Safely and Precisely Delivering Ammonia Solution

A continuous mixing unit consisting of several static mixers is supplied with eight liquids of different viscosities.

Micro annular gear pumps of the hermetically inert series and the high-performance series from HNP Mikrosysteme are used for the smaller volume flows of highly corrosive liquids. Aqueous ammonia (NH3 25 % aq.) is a special technological challenge.

Here the hermetically inert pump mzr-6355-cs works in a material combination of ceramic and stainless steel. In this application, the micro pump delivers volume flows between 4 and 7 ml/min.

The system produces mixtures with different polymer concentrations. The volume produced is controlled based on the customer’s daily delivery requirements. The continuous mixing system is fully automated.

It can be easily connected to the site’s local IT systems, such as SAP. Continuous and highly precise delivery with micro annular gear pumps thereby ensures a process that is fast, flexible and safe.
