Description

Overview
A cast iron submersible pump range purpose-built for raw sewage, with an integrated inlet cutter mechanism and double mechanical shaft seal for reliable handling of solids-laden wastewater.

Applications
Raw sewage pumping in municipal, industrial, and wastewater treatment applications where solids content and abrasive particles are present.

Operating Conditions/Limits

  • Liquid temperature: up to 40°C
  • Density of liquid: 1.3 g/cm³
  • pH: 6 to 10
  • Protection class: IP68, Class F
  • Maximum immersion depth: 20m
  • Cable length: 8m

Performance Range
Maximum head: 42m. Maximum flow: 550 m³/h. Power range: 5.5kW to 45kW across eight models, available in 2-pole and 4-pole motor speeds.

Power Supply
380V, motor power from 5.5kW to 45kW depending on model.

Construction
Cast iron pump body and impeller (open-type, single channel, ductile iron). Integrated cutter mechanism located on the pump inlet. Double mechanical shaft seal (silicon carbide-silicon carbide / carbon graphite-ceramic). Stainless steel rotor shaft (AISI420SS). Optional overheat protector and oil/water leakage probe. Duckfoot base available for auto-coupled installation.

Available Configurations/Versions
Eight models across the range (50B25.5 through 200B445), differing in outlet size (50mm–200mm), motor power, and pole configuration. Movable soft pipe, hard pipe, and auto-coupled (duckfoot) installation options available.
