Circulation pump with frequency regulation VRS 25/6EA-180

(VRS.256EA.18) The VRS EA circulation pump has an electronic frequency converter, which automatically changes revolution speed of the rotor according to the selected mode of regulation (possible options: 1-Maintaiing constant pressure 2-Pressure alteration according to consumption). Such pumps are most effective from the point of view of saving power and maintaining hydraulic stability in the heating system.

The VRS EA pumps can also operate under minimum capacity conditions (“Night”) and as normal three-speed models. The pump can be controlled from the control panel, which is fitted on the pump’s body.

The VRS EA pump has classical wet rotor design. This pump’s additional advantages include the use of modern materials (ceramic material with smooth finished surface, stainless steel, highly glass filled polypropylene) and a number of technical modernizations, included in its structure.

Circulation pump VRS EA with frequency regulation can be used with open and closed heating systems, with maximum working medium temperatures of 110°C. Maximum static pressure – 10 bar.

Diameter of nominal passage – 2 5 mm. Maximum pressure (at zero consumption) – 6 m H2O. Installation length – 180 mm.

The connector nuts and cable (115 cm, with plug) are included in the package.

The pump is equipped with an overheat protector cutting off the power supply when the temperature of the stator winding is exceeds 150 °C. Subsequent pump activation is only possible after cooling of the winding.
