Domestic waterworks with submersible pump 3Ti-27 with frequency converter - RTS

Product detailed description

Domestic water systems with submersible pumps are commonly used in residential properties, cottages, and small commercial buildings to provide a reliable water supply from wells, boreholes, or storage tanks. These systems are particularly useful in areas where mains water supply is unavailable or insufficient. The 3Ti-27 pump is designed for continuous operation and can be integrated into automatic pressure stations or irrigation systems. Installers typically deal with system setup, pressure regulation, and ensuring compatibility with existing plumbing infrastructure. The system is suitable for both new and existing installations, including deep wells and narrow boreholes.

When installing this system, it is important to consider the water source characteristics, such as depth, diameter, and water quality. The system is also suitable for use in agricultural or horticultural applications where water needs to be pumped from storage tanks or reservoirs. The frequency converter allows for smooth motor operation and helps maintain a stable pressure in the system, reducing mechanical stress and extending the pump's service life.

Technical parameters

The maximum flow rate of 50 l/min and a head of 110 m indicate the system's ability to deliver water over long distances or to higher elevations. The 230 V supply voltage is standard for single-phase systems, and the 20 m cable length allows for flexible installation in various well or tank configurations. The dimensions of 142 x 7.4 cm are important for ensuring the pump fits within the installation space.

Installation and connection

Installation begins with positioning the submersible pump at the required depth in the water source. The pump is connected to the frequency converter using the 20 m supply cable. The system includes a pressure tank, check valve, and fittings for a 1-inch connection. It is essential to ensure that the pump is fully submerged and that the cable is routed safely to avoid damage. Common installation mistakes include incorrect cable routing, improper pump positioning, and failure to secure the system components correctly. The pump should be tested for dry-running protection and low-level shutdown to prevent damage in case of water level fluctuations.

Compatibility and accessories

This system is compatible with standard domestic water supply systems and can be integrated with automatic pressure stations or irrigation controllers. The included pressure tank, check valve, and fittings are essential for proper operation. Additional components such as filters or expansion vessels may be required depending on the water source and system requirements. The system is suitable for use in both residential and commercial applications and can be adapted for continuous operation in industrial settings.

Technical background for designers

The 3Ti-27 submersible pump operates on a single-phase motor with a built-in thermal protection system. The hydraulic section is separated from the motor, allowing for easier maintenance and repair. The pump is constructed from stainless steel, providing resistance to corrosion and extending its service life. The frequency converter allows for variable speed operation, which helps maintain a stable pressure in the system and reduces energy consumption. The pump is designed to handle abrasive materials such as sand, making it suitable for use in wells or boreholes with poor water quality. The system's modular design allows for easy integration into existing water supply systems and ensures long-term reliability.

Service and operation

Regular maintenance is essential to ensure the system operates efficiently. This includes checking the pump's operation, inspecting the cable for damage, and verifying the pressure tank's functionality. The thermal protection system helps prevent overheating, and the dry-running protection ensures the pump shuts down if the water level drops too low. The system should be inspected periodically for signs of wear or damage, particularly in the hydraulic section and motor housing. No specific service intervals are provided in the technical data, but routine checks are recommended to maintain system performance.

Frequently asked questions
