Name: ITWZB Series Automatic Multi-protection Double Control System Intelligent Self Primning Pump
Brand: Taizhou Edwin Electric Co., Ltd.

Function :

The linear pressure sensor is employed to regulate the initial pressure of the pump rather than conventional mechanical switch. Concurrently, it incorporates an advanced flow control system.
The capabilities of the pump comprise :
1. Automated recognition of pipe pressure;
2. Automatic readjustment of starting pressure;
3. The integrated chip possess a memory function;
4. Plug-and-play configuration;
5. Intelligent adaptable learning;
6. The operation of water pump is governed by the pressure sensor and flow switch.;
7. Water deficit protection mechanism;
8. Initiates the pump automatically when the water returns;
9. Timer functionality;
10. Temperature protection;
11. Electrophoresis for rust prevention.
