Pump or alarm start/stop control in lift stations and wastewater pumping stations.
Its compact size makes it particularly suitable for small spaces.

The NIVOSTOP HP4 detector is specially designed for use on clean or waste water, in small spaces and/or at relatively great depths (up to 40 meters).

The operating principle remains similar to that of the other products in the NIVOSTOP range, except that the ballast is not integrated into the envelope. The latter is optional and its use will depend on the application and service conditions.

Under the thrust of the fluid, the tilting of the float activates a contact connected to a control panel. Its fixing point, the added counterweight and the length of the cable make it possible to adjust the ON-OFF for switching in a small space.

The Nivostop HP4-xx-H05 features a large-diameter cable and a reinforced sealing system (two envelopes) for maximum durability and reliability in harsh environmental conditions.

Two shells to protect the switch:

1. First sealed chamber
2. Second sealed chamber
3. Final thermoplastic seal :
4. EPDM rubber cable gland: tested at 5 bar

Counterweight (230g) :
It allows the float switch to operate with the same cable length at all times, even in turbulent waters, avoiding damage to the cable. It also stabilizes the movement of the float switch and effectively tracks level changes.
