100GPM Mechanical Rexa SUPRA Wilo Sewage Pump Residential

Product Specification

Wilo-Rexa SUPRA Transport sewage efficiently and economically. Ready for networking in digital wastewater management with Wilo-DDI

“Whether untreated or pre-treated sewage – the submersible pumps of the Wilo-Rexa SUPRA series have been developed for the various requirements in modern sewage pumping. Vortex, single-channel or multi-channel impeller, die Wilo-Rexa SUPRA always provides a combination of clogging resistance and energy efficiency. As such, the Rexa SUPRA is ideal for safe and economical sewage transport. In combination with the optionally available IE3 motors (in accordance with IEC 60034-30-1), the Wilo-Rexa SUPRA also reduces operating costs. The Wilo-DDI can be integrated to meet the requirements of digital connectivity. The Wilo-Rexa SUPRA thus offers all the features of modern communication connectivity and makes everyday work really easy."

Materials Hydraulic and motor housing: EN-GJL-250 (ASTM A48 Class 35/40B) or EN-GJS-500-7 (ASTM A536 70-50-05) Impeller: EN-GJL-250 (ASTM A48 Class 35/40B) or EN-GJS-500-7 (ASTM A536 70-50-05) Seals: Static: NBR (nitrile) On the fluid side: SiC/SiC On the motor side: SiC/SiC or C/Cr Shaft: Stainless steel AISI 1.4021 (420)

Construction Hydraulics The outlet on the discharge side is designed as horizontal flange connection. The maximum possible dry matter is 8 %. The following impeller shapes are available: Vortex impeller Single-channel impeller Multi-channel impeller

T motor Surface-cooled submersible motor without cooling system for wet well installation. The waste heat of the motor is dissipated directly to the surrounding fluid via the housing parts. The motor itself is dry. Permanently lubricated rolling bearings are used as motor bearings. The connection cable is longitudinally watertight and has bare cable ends. Depending on the size and the motor power, the motors can be installed dry in short-time duty. FK motor Self-cooling submersible motor with active cooling system for wet well and dry well installation. For cooling, the motor is filled with medicinal white oil. An impeller on the motor shaft allows the coolant to circulate continuously. The cooling flange transfers the waste heat to the pumped fluid. The cooling system itself is not pressurised. Permanently lubricated rolling bearings are used as motor bearings. The connection cable is longitudinally watertight and has bare cable ends.

FKT motor Self-cooling submersible motor with active cooling system for wet well and dry well installation. The separate cooling system is filled with a water-glycol mixture. An impeller circulates the coolant continuously. The cooling flange transfers the waste heat to the pumped fluid. The motor compartment is dry, and the cooling system itself is pressureless. Permanently lubricated rolling bearings are used as motor bearings. The connection cable is longitudinally watertight and has bare cable ends. Seal All the motors have a sealing chamber to protect the motor from fluid entering through the seal on the fluid side. The sealing chamber is accessible from the outside. On request, the sealing chamber can be monitored with a pencil electrode. 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

Operating fluids All operating fluids are potentially biodegradable and harmless to the environment: White oil Water-glycol mixture (water-polluting class 1 according to VwVwS) Motor efficiency classes (based on IEC 60034-30) In addition to the standard motors, IE3 motors are also available. The motors are based on the same design as the standard motors. This means that the motors are identical in terms of equipment and function.

Scope of delivery Pump Fitted accessories as ordered Installation and operating instructions Options Standard voltages and special voltages Operation in fluids up to 60 °C (140 °F) Motor-dependent monitoring devices: Winding monitoring with PTC sensor Sealing chamber Motor/terminal room Motor bearing temperature Oscillation sensor Ceram coating for abrasive and corrosive fluids Digital Data Interface for simple integration into the system controls and monitoring of the pump: Easy connectivity via Ethernet interface Easy to integrate into existing control technology by using standard protocols
