WITA go.future 2 40-25-180 – circulation pump
Code: 16023Product detailed description
The model WITA go.future 2 40-25-180 belongs to circulation pumps with an energy efficiency index EEI ≤ 0.20. According to the type marking, it provides a head of 4.0 m, a connection DN 25, and an installation length of 180 mm, which is suitable for locations with longer clearance gaps in the pipe. The maximum flow rate is 2 800 l/h, and the power consumption ranges from 3 to 23 W.
According to the manufacturer, standard pumps account for 10 to 20 % of electricity consumption in households. The go.future 2 series pumps can reduce this consumption by up to 80 % compared to conventional circulation pumps. The hydraulic performance is almost the same as standard pumps, and the pump adapts to the current system requirements, as it operates according to the proportional pressure method.
What is included in the equipment
- 5-year warranty
- night mode
- display of current energy consumption
- anti-blocking function
- also available in a version with a PWM module

Application and installation
The pump creates a forced circulation of the medium in the pipe circuit. When replacing an old pump, it is important that the installation length of 180 mm and the connection DN 25 match. The medium temperature can be +5 °C to +110 °C, the system pressure is maximum 1.0 MPa, and the degree of protection is IP 42. The pump is connected to a voltage of 1 x 230 V, 50 Hz; separate motor protection is not required.
