Application

It is suitable for automatic control and protection of direct-start stainless steel/cast iron deep well submersible pumps , centrifugal pumps , pipeline pumps , etc . It is especially uniquely designed to realize sensitive and reliable pump dry-run shutdown protection function without installing a sink (well) probe , which is more convenient for the construction and installation of deep well submersible pumps and pipeline pumps and saves costs.

Main features

With open phase ,stalled ,over current , Dry run ,Over/ under voltage protection function on Both manual and auto mode . It can realize automatic control by liquid probe , pressure tank , and float switch.

Optional

WIFI/4G module available . You can control the pump remotely via Mobile app with real time .

Troubleshooting

Concise troubleshooting guide

Water pump cloud platform remote monitoring

Users can search/add/share/control and monitor water pumps through mobile APP and PC. remote monitoring of pumps Start/stop; fault/normal of the water pump; manual/automatic of the water pump; current , voltage , power, water level , pressure , etc . of the water pump state . When a fault is detected in the water pump , it will record the fault of the water pump , generate a pie chart and a report , and push an alarm prompt to help The monitoring center and maintenance personnel know the situation of the pump in time . The pump data report supports the printing function , which is convenient for troubleshooting after the event Analysis and Diagnosis .
