WITA® Circulation Pumps – Quality, Technology and Energy Efficiency

All products in our series of circulation pumps share one common feature – they use high-quality technology, offer excellent workmanship, and provide numerous user benefits.

WITA® products are made from cast fittings coated using the cataphoretic method and from chrome-nickel steel. These proven materials ensure high durability and a wide range of applications. All circulation pumps are supplied with thermal insulation jackets, gaskets, caps, and permanently mounted power cables.

In an average household, standard pumps can consume between 10 and 15% of total electrical energy. By using energy-efficient WITA® pumps, energy consumption compared to traditional circulation pumps can be reduced by up to 80%. At the same time, their hydraulic performance remains comparable to that of standard pumps.

Thanks to the One Touch function, up to nine different power curves can be selected. In addition to four curves based on the proportional pressure method, there are also four curves with constant speed characteristics. The pump also features a minimum operating level mode.
