WQ-80-3.0 - 400 V submersible sewage pump
The IBO WQ-80-3.0 submersible pump with a dual-channel closed impeller
is a 400 V three-phase device designed for industrial applications. It is ideal for pumping
light, pretreated sewage, dirty water, and rainwater. The double, independent
sealing system and oil chamber protect the motor from water, even
if one of the seals is damaged.
Who it's for
-
Industrial plants and wastewater treatment plants – the double sealing system and oil chamber protect the motor even if one of the seals is damaged.
-
Sewage pumping stations and permanent installations – the option of mounting on guide rails with a foot coupling makes it easier to replace the pump without emptying the tank.
-
Companies carrying out large-scale installations – the 400 V three-phase power supply makes integration with distribution boards and control cabinets easier.
-
High-duty facilities – the reinforced shaft construction withstands impacts from hard objects without reducing service life.
Applications
The WQ-80-3.0 submersible pump with a dual-channel closed impeller is designed
for pumping light, pretreated sewage, dirty water, and rainwater. The pump is suitable for domestic wastewater, including greywater and blackwater,
containing solid particles and short fibrous materials, originating, among other sources,
from residential and utility buildings and wastewater treatment plants.
The device operates vertically, with a maximum pumped liquid temperature
of 40°C and water pH in the range of 6–10—wider than in typical sewage pumps, allowing it to handle both mildly acidic and alkaline wastewater without accelerated corrosion of cast-iron components. The motor winding's Class F insulation provides a greater thermal margin than the popular Class B, which is important for continuous operation at elevated liquid temperatures.
Features of the WQ-80-3.0 pump
The pump features a cast iron construction – the motor housing, body, and impeller are made of cast iron,
providing a rigid housing and effectively damping vibrations during high-capacity operation.
The shaft is made of AISI 304 stainless steel, so it does not corrode in constant contact
with wastewater and maintains precise impeller alignment throughout its service life.
The short shaft support and rigid bearing arrangement further reduce vibration, allowing the
shaft to withstand high shock loads even during occasional contact with hard
objects.
The impeller-side seal uses a silicon carbide/silicon carbide arrangement –
a hard material pairing with high abrasion resistance and a low coefficient of
friction, extending the seal's service life during constant contact with contaminated water.
The independent second seal on the motor side operates immersed in an oil chamber,
using a carbon/ceramic arrangement, cooled and lubricated by oil. This double sealing system
protects the motor from water even if the first seal is damaged.
Cast iron feet bolted to the underside of the housing keep the pump at the proper distance
from the ground, reducing the risk of the inlet becoming clogged.

Frequently asked questions (FAQ) – WQ-80-3.0 submersible pump
What types of wastewater is the WQ-80-3.0 pump designed for?
The pump is designed for domestic wastewater, including greywater and blackwater, rainwater containing suspended solids, and dirty water with solid particles and short fibrous materials.
What are the oil chamber and dual seal used for?
The dual mechanical seal system protects the motor from water even if the first seal on the impeller side is damaged. The second seal operates submerged in the oil chamber on the motor side, providing an additional layer of protection.
How does the WQ-80-3.0 pump differ from the WQ-65-1.5?
The WQ-80-3.0 uses a dual, independent sealing system: a silicon carbide/silicon carbide hard seal on the impeller side, and a separate carbon/ceramic seal in the oil chamber on the motor side. The WQ-65-1.5 has a simpler sealing system on the impeller side, combining silicon carbide with graphite and ceramic.
Is the WQ-80-3.0 pump suitable for my installation?
The pump is suitable for installations requiring a three-phase power supply and resistance to wastewater with an elevated pH. The dual sealing system provides an additional safety margin during continuous operation. W If you have any questions, please contact our technical department.
Where can I buy the WQ-80-3.0 submersible pump?
Dambat does not sell directly. The WQ-80-3.0 pump is available from trade partners, plumbing wholesalers, and authorized online distributors.
What warranty terms apply to the WQ-80-3.0 pump?
IBO – 24 months (2 years) manufacturer's warranty. Dambat provides warranty and post-warranty service.
