medium resistance systems, helping to maintain stable flow rates and even temperature distribution across connected components.

Advantages

The pump combines a compact inline design with straightforward hydraulic characteristics, allowing integration into existing pipe runs without major layout changes. Its specified diameter and length reduce the need for additional fittings, and the modest maximum head limits energy use in systems where high pressure is unnecessary. Designed for circulating water, the unit supports reliable continuous operation in residential and light commercial heating circuits.

Suitable for

• Circulation of hot water in domestic and small commercial heating systems
• Feeding radiators and convectors within closed hydronic loops
• Boiler loop circulation and primary-secondary circuits with low to moderate pressure drop

Key specifications

• Nominal pipe diameter: 32 mm
• Maximum head (pressure lift): 80 mbar (0.8 m)
• Nominal installation length: 180 mm
• Design type: inline circulator for closed hydronic systems
• Fluid compatibility: water for heating and hot-water systems (closed circuits)

How to use

Install the pump inline in the return or supply pipe according to the system hydraulic plan, ensuring flow direction matches the arrow on the pump body. Connect to appropriate thread or flange fittings of the same nominal diameter, secure electrical connection following local regulations and cut power before servicing. Purge air from the circuit after installation and set operating controls of the heating system to achieve the desired circulation rate. Regularly check seals and connections for leaks and ensure the pump operates within the specified maximum head.

Usage recommendations

Use the Weberman inline circulator in closed hydronic systems with clean water and installed filtration if required. Avoid dry running and prolonged operation outside intended pressure/head conditions. Schedule periodic inspection for wear, ensure electrical protection and follow national wiring standards when connecting the unit.
