9 Easier service and maintenance THE DESIGN The new generation N-Pumps feature numerous advanced technical solutions which together help to minimize the risk of downtime, and reduce the overall costs of your pumping operation. An inspection chamber between the seal unit and the bearings helps increase operational reliability, allowing for easy routine service checks and maintenance. A built-in sensor provides early notification of any fluid build-up in the case of a seal leakage, reducing the risk of expensive repair work. The impeller fastener is a patent pending design, making the tasks of removing, trimming and mounting the impeller much simpler and faster. Smoother, rounder design of the exterior casing keeps the pump cleaner; an increasingly important health and safety factor when servicing. Fewer external screws also make it easier to disassemble and re-assemble the pump. The Plug-in™seal unit provides a perfect fit and faster, simpler replacement. The design also protects the seal surfaces during disassembly and mounting.
