PWDL Vertical multi-suction heads sewage pump

A robust vertical multi-suction-head submersible sewage pump engineered for reliable handling of sewage, slurry and pulp containing suspended solids and long fibers. Designed for heavy-duty industrial and municipal service, the pump combines a compact vertical motor-pump assembly with four distributed suction heads, an integral agitator and a metal cutter to minimise clogging and pit sedimentation.

Key features

• Four suction heads (one central and three at corners) that enlarge the suction area and reduce localized sediment build-up.
• Integrated agitator under the main suction head to stir settled solids and keep the suction openings clear.
• Upper metal reamer (cutter) to shred fibrous debris (rags, gloves, plastics) and prevent blockage of the suction mouths.
• Suction heads act as the support structure, eliminating the need for additional fixed mounting hardware.
• Flow-wetted parts (pump flow components) made of ductile iron for improved wear and mechanical strength.
• Vertical motor directly coupled to the pump shaft; open impeller, double-suction centrifugal design appropriate for solids-bearing fluids.

Typical applications

• Metallurgy, mining and mineral processing
• Power and coal plants
• Pulp and paper mills
• Textile and light industry
• Construction and building materials
• Municipal sewage and industrial wastewater handling

Operating limits and suitability

• Maximum liquid temperature: 60 °C
• Maximum particle size: 15 mm
• Maximum solids concentration: approximately 30% by volume (application dependent)
• Specific gravity of solids: not limited by design
• Typical recommended submergence depth (varies by model): PWDL 1.5–1.8 m; PWXL 1.5–2.0 m; PWCL 2.5–2.8 m

Model notes and options

• Model coding examples: 50PWD(X,C)L-A(B)
  • PW = sewage pump, L = vertical configuration
  • D, X, C indicate variations such as standard multi-suction head and options for upper/lower bearings
  • A/B denote impeller cuts/versions
• Available in multiple configurations to suit different submergence depths and bearing arrangements.

Why specify this pump

• Minimises downtime from clogging thanks to cutter and agitator features
• Large suction coverage reduces need for pit cleaning and maintenance interventions
• Sturdy materials and vertical, compact layout simplify installation in constrained pump pits
