Constant Pressure Pump Controller

Ausenist manufactures constant pressure pump controllers and water pump VFDs for booster pumps, building water supply, irrigation and industrial pumping systems.

Our inverter solutions support pressure sensor feedback through 0–10V and 4–20mA signals.

How Constant Pressure Control Works

A pressure sensor measures water pressure and sends a feedback signal to the inverter.

The inverter automatically adjusts pump motor speed.

When water demand increases, pump speed increases.

When demand decreases, pump speed decreases.

When demand becomes very low, the system can enter sleep mode.

When pressure drops again, the pump can restart automatically.
