WITA Delta HE light 60-25-130 – circulation pump
Code: DHEL0008HWProduct detailed description
The circulation pump WITA Delta HE light 60-25-130 belongs to the series of high-efficiency pumps with an EC motor with permanent magnets. The type designation indicates a head of 6.0 m, a connection DN 25, and an installation length of 130 mm. The pump can handle a flow rate of up to 3 600 l/h while consuming only 4 to 42 W.
Standard pumps account for an average of 10 to 15 % of total electricity consumption in a typical household. According to the manufacturer, using high-efficiency WITA pumps can save approximately 80 % of this energy compared to a standard circulation pump, while the hydraulic performance remains almost the same.
Advantages and features
- menu with one-touch control and eight performance curves – four constant and four proportional
- predefined control modes: constant speed or variable differential pressure
- highest efficiency thanks to the EC motor with permanent magnets
- Anti-block function that prevents the pump from blocking
- integrated motor protection
- high safety at start-up
- easy installation on the pipe with key-based fastening
Construction and delivery
WITA chooses cast pump casings with a cathodic coating and chrome-nickel steel for its pumps. These materials ensure high durability and versatile use. The body of the version with a length of 130 mm is made of grey cast iron with a cathodic coating. The delivery includes thermal insulation jackets, seals, connecting plugs, or permanently installed cables.

Application and installation
The pump creates a forced circulation of the medium in the pipe network and is suitable wherever a standard circulation pump unnecessarily consumes too much electricity. The medium temperature can range from +5 °C to +110 °C, and the system pressure can reach up to 10 bar. When replacing an old pump, check whether the DN 25 connection and the 130 mm installation length match. When installing, follow the flow direction arrow on the body and insulate the pump with thermal insulation jackets after installation.
