PEDROLLO STEADYPRES Inverter with Water Passage User Guide
INSTALLATION AND USE
STEADYPRES is an inverter-based electronic control device compatible with both
surface and submersible pumps,
SINGLE-PHASE or THREE-PHASE, up to 1.5 HP (1.1 kW). Designed for domestic
water supply and irrigation, it seamlessly integrates with any pressurization
system, including existing setups, to enhance comfort, extend system lifespan,
and achieve significant energy savings.
PRODUCT DESCRIPTION
STEADYPRES is connected to the pump’s delivery system and adjusts the motor’s rotation speed by modulating the output voltage’s value and frequency. This adaptation is based on the required water flow, ensuring constant pressure within the system.
STEADYPRES components:
– electronic frequency converter (inverter);
– integrated pressure and flow sensors;
– electrical panel with keypad and LED indicators for intuitive parameter
reading;
– integrated and inspectable non-return valve;
– rear threaded connection to equip the system with a small expansion tank.
STEADYPRES protects the pump from:
※ Dry running
※ Overcurrent
※ Undervoltage
※ Overheating
※ Short circuit or current leakage
VERSATILE PRODUCT
STEADYPRES can be paired with both single-phase and three-phase pumps,
featuring internal switches for configuration settings of
※ the output frequency at 50 Hz or 60 Hz
※ the output supply voltage (single-phase or three-phase 230V )
KEY FEATURES
※ Quick and intuitive pressure adjustment via +/- buttons (1-9 bar)
※ Energy-saving with reduced pump absorption
※ Reduced noise operation
※ Minimal pressure drops
※ Extended pump lifespan
OPTIONAL
※ Expansion board enables parallel connection of up to two devices, forming pumping groups.

TYPICAL INSTALLATION
N.B.: It’s advisable to install a membrane EXPANSION
TANK (1SF) downstream of the inverter to:
※ decrease pump start frequency
※ absorbe excess pressure from the system, like water hammer
