DAB Electronically Controlled Circulating Pump EVOSTA 3 40/130

The Evosta 3 40/130 from DAB is an electronic wet rotor circulator pump for water circulation in heating and air conditioning systems in residential buildings. It is the first circulator pump with IPX5 protection rating. The permanent magnet synchronous motor and frequency converter electronics automatically adjust the power to the system's requirements, saving energy and protecting against pressure surges. Easy setup: A sequence button allows you to scroll through the nine operating modes: three proportional pressure, three constant pressure, and three constant curve modes. All models feature a vent plug, automatic de-aeration function, and allow for manual unlocking of the motor shaft. Suction and discharge connections are threaded. Impeller made of technopolymer. Insulation shell included. Pump casing made of cataphorically treated cast iron, motor casing made of stainless steel. The Evosta 3 is equipped with a display that shows the head in meters of the selected curve, the instantaneous power consumption in watts, the instantaneous head, and the instantaneous flow rate. Thanks to the new interchangeable standard Evosta 3 plug, the device can also be operated with connections from other manufacturers without rewiring. The included lime filter cartridge keeps the motor shaft in perfect condition and prevents the common lime scale buildup that can occur during initial installation due to air bubbles inside the circulator pump. Flow rate range: 0.4 - 4.2 m3/h with heads up to 8 meters. Liquid temperature range: -10 °C to +110 °C. Operating pressure: 10 bar (1000 kPa). Protection rating: IPX5. Insulation class: F. Installation with horizontal motor shaft. Standard power supply: Single-phase 1x230 V~50/60 Hz. Pumped liquid: clean, free of solids and mineral oils, low-viscosity, chemically neutral, similar to water properties (glycol max. 50%).
