Our DEA.C 20-30 pump is equipped with a semi-open impeller with a diameter of Ø150mm that can be reduce until 125mm. In our DEA.C20-30 standard version we install a single mechanical seal (we can also install a double flushed mechanical seal) composed of Stainless Steel AISI 316 / Graphite / EPDM that allows to tansport the major part of the liquids that are compatible with EPDM seals and that don’t reach a temperature over 90°-100° C degrees. The connections of this pump are according the DIN 11851 Standard and their size is DN50 for the inlet manifold and DN40 for the outlet manifold; as you can image, the connections can be easily changed with other fitting according with other standards like SMS, Clamp, Bsp or even Flanges. This size of pump can be equipped with only two sizes of electrical engine both 2 poles and 4 poles with 2,2Kw and 3,0Kw. The amazing thing about our pumps is that they can be sold without engine as long as the engine connection is according the IEC 90 B5 Standard and IP55 50/60Hz 230/400V.
