Description

PW-S series automatic self-priming pumps have flow switch, pressure switch and PCB board.

It can collect flow and pressure data by flow switch and pressure switch, then make data analysis by PCB board and automatically give order to be on or off, in this way, the water pump will supply water stably.

This pump have several functions, like 3 seconds delay after start-up, water shortage protection, standby anti-interference and so on.
