STEADY PRES Electronic Variable Speed Pump Controller


Electronic variable speed pump controller with inverter technology for single and multi-pump applications up to 2,2 Kw per pump.

STEADY PRES features a techno polymer body suitable for potable water and its low pressure losses make it suitable for use with pumps with flow rates up to 200 litres/min.

Signal board (optional).

The Input/Output signal board is fitted in the back of the unit and includes connections for:
– RS485 Communication signal for use with multi-pump installations
– Float switch (or other input signal): allows the connection to a level sensor or other switch for remote start-stop signal.
– Alarm Output for remote alarm

Installation – Start-up:

Installation and service – is simplified by the two ‘quick release’ union fittings supplied.
Electrical connection: easy and safe thanks to the removable connector.
Start-up: You only need to select the required operating pressure and the rated current of the pumps.


STEADY PRES stands out for the quality of its electronic components and for the following features:

– Integrated pressure sensor, robust and easily accessible
– Flow sensor – complete with check valve able to sense flows down to only 2 lt/min.
– Heat dissipation – Heat emission is a characteristic of all inverters when they are working and its dissipation is extremely important for reliability. STEADYPRES keeps its cool thanks to a metallic heat sink with large cooling ribs in direct contact with the water flow.
