Leo GP-2E
Pressurization System
With Inverter PDM30 230V

Leo GP-2E - Single Phase Inverter Pressurization System

The Leo GP-2E 230V inverter pressurization and lifting system represents a technologically advanced solution for water distribution in civil, industrial and agricultural environments. Designed to ensure constant pressure in water systems, this group of electric pumps is ideal for applications where reliability, energy efficiency and intelligent flow control are required. Composed of two monobloc electric pumps (horizontal or vertical), each equipped with a PDH30 inverter , the Leo GP-2E system is mounted on a compact base in painted sheet metal and equipped with manifolds, valves, sensors and protection devices.

The 230V single-phase inverter configuration allows you to power motors up to 2.2 kW, easily adapting to domestic users or small industrial installations . The set of mechanical and electronic components ensures continuous operation, even in the event of a unit failure, and protects the system from pressure or electrical anomalies, improving overall reliability and reducing consumption.

Functional specifications

Leo GP-2E System Structure

The Leo GP-2E pressurization group is assembled on a base made of press-formed sheet metal with epoxy paint , on which two monobloc electric pumps are installed. The pumps can be horizontal (EMH or 2AC series) or vertical (EVP or LVR series), depending on the system needs. Each pump is associated with a PDH30 inverter , which can be mounted directly on the engine or on dedicated supports. The set is completed by suction and delivery manifolds in AISI 304 stainless steel , equipped with shut-off and check valves, pressure gauges, pressure transducers (4-20 mA) and fittings for 25 L membrane tanks.

PDH30 inverter for control function

The 230V single-phase PDH30 inverters allow you to power electric motors connected in delta, up to a power of 2.2 kW. These devices regulate the frequency and output voltage to adapt the pump speed to the water requirement, maintaining a constant pressure. Available functions include automatic stop via level float, timed or remote control operation and automatic switching from one inverter to another in the event of an error or signal interruption, thus ensuring continuity of service.

Applications and advantages of an inverter pressurization system

A pressurization system is designed to keep the water pressure in a distribution network stable, regardless of flow rate variations or the number of active users. The pumps, controlled by inverters and regulated by pressure transducers, increase the incoming water pressure and distribute it evenly. When demand decreases, the inverter reduces the motor speed to avoid wasting energy. In the event of a pressure drop below the set limit, the system reacts by increasing the power of the pumps until the balance is re-established. Suitable for:

• Resistance buildings
• Industrial plants
• Greenhouses
• Irrigation systems
• Structures with constant pressure requirements
