Now in hot water
29 Mar 2000
The new ZDNA and ZHNA models extend Sterling Fluid Systems' range of high temperature pumps for hot water applications.
The ZDNA long-coupled pump is suitable for hot water up to 185 degrees C. It has a single, uncooled mechanical seal and a casing pressure of up to 25bar. The ZHNA is for water up to 180 degrees C and at pressures to 16bar.
Unlike conventional hot water pumps, the ZDNA has its mechanical seal placed at the `cold end'/drive end of the shaft.
