Submersible sludge, drainage pump 80 KBFU - 5,5 400V

Product detailed description

This submersible sludge pump is commonly deployed in construction and civil engineering projects where dewatering of excavations is required. Installers typically use it in open pits, foundation trenches and temporary water accumulation zones during earthworks. The pump is designed for operation in environments where water contains suspended solids such as sand, silt or fine debris. Its ability to function even when partially submerged makes it suitable for fluctuating water levels, such as those encountered in open excavation sites.

The pump is typically installed directly into the water body using a rigid mounting frame or a flexible support system. It is connected via a three-phase power supply and requires a dedicated circuit breaker. The installation must account for cable routing and access for maintenance. The pump’s robust construction ensures it can withstand harsh conditions often found in construction environments.

Technical parameters

The 10 m cable length allows sufficient reach for most excavation sites without requiring additional extensions. The 1300 l/min flow rate is suitable for large-volume dewatering tasks, while the 34 m head ensures the pump can lift water over significant vertical distances. These parameters are critical for determining the suitability of the pump for specific applications, especially when planning the layout of dewatering systems.

Installation and connection

Installation begins with positioning the pump in the water body using a support frame or rope system. The pump should be placed at a depth that avoids air intake, which could lead to cavitation or reduced efficiency. The 10 m power cable must be secured and routed to a safe location, avoiding sharp edges or abrasive surfaces. Connect the pump to a 400 V three-phase supply via a certified industrial socket and a circuit breaker with appropriate overload protection.

Common installation errors include insufficient submersion, which can lead to overheating, and incorrect electrical connections, such as reversed phase rotation. To avoid these issues, verify the pump’s orientation and ensure all electrical connections are tightened according to the manufacturer’s specifications. A final check of the pump’s operation under load is recommended before leaving the site unattended.

Compatibility and accessories

This pump is compatible with standard industrial power supplies and can be integrated into dewatering systems with control panels or automated level sensors. Accessories such as a mounting frame, extension cables or a control box may be required depending on the installation setup. No specific related products are mentioned in the brief.

Technical background for designers

The IBO 80 KBFU 5 5 400V operates on a centrifugal pump mechanism, where an impeller creates a pressure differential to move water through the system. The pump is constructed with a heavy-duty housing that provides mechanical stability and heat dissipation, even in partially submerged conditions. The cooling jacket design prevents overheating by allowing water to circulate around the motor, ensuring continuous operation in challenging environments.

Designers should consider the pump’s flow rate and head when calculating the hydraulic requirements of the dewatering system. The pump’s performance is influenced by the viscosity and particle content of the water being pumped. To maximise service life, the pump should be used in accordance with the manufacturer’s guidelines for media composition and operating conditions.

Service and operation

Regular inspection of the pump’s intake screen is recommended to prevent blockages from large debris. The motor and internal components should remain submerged during operation to avoid damage. No specific service intervals are provided in the brief; however, routine checks for wear, vibration and noise levels are advisable. In case of unusual operation, the pump should be removed from the water and inspected for signs of mechanical or electrical failure.
