Wilo-Rexa SUPRA-V



Wilo-Rexa SUPRA-V with Digital Data Interface: High energy saving and digital operating convenience for more economical waste water management.
Wilo-Rexa SUPRA-V with Digital Data Interface: High energy saving and digital operating convenience for more economical waste water management.
Wilo-Rexa SUPRA-V with Wilo-Digital Data Interface combines the best hydraulic efficiency in its class with high-efficiency IE3 motors (based on IEC 60034-30-1) and fully integrated digital networking options. This ensures minimal operating costs at high operational reliability as well as providing all connection options for modern communication – making the working day easier, which is ultimately reflected in reduced time and effort and therefore lower costs.
Recommended services
Your advantages
- Increased operational reliability and reduced service costs due to free-flowing hydraulics that are pump in non-clog design and have a large free ball passage

Construction
Submersible sewage pump as submersible monobloc unit for stationary wet well and dry well installation as well as portable wet well installation
Hydraulics
The outlet on the pressure side is designed as horizontal flange connection. The maximum possible amount of dry matter is 8 %. Vortex impellers are used.
Motor
Efficient motor technology for surface-cooled and self-cooling motors are available.
Surface-cooled motors (T motor) do not have a cooling system of their own and emit their heat directly to the surrounding fluid via the housing parts. The motors can therefore be used in immersed state for continuous duty. Depending on their size, they can also be used in non-immersed state for short-time duty.
The self-cooling motors (FK, FKT motors) have an active cooling system and transfer their waste heat to the fluid being pumped by means of an integrated heat exchanger. Therefore, these motors are suitable for continuous duty in immersed and non-immersed condition, and therefore also for dry well installation.
All motors have a sealing chamber that protects the motor from fluid ingress. It can be accessed from the outside and can optionally be monitored with a rod electrode. All filling fluids used are potentially biodegradable and environmentally safe.
The connection cable has bare cable ends and the length is customer specific. The cable inlet on T and FKT motors is longitudinally watertight.
Seal
Fluid-side and motor-side sealing is possible in the following versions depending on the motor type:
- Version H: Mechanical seal for the fluid side, rotary shaft seal for the motor side
- Version G: Two independently-acting mechanical seals
- Version K: Block seal cartridge with two independently acting mechanical seals
High efficiency motors
In addition to the standard motors, high-efficiency motors with IE3 classification (in accordance with IEC 60034-30) are also available. As these have the same basis as the standard motors, they have the same features and functions. This means that the same hydraulic systems are also available.
Ex rating
The motors are available with Ex rating in accordance with ATEX and FM.
