WQ 65-1.5 - 400 V submersible wastewater pump
The IBO WQ 65-1.5 submersible pump with a closed two-channel impeller is an industrial unit powered by 400 V three-phase electricity, designed for pumping lightly treated wastewater, dirty water, and rainwater. The oil chamber protects the motor from direct water ingress if the mechanical seal behind the impeller is damaged.
Who it's for
-
Industrial plants and wastewater treatment plants - the 400 V three-phase power supply and oil chamber protect the motor during continuous operation in demanding conditions.
-
Companies carrying out large-scale installations - three-phase power makes integration with distribution boards and control cabinets easier.
-
Wastewater pumping stations and municipal utilities - the closed two-channel impeller ensures high flow when pumping domestic wastewater.
-
Large farms with high water demand - a head of up to 20 m allows water to be pumped over longer distances.
Applications
The WQ 65-1.5 submersible pump with a closed two-channel impeller is designed for pumping lightly 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 from residential and utility buildings, as well as wastewater treatment plants.
The unit operates in a vertical position, with a maximum pumped liquid temperature of 40°C and water pH in the range of 6–10. The WQ 65-1.5 400 V submersible pump achieves a head of up to 20 m at a flow rate of up to 630 l/min.
Features of the WQ 65-1.5 pump
The WQ 65-1.5 pump features a cast-iron construction - the motor housing, body, and impeller are made of cast iron. The shaft is made of AISI 304 stainless steel, and the mechanical seal operates with a SiC/graphite seal pair.
The oil chamber protects the motor from direct water ingress if the mechanical seal behind the impeller is damaged. Cast-iron feet bolted to the underside of the housing keep the pump at the correct distance from the ground, reducing the risk of the inlet becoming clogged. Three-phase power requires an external control cabinet with motor overload protection.

Frequently asked questions (FAQ) – WQ 65-1.5 submersible pump
What types of wastewater is the WQ 65-1.5 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 is the oil chamber in the WQ 65-1.5 pump used for?
The oil chamber protects the motor from direct water ingress if the mechanical seal behind the impeller is damaged, extending the pump's safe operating life.
How does the WQ 65-1.5 pump differ from the WQ PROFESSIONAL series?
The WQ 65-1.5 is powered by three-phase 400 V and does not have a built-in float switch. It requires an external control cabinet. It also has an oil chamber that protects the motor if the seal is damaged. The WQ PROFESSIONAL series is powered by single-phase 230 V and has a built-in float switch, allowing it to operate automatically.
Will the WQ 65-1.5 pump work in my installation?
The pump is suitable for installations requiring a head of up to 20 m at a flow rate of up to 630 l/min, as well as applications with three-phase power. W If you have any doubts about choosing a pump, please contact our technical department.
