Domestic waterworks with submersible pump 3" STM 24/140l stainless steel - RTS

Product detailed description

Domestic water supply systems with submersible pumps are commonly installed in residential properties, summer homes, schools, and agricultural facilities where a reliable water source is required. These systems are particularly suited for environments where water must be drawn from depths exceeding 8 m, such as in newly drilled wells or boreholes that may contain abrasive particles like sand. The system is designed to integrate into existing plumbing systems or new installations, providing a continuous and stable water supply for domestic use, irrigation, and other utility purposes. Installers typically handle tasks such as pump placement, pressure tank setup, and connection to the distribution network, ensuring the system operates efficiently and reliably.

When installing this system, it is important to consider the hydraulic characteristics of the water source, including the depth, water quality, and potential presence of abrasive materials. The submersible pump must be lowered into the well or borehole with care to avoid damage, and the pressure tank must be positioned at a suitable height to ensure proper system function. The system is typically connected to the building's plumbing via standard pipe fittings and valves, with the pressure switch controlling pump activation based on demand.

Technical parameters

The technical parameters of this system are essential for proper sizing and selection. The 230 V motor ensures compatibility with standard electrical systems, while the 93 m head capacity allows for water extraction from significant depths. The 100 l/min maximum flow rate indicates the system's ability to supply water to multiple fixtures simultaneously. The 20 m power cable length provides flexibility in pump placement, and the 116 x 7.5 cm dimensions of the system must be considered for storage and installation space.

Installation and connection

Installation of the domestic water supply system with a submersible pump involves several key steps. First, the pump must be lowered into the well or borehole, ensuring it is fully submerged and free from obstructions. The pressure tank should be mounted in a stable location, and the pressure switch must be connected to the tank and pump to regulate operation. The system includes a check valve to prevent backflow and a pressure relief valve to protect against overpressure. Common connection sizes include 1 inch and 5/4 inch fittings, with the system requiring a 230 V electrical supply. Installers should verify the integrity of all connections, check for leaks, and ensure the pump is properly grounded to prevent electrical hazards.

Compatibility and accessories

This system is compatible with standard plumbing systems and can be integrated into both new and existing water supply networks. The included accessories, such as the pressure tank, pressure switch, check valve, and fittings, are essential for system operation. Additional components that may be required include a pressure gauge, expansion vessel, and electrical protection devices. Installers should ensure that all components are compatible with the system's specifications and that any additional accessories are sourced from reputable suppliers to maintain system reliability.

Technical background for designers

The submersible pump operates on the principle of centrifugal force, using an impeller to draw water from the source and discharge it through the system. The stainless steel construction of the pump and pressure tank provides resistance to corrosion and ensures long-term durability, particularly in environments with abrasive water. The floating impeller design reduces wear from sand and other particulates, enhancing the pump's service life. The system is designed to integrate into a closed-loop water supply network, with the pressure tank acting as a buffer to maintain consistent pressure and reduce pump cycling. Factors that affect system efficiency include water quality, pump placement depth, and the condition of the electrical supply.

Service and operation

Regular maintenance is essential to ensure the system operates efficiently and reliably. Installers should periodically inspect the pump and pressure tank for signs of wear, corrosion, or damage. The pressure switch should be tested to ensure it activates and deactivates the pump correctly, and the pressure tank should be checked for proper inflation. The check valve must be verified to prevent backflow, and all connections should be inspected for leaks. If the system experiences reduced performance or unusual noise, the pump should be removed for inspection and cleaning. No specific service intervals are provided in the brief, but routine checks are recommended to maintain system function.

Frequently asked questions

Can the pump be used in newly drilled wells with high sand content?
Yes, the floating impeller design allows the pump to handle water with elevated sand content, making it suitable for use in newly drilled wells.

What is the maximum depth from which the pump can extract water?
The pump is capable of extracting water from depths up to 93 m, making it suitable for deep well applications.

Is the pressure tank compatible with other water supply systems?
The 140 L stainless steel pressure tank is designed to integrate with standard water supply systems and can be used in both residential and agricultural installations.

What electrical requirements are needed for the system?
The system requires a 230 V electrical supply, and the pump must be properly grounded to ensure safe operation.
