INDUSTRIAL PROCESS PUMP

ZLN, ZLK, ZLI

ZLN, ZLK, ZLI industrial process pumps are suitable for temperatures up to 170°C (338°F). This diverse range of general purpose pumps offers the user a low life-cycle cost solution. Capital cost, power consumption, maintenance, reliability and waste, have all been considered during the extensive development phase.

ZTN / ZTK / ZTI

Operational safety, environmental concern and long-term reliabilty, are the three aspects which make this pump an ideal choice for thermal oils up to 350°C (662°F). High-end hydraulic efficiency is complimented by almost maintenance-free operation, in which to give a low Life-Cycle cost solution. Shaft sealing can be either a combiniation of mechanical and secondary lip seals.

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.
