The safe handling of hot liquids has always been one of the main priorities for our represented DICKOW PUMPEN.
DICKOW PUMPEN launches a new generation hot water circulation pump on the market for use in medium and large hot water systems. The new NHX series pumps are designed for severe processes and use DICKOW PUMPEN's patented cooling/degassing system. In this way, a moderate temperature in the bearing housing and a stable liquid film in the mechanical seal groove are guaranteed, avoiding high temperatures of the antifriction bearing under extreme load conditions.
Hydraulic performance and dimensions conform to ISO 2585.
The pump is interchangeable with the NHL models, with cooling by finned tubes, in addition to meeting the technical requirements, according to the ISO 5199 standard for handling hot water.
