Industrial Process Pumps - 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.
