Industrial Process Pumps - ZHN, ZDN, ZEN, ZDI


Superior hot water circulation, up to 230°C (446°F) with a standard un-cooled mechanical seal, gives the unique ability to minimise life-cycle cost. Internal separation and removal of undesirable vapour (steam) enhances mechanical seal face lubrication and improves reliability. High-level hydraulic efficiency ensures that running cost are predictably low.
