STEADYPRES Inverter Drives

The STEADYPRES is a variable frequency drive control systems for electric water pumps. This consists of: a built in pressure sensor, a flow sensor and an inverter all in one unit. The box is compact and very easy to install.


The STEADYPRES can work with any kind of pump: multi stage or single stage, surface or submersible. STEADYPRES uses the built-in inverter to control the speed of the motor, maintaining a constant pressure in the system. As the flow increases, the speed of the motor increases, maintaining a constant pressure.
