WITA Delta HE light 60-25-180 – circulation pump
Code: DHEL0002HWProduct detailed description
The WITA Delta HE light 60-25-180 pump is designed for those who want to reduce the electricity consumption of the circulation pump without losing hydraulic performance. According to the model designation, it provides a head of 6.0 m, a DN 25 connection, and a mounting length of 180 mm. The maximum flow rate reaches 3 600 l/h, the power consumption ranges from 4 to 42 W, and the EEI value is ≤ 0.20.
Standard pumps typically account for 10 to 15% of electricity consumption in an average household. According to the manufacturer, high-efficiency WITA pumps reduce this by approximately 80%, while the hydraulic performance remains almost the same as with standard pumps.
What the pump offers
- EC motor with permanent magnets for maximum efficiency
- eight characteristics (four constant, four proportional), which can be selected with a single touch
- pre-set control modes – constant speed or variable differential pressure
- Anti-block function
- built-in motor protection
- high safety at start-up
- practical key-based mounting for easy installation on the pipe

Materials and accessories
The valve is cast and finished with a cathodic coating, and the other material used is chrome-nickel steel. According to the manufacturer, this combination ensures high durability and allows for versatile use. For the 180 mm installation length, the pump body is made of grey cast iron with a cathodic coating. The delivery includes thermal insulation covers, gaskets, connecting plugs, or permanently installed cables.
Application and installation
The pump maintains forced medium circulation in the piping system. It is suitable for a medium temperature of +5 °C to +110 °C and a system pressure of up to 10 bar. The ambient temperature can be from 0 °C to +40 °C. The 180 mm length is particularly important when replacing an old pump – the installation length must match the space in the pipe where the pump is to be installed. During installation, observe the flow direction indicated on the body.
