WQV7-12-1,1 - submersible sewage pump with grinder
The IBO WQV submersible pump with cutting blade is a series of high-capacity units
designed for pumping wastewater and dirty water that does not contain abrasive particles
such as sand. Its AISI 304 stainless steel motor housing and
3000 rpm speed set this series apart from other pumps with grinders.
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
-
Home and landowners – the cutting blade shreds contaminants in wastewater, reducing the risk of clogging when pumping out septic tanks.
-
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 larger volumes of wastewater 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 grinders is designed for pumping
wastewater and dirty water that does not contain abrasive particles such as sand. The pumps
are used to pump wastewater from household septic tanks and drain flooded rooms,
homes, and garages. They are also used in household wastewater pumping stations.
The cutting blade shreds solid contaminants in wastewater before it is pumped,
reducing the risk of clogging the hose or pipeline. The units operate vertically,
with a maximum pumped liquid temperature of 35°C and a motor speed of
3000 rpm, higher than that of typical submersible pumps.
WQV Series Features
WQV series pumps feature an AISI 304 stainless steel motor housing, so it does not corrode in constant contact with wastewater. The impeller housing is made of gray cast iron, the impeller is made of steel, and the cutting blade and shaft are made of AISI 304 stainless steel.
An 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 grinder pump
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 particles.
What is the overcurrent circuit breaker on the power cable for?
The overcurrent circuit breaker cuts 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 gray cast iron for the motor housing and runs at the standard 2850 rpm.
How do you choose the right WQV pump model for your needs?
The choice of model depends on the required lifting height and capacity - the series includes
variants ranging from 750 W (WQV7-8-0,75) to 1500 W (WQV7-16-1,5), selected to suit the scale of the installation.
