Product Description

NO.1 About Product

Description
0.5hp-5.5hp,Duplex Pump Controller(L922-B)Push button calibration

Eliminates the need for at least 2 pressure switches or pressure gauge. Thus significant cost-savings result from dramatically reduced purchasing and clearing of pressure switch or pressure gauge;

More secure because it uses pressure transmitter, whereas pressure switch or pressure gauge often fail because of mechanical failure;

Different pressure value for starting or stop the pumps can be set via LCDscreen directly and real time pressure value displaying;
