Caleffi Pump Station 25mm
The direct supply unit performs the function of supplying the heating system circuits at high temperature.
Complete with high-efficiency pump, flow and return temperature gauges on secondary circuit, secondary circuit shut-off valves, pre-formed shell insulation.
The unit is reversible: in fact, the flow direction can be inverted from right to left, depending on installation requirements. This unit can be coupled to the 559 series SEPCOLL separator/distribution manifold for systems that require hydraulic separation or the 550 series distribution manifolds for systems with buffer tanks.
