Sludge set - Submersible Sludge Pump WQF 750 with 20m hose

Product detailed description

Submersible sludge pumps are essential in construction and maintenance projects where water removal from contaminated or sludge-laden sources is required. Installers commonly use these units in flooded basements, surface water collection from rivers, ponds, and swimming pools, and in underground water extraction scenarios. The IBO WQF 750 is suited for environments where the pumped liquid contains suspended solids and organic matter but not sand or abrasive particles. It is particularly useful in temporary dewatering applications and for emergency water removal in industrial or residential settings.

The pump is designed for direct immersion in the liquid, ensuring efficient operation without the need for priming. It is typically deployed in sumps, trenches, or open water bodies where the water level fluctuates. The compact dimensions and robust construction make it suitable for tight spaces and harsh conditions. The 8 m power cable allows for flexible positioning within the tank or pit, and the 20m hose ensures sufficient reach for directing the discharge to a safe location.

The pump’s maximum flow rate of 400 l/min and a head of 12 m make it suitable for medium to large-scale dewatering tasks. The 230 V single-phase supply is standard for most European installations, and the 8 m power cable length allows for positioning the pump at a safe distance from the electrical source. The 46 x 24 cm dimensions and 18 kg weight ensure it is manageable for manual installation and removal. These parameters are critical for sizing the pump to the volume and elevation of the water being removed.

Installation and connection

The installation process begins with positioning the pump at the bottom of the sump or tank, ensuring it is fully submerged. The 8 m power cable should be routed to a suitable electrical socket with appropriate protection. The 20m hose is connected using the included coupling with external thread and the hose end fittings marked as type C. It is important to check that the hose is free of kinks and that all connections are secure to prevent leaks or disconnections during operation. A common mistake is failing to ensure the pump is fully submerged, which can lead to overheating or mechanical failure. Additionally, the pump must not be used in environments with sand or abrasive particles, as this can damage the impeller and reduce service life. The installation should also include a check for the presence of a ground fault circuit interrupter (GFCI) to ensure electrical safety, especially in wet environments.

Compatibility and accessories

The IBO WQF 750 is compatible with standard 230 V electrical systems and can be integrated into temporary dewatering setups or permanent installations where sludge and contaminated water are present. The 2-inch hose is suitable for connecting to standard discharge points or to a larger drainage system. The set includes a coupling with external thread, which allows for secure attachment to other components or fittings. No additional accessories are required for basic operation, but in larger systems, a control panel or timer may be added for automation.

Technical background for designers

The IBO WQF 750 operates on a centrifugal pumping principle, where the impeller generates a pressure differential to move the liquid. The motor is sealed and insulated to prevent water ingress, and the housing is constructed from durable materials to withstand exposure to sludge and organic matter. The pump is designed for intermittent operation and is not suited for continuous use in high-temperature environments. The maximum liquid temperature of 35 °C and ambient temperature of 70 °C are critical for ensuring the longevity of the motor and internal components.

Service and operation

Regular inspection of the pump and hose is recommended to ensure there are no blockages or wear. The pump should be removed periodically for visual inspection of the impeller and motor housing. If the pump is used in environments with high concentrations of suspended solids, more frequent checks may be necessary. No specific service intervals are provided in the technical data, but the pump should be replaced if signs of mechanical wear or electrical faults are observed. The hose should be cleaned after each use to prevent clogging and extend its service life.

Frequently asked questions

Can the IBO WQF 750 be used in water with a high organic content?
Yes, the pump is suitable for handling water with organic matter and sludge, provided it does not contain abrasive materials like sand.

Is the pump suitable for continuous operation?
No, the pump is designed for intermittent use and should not be operated continuously for extended periods.

What is the maximum depth at which the pump can be submerged?
There is no specified maximum depth, but the pump must remain fully submerged to function correctly and avoid damage.

Can the 20m hose be extended?
Yes, the hose can be extended using compatible fittings, but the pressure and flow rate may be affected depending on the additional length and elevation.
