WQ 150-7.5 – submersible sewage pump
The IBO WQ 150-7.5 submersible pump is an industrial device with a channel impeller offering a clearance of up to 75 mm, designed for pumping raw sewage containing fecal matter, greywater, and rainwater. Thanks to its large clearance, it safely pumps media containing suspended solids and solid particles.
Who it is for
-
Municipal utilities and wastewater treatment plants – the large clearance through the impeller (75 mm) allows raw sewage containing fecal matter and suspended solids to be pumped without the risk of blockage.
-
Companies implementing large industrial installations – the high capacity relative to motor power is suitable for pumping large quantities of process water.
-
Installation companies building permanent pumping stations – the cast-iron base enables installation on a coupling foot or as a freestanding unit in a tank.
-
Managers of ponds and retention tanks – the pump is suitable for draining large water reservoirs.
Applications
The WQ 150-7.5 submersible pump is designed for pumping raw sewage containing fecal matter, greywater, and rainwater. It is suitable for draining and pumping large quantities of media, for example from ponds or lakes.
Thanks to the 75 mm clearance through the channel impeller, the pump tolerates media containing suspended solids and solid particles. The device can be installed on a coupling foot or as a freestanding unit in a tank, thanks to its cast-iron base and DN150 PN6 flanged connection.
Features of the WQ 150-7.5 pump
The pump features a motor housing and pump housing made of grey cast iron. The impeller is made of ductile cast iron, which is mechanically stronger and more resistant to cracking than standard grey cast iron, while the shaft is made of AISI 304 stainless steel.
The four-pole motor operates at a lower rotational speed than typical two-pole submersible pumps, resulting in high capacity relative to motor power. The double mechanical seal in a SiC/SiC configuration, additionally protected by an oil chamber, ensures quiet operation and a long service life. Thermal protection built into the motor prevents overheating.

Frequently asked questions (FAQ) – WQ 150-7.5 submersible pump
What type of sewage is the WQ 150-7.5 pump designed for?
The pump is designed for raw sewage containing fecal matter, greywater, and rainwater. The clearance through the channel impeller is 75 mm, allowing it to tolerate media containing suspended solids and solid particles.
Why does the WQ 150-7.5 pump have a four-pole motor?
The four-pole motor operates at a lower rotational speed (1450 rpm) than typical two-pole submersible pumps, resulting in high capacity relative to motor power and quieter operation.
How can the WQ 150-7.5 pump be installed?
Thanks to its cast-iron base and DN150 PN6 flanged connection, the pump can be installed on a coupling foot in a permanent installation or as a freestanding unit directly in a tank.
Does the WQ 150-7.5 pump require additional control equipment?
Yes. The pump is powered by 400 V three-phase electricity and does not have a built-in switch, so it must be connected to an external control cabinet with motor protection.
Where can the WQ 150-7.5 submersible pump be purchased?
Dambat does not sell directly. The WQ 150-7.5 pump is available from commercial partners, installation wholesalers, and authorized online distributors.
What warranty terms apply to the WQ 150-7.5 pump?
IBO – 24-month (2-year) manufacturer’s warranty. Warranty and post-warranty service is provided by Dambat.
