WQV7-8-0.75 - submersible sewage pump with macerator
The IBO WQV submersible pump with cutting blade is a series of high-capacity units
designed for pumping sewage and dirty water that does not contain abrasive materials
such as sand. Its AISI 304 stainless steel motor housing and
3,000 rpm speed set this series apart from pumps with macerators.
The built-in float switch automatically controls pump operation, while the overcurrent circuit breaker
mounted on the power cable protects the motor if the cutting blade becomes blocked.
Who it's for
-
Homeowners and landowners – the cutting blade grinds contaminants in the sewage, reducing the risk of clogging when pumping from a septic tank.
-
Installation and service companies – the built-in float switch automates pump operation without additional control equipment.
-
Municipal utilities and household pumping stations – the series’ high capacity makes it easier to pump large volumes of sewage quickly.
-
Farms and livestock operations – the pump draws rainwater and surface water, while the cutting blade handles organic contaminants.
Applications
The WQV series of submersible pumps with macerators is designed for pumping
sewage and dirty water that does not contain abrasive materials such as sand. The pumps
are used to pump sewage from household septic tanks and drain flooded rooms,
houses and garages. They are also used in household sewage pumping stations.
The cutting blade grinds solid contaminants in the sewage before pumping,
reducing the risk of clogging the hose or pipeline. The units operate vertically,
at a maximum pumped liquid temperature of 35°C and a motor speed of
3,000 rpm, higher than that of typical submersible pumps.
WQV Series Features
The WQV series pumps feature an AISI 304 stainless steel motor housing, so it
does not corrode through constant contact with sewage. The impeller housing is made of
grey cast iron, the impeller of steel, and the cutting blade and shaft of AISI 304 stainless steel.
The overcurrent circuit breaker mounted directly on the power cable cuts off power to the
motor if the cutting blade is blocked by a hard object, protecting the motor
from overload independently of the thermal protection in the winding. The float
switch automatically controls pump operation and provides basic protection against
dry running.

Frequently asked questions (FAQ) – WQV submersible pump with grinder
What contaminants does the WQV pump shred?
The cutting blade shreds solid and fibrous contaminants in wastewater, reducing
the risk of clogging the hose or pipeline. The pump is not designed for water containing sand
or other abrasive materials.
What is the overcurrent switch on the power cable for?
The overcurrent switch cuts off power to the motor if the cutting blade is blocked by
a hard object, protecting the motor from overload independently of the thermal protection
built into the winding.
How does the WQV series differ from the CTR series?
The WQV series runs at a higher speed of 3000 rpm and has an AISI 304 stainless steel motor housing,
while the CTR uses cast iron for its motor housing and runs at the standard speed of 2850 rpm.
How do I choose the right WQV pump model for my needs?
The model selection depends on the required head and flow rate – the series includes
options from 750 W (WQV7-8-0,75) to 1500 W (WQV7-16-1,5), selected to suit the scale of the installation.
