ZSP-3 – Level signaling set

For cooperation with our SPP control cabinets, we recommend the ZSP-3 level signaling set, consisting of:

1. Float level switch, the so-called Float – 3 pcs. (10m cables)
2. Chain Ø3 DIN 763 stainless steel A4 – 1 pc. (4m)
3. Shackles Ø4 long, stainless steel A4 – 2 pcs.
4. Stainless steel hook Ø10 stainless steel A2 – 1 pc.
5. Cast iron chain weight – 1 pc.

• Upper Float Alarm – signals that the permissible level of sewage in the tank has been exceeded and activates optical and acoustic signaling on the control cabinet housing.
• Middle Float Start/Stop – responsible for the active volume (retention) in the tank. The length of the float should be selected according to the assumed level of switching the pump on and off. Minimum working length of the float ~15cm (due to the possibility of bending the cable).
• Lower Float Dry running – provides a level of protection for the pump against overheating and air in the pump.
