Energy-saving electronic glandless circulating pump designed for all types of domestic heating, ventilation and air conditioning systems. The IPX5 degree of protection prevents the ingress of moisture into the mechanical parts and electronics. The possibility of failure is reduced to a minimum. Ensuring trouble-free operation. The new user interface with backlit display and sequential operating button allows for quick reading and easy entry of settings under all conditions. Swapping pumps is now extremely easy: the new universal connector can be used with power plugs for pumps from other manufacturers, without the need to modify electrical connections. Thanks to optimized energy consumption and the use of a frequency converter, the energy efficiency of the new EVOSTA 3 pump is even higher and has a low coefficient.
