Bastion Central Heating & Underfloor Heating Circulating Pump
Professional Product Information from MEP Stock
The Bastion 25-6-130 central heating circulating pump moves heating water around compatible domestic radiator and wet underfloor heating circuits. Its manual three-position speed selector allows installers to choose the operating speed required by the heating circuit.
With a 130mm port-to-port installation length, 1½" threaded connections and a maximum 6m pump head, this circulator is an option for compatible heating pump replacements and new installations. It operates on a 230V, 50Hz single-phase supply and combines a cast iron pump body with a PEI impeller and ceramic shaft and bearings.
Key Features
- Three manual speed settings to suit the heating circuit's circulation requirements
- Maximum pump head of 6m at the highest speed setting
- 130mm installation length for compatible pump replacements and new installations
- 1½" threaded inlet and outlet connections
- Cast iron pump body with ceramic shaft and bearings
- Suitable for compatible radiator and water underfloor heating circuits
- 230V, 50Hz single-phase motor with IP44 protection
