Speroni Controller Pump Auto 25mm 10A 1.1Kw 230V

Speroni Automatic Pump Controller (1.1kW / 230V / 10A)

The Speroni Automatic Pump Controller is a high-precision electronic command module engineered for the automated management of surface and submersible water pumps. Designed to replace traditional mechanical pressure switches and expansion tanks, this "constant pressure" controller utilizes integrated flow and pressure sensors to start the pump when a tap is opened and stop it when the flow ceases.

Technical Engineering and Automated Logic

• Intelligent Start/Stop Sequencing: The controller is programmed to activate the pump when the system pressure drops below a pre-set starting threshold (typically 1.5 Bar). It maintains pump operation as long as there is a minimum water demand, ensuring a consistent, non-fluctuating flow of water to the discharge point.
• Integrated Dry-Run Protection: A critical mechanical safeguard, the Speroni controller automatically shuts down the pump if it detects a lack of water at the suction inlet. This prevents the motor from overheating and the internal impellers from seizing due to dry operation—an essential feature for borehole and rainwater harvesting systems.
• Automatic Reset Function: Following a dry-run shutdown, the unit is programmed to perform periodic restart attempts. This "intelligent retry" logic allows the system to resume normal operation automatically once the water supply is restored (e.g., after a borehole recovers or a tank is refilled).
• Anti-Cycling Software: The electronic board is designed to minimize "hunting" or rapid on/off cycling, which can occur with minor leaks in the plumbing. This extends the operational lifespan of the pump's motor windings and start capacitors.

Material Integrity and Electrical Specifications

• High-Impact Thermoplastic Housing: The internal electronics are encapsulated in a rugged, UV-stabilized polymer casing. This provides an IP65 ingress protection rating, making the unit resistant to dust and low-pressure water jets, which is a requirement for outdoor pump installations.
• 1.1kW / 10A Power Rating: Specifically calibrated for single-phase 230V motors. This controller can directly manage pumps up to 1.5HP (1.1kW) without the need for additional contactors or relays.
• Corrosion-Resistant 25mm Ports: Features standard 1-inch (25mm) Male BSP threaded inlet and outlet ports. The precision-molded threads ensure a high-pressure, leak-proof connection to standard PVC, HDPE, or galvanised steel piping.
• Built-in Non-Return Valve (NRV): The internal geometry includes a spring-loaded check valve. This prevents backflow and maintains static pressure within the household plumbing when the pump is in standby mode.

Operational Utility and Applications

• Domestic Pressure Boosting: The primary solution for increasing municipal water pressure in residential homes, ensuring strong flow for showers and high-end appliances.
• Agricultural and Garden Irrigation: Ideal for controlling pumps in automated irrigation systems, nurseries, and livestock watering troughs where a reliable, automated water supply is required.
• Borehole and Tank Management: Serves as the central "brain" for systems drawing from subterranean sources or storage tanks, providing essential protection against pump damage.
