WQ 150-7.5 - submersible sewage pump
The IBO WQ 150-7.5 submersible pump is an industrial unit with a channel impeller offering a passage of up to 75 mm, designed to pump raw sewage containing fecal matter, greywater, and rainwater. Its large passage allows it to pump media containing suspended solids and solid particles with ease.
Who it's for
-
Municipal utilities and wastewater treatment plants – the large impeller passage (75 mm) allows raw sewage containing fecal matter and suspended solids to be pumped without risk of clogging.
-
Companies carrying out large industrial installations – its high efficiency relative to motor power makes it suitable for pumping large volumes of process water.
-
Companies installing permanent pumping stations – the cast iron base allows installation on a coupling foot or as a freestanding unit in a tank.
-
Pond and retention tank managers – the pump is suitable for draining large bodies of water.
Applications
The WQ 150-7.5 submersible pump is designed to pump raw sewage containing fecal matter, greywater, and rainwater. It is suitable for draining and pumping large volumes of liquid, for example from ponds or lakes.
With a channel impeller passage of up to 75 mm, the pump can handle media containing suspended solids and solid particles. The unit can be installed on a coupling foot or freestanding in a tank, thanks to its cast iron base and DN150 PN6 connection flange.
Features of the WQ 150-7.5 pump
The pump features a grey cast iron motor housing and pump housing. The impeller is made of ductile 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 speed than typical two-pole submersible pumps, resulting in high efficiency relative to motor power. The double mechanical seal in a SiC/SiC arrangement, additionally protected by an oil chamber, ensures quiet operation and a long service life. The built-in thermal protection protects the motor from overheating.

Frequently asked questions (FAQ) – WQ 150-7.5 submersible pump
What types of wastewater is the WQ 150-7.5 pump designed for?
The pump is designed for raw sewage containing fecal matter, greywater, and rainwater. The passage through the channel impeller is 75 mm, allowing it to handle fluids containing suspended matter and solid particles.
Why does the WQ 150-7.5 pump have a four-pole motor?
The four-pole motor runs at a lower rotational speed (1450 rpm) than typical two-pole submersible pumps, resulting in high efficiency 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 connection flange, the pump can be installed on a coupling foot in a fixed installation or placed free-standing directly in the tank.
Does the WQ 150-7.5 pump require additional control equipment?
Yes, the pump is powered by a 400 V three-phase supply and does not have a built-in switch, so it must be connected to an external control panel with motor protection.
Where can you buy the WQ 150-7.5 submersible pump?
Dambat does not sell directly. The WQ 150-7.5 pump is available from trade partners, plumbing wholesalers, and authorized online distributors.
What are the warranty terms for the WQ 150-7.5 pump?
IBO – 24 months (2 years) manufacturer's warranty. Dambat provides warranty and post-warranty service.
