Repairing the Pump

Overview about the Nano Pump

Figure 13 shows the main assemblies of the nano pump. The pump heads and
its parts do require normal maintenance (for example, seal exchange) and can
be accessed from the front (simple repairs). Replacing internal parts will
require removing the module from its stack and to open the top cover.
