Pedrollo Presflo Multi- Automatic Control device

The Pedrollo Presflo Multi is an advanced automatic control device. It is designed for managing single-phase electric pumps. This device supports domestic applications where automatic pump control is essential. It can handle pumps with a power rating of up to 2HP (1.5kW).

Ensuring reliable pump operation without the need for a traditional pressure tank. It starts and stops the pump automatically. This happens based on water demand from the system. When a tap is opened, the pump starts. When water stops flowing, the pump shuts off.

The device monitors both flow and pressure within the system. It includes built-in protections to prevent pump damage. One key feature is dry-run protection. If the water supply is interrupted, the device stops the pump. This prevents overheating and possible pump failure.

Restarting after a dry-run event is automatic. The device attempts several restarts at timed intervals. If water returns, it resumes normal operation. If not, the pump remains off, protecting the motor.

The Presflo Multi is also equipped with an anti-jamming system. This system briefly activates the pump every 24 hours. This helps prevent the impeller from seizing during long periods of inactivity.

Another feature is the integrated pressure gauge. This provides easy monitoring of system pressure. The gauge is clearly visible on the front of the unit.

The device includes an adjustable cut-in pressure setting. This allows customisation based on the specific application. Users can fine-tune when the pump starts during use.

The Presflo Multi works well in systems with long pipe runs. It maintains consistent water pressure across varying distances. This makes it ideal for multi-story homes or buildings with multiple water outlets.

The device is compact and easy to install. It mounts directly onto the pump or pipework. Electrical connections are straightforward, with clear labeling.

It has a strong, durable casing made from high-quality materials. This ensures a long service life even in demanding environments. The unit is splash-proof with an IP65 protection rating.

The electronic board is protected against power surges. This is especially useful in areas with unstable electrical supply. Overcurrent protection helps prevent damage from electrical faults.

LED indicators on the front panel provide system status at a glance. They display power status, pump operation, and any fault conditions. This simplifies diagnostics and maintenance.

The Presflo Multi is compatible with a wide range of pump brands. It is suitable for use in homes, gardens, and irrigation systems. It can also be used in small commercial setups.

The device helps save energy by running the pump only when needed. It eliminates the constant cycling that occurs with traditional pressure switch systems.

Noise is reduced as the pump runs less frequently. This makes the system more pleasant to use in quiet environments.

Maintenance requirements are minimal. There are no mechanical parts like membranes or pressure switches that need regular replacement. This reduces downtime and maintenance costs over time.

The Presflo Multi is compliant with Australian safety and performance standards. It is manufactured by Pedrollo, a trusted name in pump technology. Their products are known for reliability and innovation.

In summary, the Pedrollo Presflo Multi is a smart, automatic control device. It protects and enhances the performance of domestic pumps. With its compact design and advanced features, it is a practical solution for modern water systems.

Whether used for home water boosting or garden irrigation, it offers peace of mind. Reliable operation, efficient protection, and user-friendly design make it a valuable addition to any pump system.
