4 Features
The PC-58 unit is a digital pressure control for water pumps. It starts and stops the pump according
to the detected data of water flow in the pipe and water pressure. It completely replaces the
traditional pump control system, which consists of a pressure tank, pressure switch, water shortage
protection device, check valve, etc. The electrical components are completely isolated by piping and a highly
sealed control box, which increases the safety of the unit beyond comparison with the traditional safety
system. The integrated design helps you save time and material. Compared with traditional electric pressure
control, this product has the following important features:
1. It has a new pressure sensor technology, thanks to the digital display, the unit can display the pressure
in the pipe in real time.
