PUMP GRUNDFOS UPM3 HYBRID 25-70 130

The UPM3 are speed-controlled, high-efficiency pumps equipped with an electronic commutation motor (ECM), permanent magnet rotor and frequency converter. They can be controlled externally via a low-voltage digital PWM (Pulse-Width Modulation) signal, LIN bus signal or internally controlled in constant pressure, proportional pressure or constant speed mode defined by a control panel or factory preset. The product is suitable for pumping clean, thin, non-aggressive and non-explosive liquids, not containing solid particles or fibres. In heating systems, the water must meet the requirements of accepted standards for water quality in heating systems, for example the German standard VDI 2035.
