Domestic waterworks JSW 100 / 50l

Product detailed description

Residential water supply systems often require compact, reliable pumps to maintain consistent pressure and flow. This domestic waterworks unit is commonly used in single-family homes, small apartment blocks and similar buildings. Installers typically encounter it in applications where the municipal water supply is insufficient or where a secondary water source is required. The unit can be integrated into systems such as water tanks, boreholes or well pumps, ensuring stable water delivery to taps, showers and appliances.

When installing this pump, the technician must ensure proper electrical and hydraulic connections. The unit is designed for indoor use and should be placed in a dry, accessible location for maintenance. It is important to verify that the pump is compatible with the existing piping and that all connections are secure and leak-free. The compact dimensions allow it to fit in standard utility rooms or dedicated pump chambers.

Technical parameters

The maximum flow rate of 75 l/min and a head of 45 m indicate that this pump is suitable for homes with moderate water demand. The 230 V power supply is standard for single-phase electrical systems in residential settings. The 1 m cable length requires careful routing during installation to avoid strain or damage. The dimensions (77x71x41 cm) determine the minimum space required for mounting and access. These parameters are essential for determining whether the pump meets the hydraulic and electrical requirements of the intended application.

Installation and connection

Installation begins with verifying the electrical supply matches the pump’s 230 V requirement. The 1 m power cable should be routed to a suitable junction box or control panel. For hydraulic connections, the pump must be connected to the water source and distribution system using appropriate pipe fittings. Thread types and diameters must match the inlet and outlet specifications of the pump and the system. A non-return valve should be installed upstream to prevent backflow, and a pressure gauge downstream to monitor system performance.

Common installation mistakes include improper grounding, incorrect pipe alignment and failure to secure the pump base. To avoid these issues, the pump should be mounted on a stable, vibration-dampened surface. The inlet and outlet pipes must be aligned to reduce stress on the pump body. After installation, the system should be tested for leaks and pressure stability before commissioning.

Compatibility and accessories

This pump is compatible with standard domestic water supply systems and can be used with various types of water sources, including tanks and wells. It requires a dedicated electrical circuit with appropriate protection devices, such as a circuit breaker or fuse. Additional accessories that may be needed include pipe fittings, valves, pressure switches and control panels. These components are not included in the standard package and must be ordered separately.

Technical background for designers

The pump operates on a centrifugal principle, using an impeller to generate flow and pressure. The motor is enclosed in a housing to protect against moisture and dust. The materials used are selected for their resistance to corrosion and wear, ensuring long-term reliability. The pump can be integrated into a broader water supply system with pressure switches or timers for automated control. The service life and efficiency depend on factors such as water quality, operating conditions and regular maintenance.

Proper sizing is critical to avoid overloading the pump or underperforming in the system. The flow rate and head must be matched to the building’s water demand and the height of the distribution points. Designers should also consider the pump’s electrical requirements and ensure that the system includes adequate protection against voltage fluctuations and overloads.

Service and operation

Regular inspection of the pump’s electrical connections and hydraulic seals is recommended to ensure continued performance. Any signs of leakage or unusual noise should be investigated immediately. The pump does not require scheduled maintenance intervals, but it should be checked periodically for wear and tear. If the system experiences reduced flow or pressure, the pump should be inspected for blockages or mechanical issues.

Frequently asked questions

Can the pump be connected to a pressure tank?
Yes, the pump can be connected to a pressure tank to provide stable water pressure and reduce cycling. A pressure switch may be required for automatic operation.

What is the recommended pipe size for the inlet and outlet?
The inlet and outlet sizes should match the pump’s specifications to ensure proper flow and prevent pressure loss. Consult the manufacturer’s documentation for exact dimensions.

Is the pump suitable for continuous operation?
The pump is designed for intermittent operation in typical residential applications. Continuous operation should be evaluated based on the system load and the pump’s thermal protection features.

Can the pump be installed vertically?
While the pump is typically installed horizontally, vertical installation is possible if the base is properly supported and the inlet and outlet are aligned correctly.
