Submersible Sewage Pump — Anti-Clog Cutter & Wastewater Duty
A submersible sewage pump (SWQ) moves raw sewage, mixed and mud water in municipal and industrial wastewater duty, with impellers designed to resist clogging.

Municipal and industrial sewage carries rag, fibre and stringy material that wraps around an impeller vane and builds until the passage closes. Grit is a wear problem; fibre is a blockage problem, and they call for different impellers. The SWQ range answers this with channel impellers in single-vane, twin-vane and three-vane forms, plus a cutter impeller option where the incoming flow is fibrous enough that any passage will eventually rag up.
Model Performance Data
Clear-water performance for representative frames across the range; three duty points are shown per model. Outlet sizes run from 50 to 600 mm. Other frames are available — send your duty point and we will issue the matching curve.

Choosing the Impeller
A single-vane channel impeller gives the largest clear passage and suits the raggiest flows, at some cost in hydraulic smoothness. Twin-vane and three-vane forms run more smoothly and hold efficiency better where the medium is closer to dirty water than to raw sewage. The cutter option shears fibre at the inlet instead of trying to pass it, which is the right answer for pump stations that have been hand-cleared more than once. Flow reaches 4,000 cubic metres per hour, and the maximum solid size is limited to 50 % of the pump outlet diameter.
Motor and Sealing
Motors are rated IPX8 with class F insulation to 155 degrees Celsius. Shaft sealing uses two mechanical seals in series: tungsten carbide against tungsten carbide on the pump side, graphite against silicon carbide on the motor side, running on SKF or NTN bearings. Head and power coverage is provided on request against your duty point.
Series and Duty
The submersible sewage pump serves municipal works, industrial buildings, hotels, hospitals, civil-defence installations and mines. It handles sewage, waste water, rainwater and municipal service water carrying solid grains and long fibrous matter.
Where It Is Used
Typical service is raw sewage, mixed water, sludge and general drainage at municipal treatment works and at industrial effluent plants. Tell us the fibre content, the solids grading, whether the sump can be isolated for maintenance and the head against which the pump must deliver, and we will confirm the impeller form and frame size.

|---|---|
| Outlet diameter | 50 to 600 mm |
| Medium temperature | Not above 40 °C |
| Medium density | Not above 1200 kg/m³ |
| pH range | 5 to 9 |
| Maximum solid size | Not more than 50 % of the pump outlet diameter |
| Power supply | 380 V, 50 Hz. The motor runs correctly only where voltage and frequency deviation stays within 5 % |
| Bearings | Imported SKF or NTN bearings |
| Cooling | Built-in cooling system: part of the pumped liquid circulates between the cooling jacket and the casing to carry away motor heat, so the pump runs whether the motor is above or below the liquid level. Where external cooling is required, the jacket can be isolated from the casing and connected to a separate cooling system |
| Rotation | Counter-clockwise viewed from the suction |
| Minimum liquid level | The pump must not run below the lowest liquid level marked on the installation drawing |

Will the impeller clog on fibrous municipal sewage? Do you offer channel or cutter impellers?
The SWQ range offers single-vane, twin-vane and three-vane channel impellers selected according to the medium, with a cutter impeller option for fibrous sewage. Flow reaches 4,000 m³/h, and the maximum solid size is limited to 50 % of the pump outlet diameter. Motors are IPX8 with F-class insulation rated to 155 °C, using German Bogman mechanical seals — tungsten carbide against tungsten carbide on the pump side, graphite against silicon carbide on the motor side — and SKF or NTN bearings. Typical service covers raw sewage, mixed water, sludge and drainage at municipal and industrial treatment plants. Head and power coverage is provided on request against your duty point.
