More about this product
Non-self-priming, single-stage, centrifugal pump designed for handling wastewater, process water and unscreened raw sewage. The pump is designed for intermittent and continous operations in submerged installation. The revolutionary S-tube® impeller provides free spherical passage of solids up to 1 15/16 in and is suitable for wastewater with a dry matter content of up to 3 %. A unique stainless-steel clamp assembling system enables quick and easy disassembly of the pump from the motor unit for service and inspection. No special tools are required. Pipework connection is via a DIN flange.
All pumps have the following features:
- Watertight cable entry of corrosion-resistant polyamide
- Power supply cable incorporating wires for thermal sensors in the motor windings
- No additional cable required for sensors in pumps with sensors
- Monitoring of operating conditions for pumps with sensors
- Moisture detector for continuous monitoring of motor enclosure and automatic cut-out in case of leakage
- Heavy-duty bearings greased for life
- Built for frequency converter operation
- Smooth pump surface prevents dirt and impurities from sticking to the pump
- Self-cleaning channel impeller with long vanes reducing the risk of jamming or clogging, or Super-Vortex impeller with high pumping efficiency and less downtime
- Explosion-proof motors for potentially explosive environments
- Motor insulation class F (155 °C)
- Enclosure class IP68 with thermal sensor in each phase

What is a submersible pump?
A submersible pump is designed to operate fully submerged in the liquid it is moving. The motor is sealed inside the pump body and cooled by the surrounding water. Submersibles are used for drainage, sewage, septic tanks, deep wells and boreholes, and for raising water from sumps, cellars and floodwater. Many stocked at Anglian Pumping handle solids in suspension.
Can submersible pumps handle solids and sewage?
Yes – some submersibles are designed for clean water only, others handle solids up to 50 mm or full raw sewage. Anglian Pumping stocks ABS, BBC, Flygt and T-T Submersibles ranges that include vortex, single channel and grinder impellers for different solids handling requirements. Always match the pump to the maximum solid size and the type of effluent it will see.
When should I use a submersible pump instead of a surface pump?
Use a submersible when the water level is more than around 8 metres below the pump installation point – surface pumps cannot self-prime beyond that depth. Submersibles are also better when the liquid contains solids, when noise must be minimised, or when the pump needs to operate in confined spaces such as sumps and chambers where a surface pump would not fit.
