The NESS Pump Monitoring System consists of three modules with which it measures the most important parameters – leakage (NESS NPCL), pump vibration (NESS NPCV) and bearing temperature (NESS NPCT) – during the operation of the pump. The NESS Pump monitoring system is part of the NESSessities concept which constantly increases safety, availability, durability and efficiency in thermal oil systems.

No problem at all! Like all NESSessities, also the NESS Pump Monitoring System is designed with practical orientation. The modules can be used independently from the manufacturer and are integrated in existing system control. This concept allows the relatively easy retrofitting also for already existing systems.

All-in-all 4 sensors must be integrated for monitoring. The leakage monitoring (NPCL) is a small stainless-steel container that is mounted on the base plate of the pump. Filling level and temperature are measured on this container to be able to distinguish between cold and hot filling up (pumps can have a normal leakage due to operation). The vibration monitoring (NPCV) consists of 1-2 sensors that are mounted on motor housing / or pump (depending on the design of the coupling and the maintenance strategy). The bearing temperature (NPTC) is mounted on the bearing carrier of the pump.

Because it is a modular system, it is possible to use leakage, pump vibration, or bearing temperature as a single monitoring solution. For safety-related points of view however, we recommend the complete monitoring of the parameters.

It is connected by precisions steel pipes with Ermeto screwed connection. These are included in the scope of delivery as mounting set in two different variants (depending on type of pump and the local conditions).

It is mounted to the pump by a threaded part that is included in the scope of delivery as mounting set depending on the type of pump.

The bearing temperature monitoring unit consists of a protective pipe with installed measuring elements. They reliably measure the bearing temperature and record an unwanted increase of temperature. The sensor to be mounted depends on the manufacturer of the pump and the pump size and is directly screwed in the bearing carrier.
