Submersible sludge pump IBO WQF 250

Product detailed description

Submersible sludge pumps are essential in applications where water is contaminated with suspended solids, sludge or other non-abrasive particulates. The IBO WQF 250 is commonly used in basement water removal, surface water extraction from rivers, ponds and swimming pools, and in industrial or municipal settings where contaminated water needs to be transferred. It is designed for installation in non-aggressive liquids with a maximum temperature of 35 °C and ambient temperature up to 70 °C. The pump is not suitable for use with water containing sand or abrasive materials, as these can damage internal components and reduce service life.

Installers and technicians working in civil engineering, building services or water management will find this pump suitable for temporary or semi-permanent installations where water levels fluctuate and solids are present. The compact dimensions and 5 m power cable length allow for flexible placement in confined spaces or remote locations. The pump’s robust construction ensures reliable operation in challenging environments, provided the installation follows technical guidelines and system compatibility is verified.

The IBO WQF 250 has a maximum flow rate of 170 l/min and a head of 8 m, making it suitable for applications requiring moderate pumping capacity. The 230 V supply voltage is compatible with standard single-phase electrical systems. The 5 m power cable length allows for placement in tanks or sumps without the need for additional cabling. The dimensions (39 x 17 cm) and weight (9 kg) indicate a compact and portable design suitable for manual handling and installation in tight spaces. These parameters are essential for sizing the pump to the system’s hydraulic requirements and ensuring compatibility with the power supply and installation environment.

Installation and connection

The IBO WQF 250 is installed directly into the liquid, fully submerged. The installation site must be free of sharp edges or obstructions that could damage the pump casing or impeller. The 5 m power cable should be routed to a suitable power supply, ensuring the connection is made in a dry and accessible location. The pump must be connected to a 230 V single-phase supply with appropriate circuit protection and a residual current device (RCD) for safety. The pump’s inlet and outlet ports must be connected to the system using compatible pipe fittings and seals to prevent leaks. Common installation mistakes include incorrect cable routing, failure to secure the pump in place, and neglecting to check the electrical connection for proper grounding and insulation. After installation, the pump should be tested for leaks and proper operation before being put into service.

Compatibility and accessories

The IBO WQF 250 is compatible with standard plumbing and drainage systems using non-abrasive fluids. It is typically connected to a discharge pipe with a diameter matching the pump’s outlet size. For installations requiring remote control or automation, the pump can be integrated with control panels or level switches to manage operation based on water levels. Additional accessories such as flexible couplings, check valves and strainers may be required to protect the pump from debris and ensure smooth flow. The pump is not compatible with systems handling sand or abrasive materials, as these can cause premature wear and failure.

Technical background for designers

The IBO WQF 250 operates using a centrifugal pump mechanism, where the impeller generates a pressure differential to move the liquid. The pump is constructed from durable materials suitable for handling contaminated water and sludge. The sealed motor and corrosion-resistant components ensure reliable operation in wet environments. The pump is designed to be integrated into systems where water levels vary and solids are present. The service life and efficiency of the pump depend on the quality of the installation, the condition of the liquid being pumped, and the frequency of maintenance. Proper system design should account for the pump’s flow and head capabilities, as well as the need for regular inspection and cleaning to prevent clogging and wear.

Service and operation

The IBO WQF 250 requires regular inspection to ensure continued performance and prevent blockages. The pump should be checked for leaks, unusual noise or vibration, and signs of wear on the impeller and seals. The power cable and electrical connections should be inspected for damage or insulation degradation. The pump should be removed periodically for cleaning to remove any accumulated sludge or debris that could affect performance. No specific service intervals are provided in the technical data, but routine checks are recommended based on the operating conditions and frequency of use. In case of malfunction, the pump should be disconnected from the power supply and inspected for internal damage or blockages before attempting repairs.

Frequently asked questions

Can the IBO WQF 250 be used for water with high solid content?
The pump is suitable for sludge and contaminated water but not for water containing sand or abrasive materials, as these can damage internal components.

Is the IBO WQF 250 compatible with a 230 V single-phase supply?
Yes, the pump is designed for 230 V operation and is compatible with standard single-phase electrical systems.

What is the maximum depth the IBO WQF 250 can be submerged?
The pump is designed for full submersion, but the maximum depth is not specified in the technical data. It should be installed in accordance with the manufacturer’s guidelines.

Can the IBO WQF 250 be used in a closed-loop system?
The pump is not designed for closed-loop systems and is intended for open-system applications such as water removal and surface water extraction.
