Vortex pump REXA PRO series

for wastewaterelectricsubmersible

Highly effective thanks to efficiency-optimized single-channel impellers Safe to operate due to low-clogging vortex impellers Verified safety: Ex-rated in accordance with ATEX as standard Energy-efficient IE3 motor technology available as an option Design Submersible sewage pump for continuous duty for stationary and portable wet well installation, as well as for stationary dry well installation. Application Pumping of Untreated sewage Sewage containing faeces in accordance with (DIN) EN 12050-1 Wastewater Equipment/function Leakage detection for the motor compartment Winding temperature monitoring with bimetallic strip Optional external pencil electrode for sealing chamber control Single-phase version with capacitor switchgear Construction Submersible sewage pump as submersible monobloc unit for stationary and portable wet well installation, as well as stationary dry well installation. Hydraulics The outlet on the pressure side is designed as horizontal flange connection. The maximum possible dry matter is 8 % (depending on the hydraulics) Vortex and single-channel impellers are used. Motor The motor versions used are single-phase current and three-phase current surface-cooled motors. For single-phase current motors, the condenser is installed in a separate switchgear. Depending on performance, activation is carried out via direct startup or star/delta startup. The motor is cooled by the medium around it (pumped fluid or air). The waste heat is dissipated via the motor housing.
