WQ-80-3.0 – 400 V submersible wastewater pump
The IBO WQ-80-3.0 submersible pump with a two-channel closed impeller
is a 400 V three-phase-powered unit designed for industrial applications. It is ideal for pumping
light, pretreated wastewater, dirty water, and rainwater. The dual, independent
the seal system and oil chamber protect the motor from water even
if one of the seals is damaged.
Who it is for
-
Industrial plants and wastewater treatment facilities – the dual seal system and oil chamber protect the motor even if one of the seals is damaged.
-
Wastewater pumping stations and permanent installations – installation on guide rails with a foot coupling enables pump replacement without emptying the tank.
-
Companies carrying out large installations – the 400 V three-phase power supply facilitates integration with switchboards and control cabinets.
-
High-duty plants – the reinforced shaft construction tolerates impacts from hard objects without reducing service life.
Applications
The WQ-80-3.0 submersible pump with a two-channel closed impeller
is designed to pump light, pretreated wastewater, dirty water, and rainwater.
The pump is suitable for domestic wastewater, including gray and black water,
containing solid particles and short fibrous materials, originating, among other sources,
from residential and utility buildings, as well as wastewater treatment plants.
The unit operates in a vertical position, at a maximum pumped-liquid temperature of
up to 40°C, with water pH ranging from 6 to 10—a wider range than in typical wastewater pumps, thanks to
allowing it to handle both slightly acidic and alkaline wastewater without accelerated
corrosion of cast-iron components. The motor winding's Class F insulation provides a greater margin
higher thermal resistance than the popular Class B, which is important for continuous operation at elevated
liquid temperature.
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,
which provides body rigidity and effectively dampens vibration during high-capacity operation.
The shaft is made of AISI 304 stainless steel, so it does not corrode during constant contact
with wastewater and maintains precise impeller alignment throughout its service life.
The short shaft support and rigid bearing arrangement further reduce vibration, ensuring that
the shaft withstands heavy impact loads even during occasional contact with hard
objects.
The impeller-side seal uses a silicon carbide/silicon carbide configuration –
a hard material combination with high abrasion resistance and a low coefficient
friction, which extends the seal's service life during constant contact with contaminated water.
The independent second seal on the motor side operates immersed in the oil chamber,
with carbon/ceramic seals, cooled and lubricated with oil. This dual sealing system
protects the motor from water even if the first seal is damaged.
Cast-iron stands bolted to the bottom of the housing keep the pump at the proper distance
above the ground, reducing the risk of inlet blockage.

Frequently Asked Questions (FAQ) – WQ-80-3.0 submersible pump
What type of wastewater is the WQ-80-3.0 pump designed for?
The pump is designed for domestic and household wastewater, including grey
and black wastewater, rainwater with suspended solids, and dirty water containing solid particles
and short fibrous materials.
What is the purpose of the oil chamber and dual seal?
The dual mechanical seal system protects the motor from water even
if the first impeller-side seal is damaged – the second
the seal operates immersed 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 – hard
silicon carbide/silicon carbide pairing on the impeller side and a separate seal
carbon/ceramic seal in the oil chamber on the motor side. The WQ-65-1.5 has a simpler system
impeller-side seal, combining silicon carbide with graphite and ceramic.
Will the WQ-80-3.0 pump work in my installation?
The pump is suitable for installations requiring three-phase power supply and resistance
for wastewater with elevated pH, while the dual sealing system provides an additional safety margin
safe continuous operation. If in doubt, we encourage you to
contact with the 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
through trade partners, installation wholesalers, and authorized
online distributors.
What warranty terms apply to the WQ-80-3.0 pump?
IBO – 24 months (2 years) manufacturer’s warranty. Warranty and post-warranty service
provided by Dambat.
