Pump Controls and Floats

Our Pump Control Box model H8 is applied for automatic liquid level control, pressure control and protection for deep well submersible pump /borehole submersible pump / pipeline pump with AC220V / AC230V / AC240V 50/60 HZ (at option), single phase, 0.37-2.2kw (0.5hp-3hp), direct start type.

Pump Control Box Model H8 measures the actual motor power (watts), not motor amps or power factor. The motor power draw at the moment of calibration is permanently memorized by H8. If the
calibration power by more than ±25%, H8 will turn off the pump motor. It is very important to make sure the pump system is running normally during the calibrating process.
