Walrus - Model TPHIC Series - TPH8T2KSIC -Constant Pressure Inverter Control System

The pump will start smoothly when water is consumed. The inverter controller has a pressure sensor to detect down-stream pressure and adjust the motor speed to keep it at the required psi.

Constant and stable pressure control

The pump will maintain a constant operating pressure at the pressure setting. This ensures a stable water supply even though occasionally the output .ow is over the capacity.

Dry-run protection

The pump will automatically shut down to protect against dry running. Once the pump starts to operate, the pressure sensor will automatically detect the pressure limit.

Automatic stop when flow stops

The pump will automatically cycle down as water usage decreases.

Pressure compensation for pipeline leaks

Should the down steam pressure drop due to leaks in the piping system, the microcomputer will detect the pressure loss automatically and operate the pump to maintain the pressure setting limit.

Single or parallel unit operation

Parallel operation: When water usage is low, one unit will begin to operate until the water usage increases, when it can no longer handle the required water pressure, the other unit will start functioning in parallel. The duplex unit will switch to single unit operation automatically with the decrease in water demand.

Interchangeable operation

When a pump has operated through the preset interval (adjustable at 0-24 hours) the system will automatically switch to the other unit. This cycle will continue through time.
