S4 12/24 T 4GG 4" submersible pump for boreholes and wells - 4,0kW - 3x400V DAB.S4 GG

Product detailed description

This submersible pump is specifically engineered for installation in wells and boreholes with diameters exceeding 4 inches. It is suitable for various water supply and pumping tasks, including pressure boosting, water delivery to small and large facilities, irrigation, cleaning, and fire protection systems. The pump is constructed with corrosion-resistant materials such as stainless steel and technopolymer components to ensure durability and reliability in demanding environments. Its compact design allows for vertical installation and can also accommodate horizontal mounting when necessary. The pump’s high-efficiency impellers comply with the Eco Design Directive 2009/125/ES, making it a sustainable choice for modern water management systems.

The motor and housing are fully submerged during operation, allowing for direct immersion into water sources. This design minimizes wear and ensures smooth operation under continuous load. The pump features a built-in backflow prevention mechanism, either made from technopolymer or stainless steel, depending on the model. The stainless steel components used throughout the pump—such as the suction body, discharge body, and stainless steel AISI 304 parts—enhance structural integrity and resistance to chemical exposure. The pump is capable of handling non-aggressive, chemically neutral liquids with properties similar to water and can tolerate up to 150 grams of sand per cubic meter of water.

Technical parameters

The technical parameters listed provide essential information for correctly sizing and selecting the pump. For instance, the flow rate and head capacity determine the suitability for specific hydraulic demands. The impeller material and construction details help assess the pump’s performance in abrasive conditions. The motor specifications, including voltage and insulation class, guide compatibility with existing electrical systems and safety standards.

Installation and connection

For proper installation, the pump should be suspended vertically within the well using the provided hanger rings. Horizontal installation is possible but not recommended unless the pump is equipped with a cooling jacket to prevent overheating. The pump connects via standard thread types, and the user must verify the correct inlet and outlet dimensions for the specific model variant. The discharge port size varies between models, with smaller variants having 1¼ inch ports and larger models featuring 2 inch ports.

During installation, ensure that the pump is fully submerged and that the cable cover is intact to prevent mechanical damage. The maximum allowable depth for this model is 300 meters, and the pump should not exceed 20 starts per hour to avoid excessive wear on internal components. Check that the motor insulation class (F) and IP rating (IP68) match the site conditions. Common installation errors include incorrect orientation, failure to secure the cable properly, and neglecting to install a cooling jacket in non-vertical setups.

Compatibility and accessories

The IVAR S4 12/24 T 4GG 4 inch submersible pump is compatible with standard well and borehole systems that support 3x400V three-phase power supplies. Additional components such as a cooling jacket may be required for non-vertical installations. Although no alternative products are listed, the pump is typically integrated with control systems and filtration units depending on the application. Designers should consider the need for supplementary equipment like pressure switches, float switches, or remote monitoring systems based on the operational requirements of the site.

Technical background for designers

The IVAR S4 12/24 T 4GG operates on a centrifugal principle, where the impeller creates a pressure differential to move water through the system. The motor is a two-pole asynchronous type, with all parts in contact with water fabricated from stainless steel AISI 304. The bearings are grease-lubricated and cooled by a mixture of water and glycol, which helps maintain stable operating temperatures. The impeller material—technopolymer—is selected for its balance of strength, low weight, and resistance to chemical degradation. The motor’s housing is sealed to IP68 standards, ensuring complete protection against water ingress during submersion.

The integration of this pump into a system depends on factors such as the depth of the well, the required flow rate, and the presence of particulate matter in the water. The pump’s efficiency is influenced by the condition of the impeller and the alignment of the motor. Regular inspection of the sealing rings and bearings is necessary to maintain long-term performance. The pump’s insulation class F ensures that it can operate reliably in environments with elevated temperatures due to the thermal properties of the motor winding materials.

Service and operation

Maintenance of the IVAR S4 12/24 T 4GG involves periodic checks of the impeller and bearings for signs of wear or blockage. Ensure the intake screen remains free from debris to prevent clogging and reduce strain on the motor. The pump should be inspected after extended periods of inactivity to confirm that all seals remain intact and that the motor is not compromised by condensation or corrosion. While no specific service intervals are provided, regular monitoring of performance indicators such as flow rate and power consumption can help identify potential issues early.

Key checkpoints during operation include verifying the motor’s temperature, confirming the absence of abnormal vibration, and checking for any changes in the pump’s noise level. These observations can indicate mechanical or electrical faults. If the pump shows a decline in performance or fails to start, disconnection from the power supply and a visual inspection are recommended before attempting further troubleshooting. In cases of suspected internal damage, the unit should be removed from the well for detailed examination and repair.

Frequently asked questions

Can the IVAR S4 12/24 T 4GG be mounted horizontally?
Yes, the pump can be installed horizontally, though it is recommended to fit a cooling jacket to prevent overheating and maintain motor efficiency.

What is the maximum depth for this pump?
The pump is designed for maximum submersion depths of 300 meters, making it suitable for deep wells and boreholes.

Is the pump suitable for water with sand content?
It can handle up to 150 grams of sand per cubic meter of water, but it is intended for clean, non-abrasive fluids primarily.

What is the recommended power supply for the IVAR S4 12/24 T 4GG?
The pump requires a three-phase power supply of 3x400V at 50 Hz for optimal performance and stability.
