8.5 Connecting a leakage drain 8.4.2 Making the glue-in connection Neptune dosing pumps are produced to the highest of quality standards with a long service life. However, some parts are subject to operational wear. This is the case particularly with the diaphragms that are continu- ously subjected to forces during the suction and discharge strokes and to the effects of the dosing medium.
8.7.2 Pressure-relief valve Pressure relief valves have an important safety function for protecting the NSP-M dosing heads have an integrated dosing head venting facility. dosing pump and the associated pipes and fittings. The dosing pump can generate a pressure that is many times the rated one. A blocked pressure line can lead to dosing medium escaping.

Level monitoring of suction-side feeding of the dosing medium to prevent When using long pipes (the severity of the pulsation increases with the tank being sucked dry and to ensure that it can be topped up again in the length of the pipe).
NOTE into the plant safety concept. Conductive rubber band The NSP-M is delivered with a conductive rubber band connected CAUTION in the connection port. The band conducts electricity and ensures that the contact in the connection port remains closed when no Danger of automatic start up! cable is connected.
