Domestic waterworks with submersible pump 3Ti-27 / 80l - RTS

Product detailed description

This submersible pump system is designed for domestic water supply applications in residential properties, cottages, schools and agricultural facilities. It provides a complete solution for drawing potable and utility water from wells or boreholes with depths exceeding 8 m. The system includes all essential components for immediate installation and is particularly suited for new or recently drilled wells that may contain abrasive particles such as sand. The floating impeller design minimises wear from particulate matter, ensuring long-term reliability in challenging water conditions.

The system is commonly used in low-pressure gravity-fed well systems and can be integrated with standard domestic plumbing networks. Installers typically encounter this unit in rural water supply projects, off-grid developments and seasonal properties with limited access to municipal water. The compact pressure tank and built-in controls simplify system setup and reduce the need for additional components in most standard installations.

The maximum flow rate of 50 l/min and head of 110 m make this unit suitable for single-family homes with moderate water demand. The 230 V rating requires standard household electrical infrastructure. The 20 m cable length allows flexibility in pump placement within the well. The pressure tank capacity of 80 l ensures stable water delivery during variable demand periods. The sand resistance feature is critical for wells with high particulate content, reducing the risk of mechanical failure due to abrasion.

Installation and connection

Begin by securing the submersible pump to the well casing using the provided suspension kit. Ensure the pump is fully submerged and the intake screen is clear of obstructions. Connect the pressure tank via the 1" inlet using the supplied coupling and check for proper alignment. The 32x1" adapters allow flexible orientation depending on tank position. Mount the pressure switch according to the manufacturer's recommended height relative to the pump to ensure accurate pressure readings. Verify all threaded connections (both internal and external 32x1") are sealed with appropriate pipe thread sealant. The 80 cm connecting hose should be routed without kinks between the pump and tank. Install the check valve upstream of the tank to prevent backflow when the pump is inactive. Confirm the 20 m power cable is routed safely away from moving parts and secured against accidental disconnection. Test the system under load to verify stable pressure and flow before finalising the installation.

Compatibility and accessories

This system is compatible with standard 230 V electrical supplies and conventional domestic plumbing systems using 1" piping. The included components cover basic installation requirements, but additional valves, filters or expansion tanks may be needed for larger or more complex systems. Installers should ensure all fittings and piping are rated for the maximum working pressure of 110 m head. No additional related products are required for standard applications.

Technical background for designers

The submersible pump operates on centrifugal force generated by the floating impeller assembly, which adjusts to varying particulate loads in the water. Constructed with abrasion-resistant materials, the pump housing and internal components are designed to withstand prolonged exposure to sand-laden water. The 80 l pressure tank functions as both a buffer and a stabiliser, reducing pump cycling and maintaining consistent pressure throughout the distribution network. The overall system efficiency depends on proper well depth, water quality and correct positioning of the pressure switch relative to the tank and pump.

Service and operation

Regular inspection of the intake screen and pump housing is recommended to remove accumulated particulate matter. Check the pressure tank's air chamber periodically using a manometer to ensure optimal performance. The check valve and isolation ball valve should be tested annually for leaks or blockages. No specific service intervals are provided in the technical documentation, but routine maintenance will extend the system's operational life. Any abnormal noise or vibration during operation indicates potential wear and requires investigation.

Frequently asked questions

Can the pump handle water with high sand content?
Yes, the floating impeller design increases resistance to abrasion from particulates such as sand in the water supply.

Is the pressure tank fixed in orientation?
No, the tank is designed to operate in either upright or horizontal positions, eliminating the need for additional mounting brackets.

What is the recommended minimum well depth for this pump?
The system is suitable for wells deeper than 8 m, where standard surface pumps would struggle to maintain consistent flow.

Does the system include all necessary control components?
Yes, the pressure switch, check valve and isolation valve are all included in the standard package for immediate installation.
