WQ-65-4.0 – 400 V submersible wastewater pump
The IBO WQ-65-4.0 submersible pump with a closed two-channel impeller
is a 400 V three-phase unit designed for industrial applications. It is ideal for pumping
light, pre-treated wastewater, dirty water, and rainwater. The dual, independent
the sealing 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 sealing system and oil chamber protect the motor even if one of the seals is damaged.
-
Wastewater pumping stations and permanent installations – the option of mounting on guide rails with a base coupling facilitates pump replacement without emptying the tank.
-
Companies carrying out large installations – the 400 V three-phase power supply facilitates integration with distribution boards and control cabinets.
-
High-throughput facilities – the reinforced shaft construction tolerates impacts from hard objects without reducing service life.
Applications
The WQ-65-4.0 submersible pump with a closed two-channel impeller is intended
is designed for pumping light, pre-treated wastewater, 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 technical 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 and water pH ranging from 6 to 10 – a wider range than in typical wastewater pumps, thanks to
which allows 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
thermal resistance than the popular Class B, which is important during continuous operation at elevated
liquid temperature.
Features of the WQ-65-4.0 pump
The pump features a cast-iron construction – the motor housing, body, and impeller are made of cast iron,
which ensures body rigidity and effectively dampens vibration during operation at high capacities.
The shaft is made of AISI 304 stainless steel, so it does not corrode during continuous 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 high impact 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
friction, which extends the seal’s service life during continuous contact with contaminated water.
The independent second seal on the motor side operates immersed in the oil chamber,
with a carbon/ceramic configuration, 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 bottom, reducing the risk of inlet clogging.

Frequently Asked Questions (FAQ) – WQ-65-4.0 submersible pump
What type of wastewater is the WQ-65-4.0 pump designed for?
The pump is designed for domestic 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 seal on the impeller side 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-65-4.0 pump differ from the WQ-65-1.5?
The WQ-65-4.0 uses a dual, independent sealing system – hard
a silicon carbide/silicon carbide pairing on the impeller side and a separate seal
carbon/ceramic in the oil chamber on the motor side. The WQ-65-1.5 has a simpler configuration:
sealing on the impeller side, combining silicon carbide with graphite and ceramic.
Will the WQ-65-4.0 pump work in my installation?
The pump is suitable for installations requiring three-phase power and resistance
for wastewater with elevated pH, while the dual sealing system provides an additional safety margin
of safety during continuous operation. If in doubt, we encourage you to
contact with the technical department.
Where can I buy the WQ-65-4.0 submersible pump?
Dambat does not sell directly. The WQ-65-4.0 pump is available
from trade partners, installation wholesalers, and authorized
online distributors.
What warranty terms apply to the WQ-65-4.0 pump?
IBO – 24 months (2 years) manufacturer’s warranty. Warranty and post-warranty service
provided by Dambat.
