The Archergas 25-80/180 Light Commercial is a heavy-duty central heating circulator pump engineered to provide powerful fluid movement across large-scale domestic and light commercial systems. Constructed from highly durable cast iron, the pump body is designed to resist corrosion, elevated pressures up to 10 bar and extreme thermal conditions. It delivers an impressive maximum head of over 8m alongside a sustained flow rate of 115L/min, making it suitable for extensive radiator networks, underfloor heating manifolds and air source heat pump installations. With an Energy Efficiency Index rating below 0.21, this A-rated ErP compliant pump guarantees exceptionally low running costs.

Measuring 180mm port-to-port and utilising a standard 1.5" threaded connection, it serves as a straightforward drop-in replacement for numerous legacy models, including popular Grundfos and Wilo units. The internal electronics offer four distinct modes of control, allowing engineers to balance the hydraulic circuit precisely based on pressure drops and flow requirements. Operating on a standard 230V single-phase electrical supply and sealed to IP44 standards, it ensures mechanical reliability and long-term durability in demanding utility environments.

Q: What is the maximum hydraulic head produced by this model?
A: The pump is engineered to generate a maximum delivery head of just over 8m.

Q: Is it a suitable replacement for a standard 130mm pump?
A: No, this unit features a 180mm port-to-port measurement designed for light commercial and larger domestic pipework.

Q: What materials are used for the main casing?
A: The pump housing is constructed from robust cast iron to withstand high operational temperatures and pressures.

Q: Can it be installed within an underfloor heating system?
A: Yes, it is fully compatible with underfloor heating, solar circuits and air source heat pump configurations.
