Control unit PC-16 with pressure gauge

Product detailed description

The IBO PC-16 control unit with pressure gauge is commonly used in domestic water supply systems to manage the operation of submersible and self-priming pumps. Installers typically encounter this unit in residential settings, such as borehole water systems, surface water abstraction, and irrigation applications. The device eliminates the need for a separate pressure tank or pressure switch by integrating these functions into a single unit. It ensures continuous water supply by monitoring pressure levels and automatically restarting the pump when conditions allow. This makes it ideal for automated water management in systems where manual intervention is impractical.

When installed in a water circuit, the control unit continuously monitors the flow and pressure of the liquid. If the pump runs dry due to a lack of water, the unit shuts it down to prevent mechanical damage. Once water becomes available again, the unit initiates a restart cycle. This functionality is especially useful in irrigation systems where water availability can fluctuate. The device also includes a built-in electrical socket for connecting the pump, simplifying the installation process. For systems requiring frequent water access, the unit can be paired with a domestic water station equipped with a pressure tank or a self-priming surface pump for enhanced performance.

The control unit operates at a standard voltage of 230 V and supports a maximum current of 10 A, suitable for motors up to 1.3 kW. The maximum allowable pressure is 10 bar, ensuring safe operation in most domestic water systems. The working fluid temperature should not exceed 55°C to avoid damage to internal components. The inlet and outlet connections are both 1 inch threaded (G 1") for secure and leak-free installation. These specifications are essential for correct sizing and selection, particularly when matching the unit to the pump’s power and flow characteristics.

Installation and connection

To install the PC-16 control unit, locate it between the pump and the first point of water withdrawal. Ensure the unit is mounted in a stable, dry location to avoid exposure to moisture. Connect the inlet and outlet using 1 inch threaded fittings (G 1"). The electrical connection requires a 230 V supply and a dedicated socket for the pump. Verify that all electrical connections are properly insulated and grounded. Before commissioning, check that all joints are sealed and that the pressure gauge indicates normal readings. Common installation errors include improper sealing of pipe connections, incorrect electrical wiring, and failure to install a filter if the water contains impurities. These issues can lead to leaks, electrical faults, or premature wear of the pump and control unit.

Compatibility and accessories

The IBO PC-16 is compatible with a wide range of submersible and self-priming pumps used in domestic water systems. It integrates seamlessly with domestic water stations equipped with pressure tanks or self-priming surface pumps, enhancing system automation. For optimal performance, it is recommended to use the unit with clean water free of debris. In cases where the water contains particulates or sediments, an additional filter should be installed upstream of the control unit to prevent clogging. No specific accessories are required for basic operation, but filters and pressure-reducing valves may be necessary depending on the system configuration.

Technical background for designers

The PC-16 control unit operates based on pressure and flow monitoring. When the pump starts, the unit allows it to run for approximately 15 seconds to establish flow. If the pressure drops—such as when a valve is opened—the unit restarts the pump to maintain system pressure. In the event of dry running, the unit immediately stops the pump to prevent damage. This is achieved through internal sensors that detect the absence of water flow. The unit is constructed with durable materials capable of withstanding the operating conditions of domestic water systems. The integration of the pressure gauge provides real-time feedback on system performance, aiding in troubleshooting and maintenance. The unit’s efficiency and service life depend on factors such as water quality, proper installation, and regular inspection of seals and electrical connections.

Service and operation

Routine maintenance for the PC-16 involves checking the integrity of pipe connections and verifying the pressure gauge readings. Ensure that the electrical supply remains stable and that the pump socket is functioning correctly. If the system frequently experiences dry runs, inspect the water source for potential issues such as low water levels or blockages. While the unit does not require scheduled service intervals, periodic inspections are recommended to ensure continued reliable operation. Any signs of corrosion, leaks, or erratic pressure readings should be addressed promptly to avoid system downtime or component failure.

Frequently asked questions

Can the PC-16 be used with a self-priming surface pump?
Yes, the unit is compatible with self-priming (surface) pumps and can be integrated into systems using these types of pumps for water abstraction.

Does the unit require a pressure tank for operation?
No, the PC-16 eliminates the need for a separate pressure tank or pressure switch by combining these functions within the unit itself.

Can the unit handle water temperatures above 55°C?
No, the operating temperature of the fluid should not exceed 55°C. Exceeding this limit may cause damage to internal components.

Is a filter necessary when using the PC-16?
If the water contains impurities or sediments, a filter should be installed upstream of the unit to prevent clogging and ensure long-term reliability.
