Pump groups are pre‑assembled hydraulic assemblies built for hydronic heating systems, integrating circulation pumps, valves, measuring gauges and thermal insulation for fluid circulation and temperature management. They deliver stable heat distribution, precise temperature adjustment and reliable hydraulic separation, supporting multi‑zone heating demands for residential, commercial and renewable‑energy heating projects. Compact pre‑mounted structure cuts on‑site piping work, while high‑efficiency components lower heat loss and running consumption. Built‑in protective fittings guarantee secure continuous operation, offering flexible, time‑saving solutions for under‑floor heating, boiler and heat‑pump heating setups.
