PW Horizontal sewage centrifugal pump

Robust single-stage, single-suction cantilever centrifugal pump designed for handling sewage and wastewater containing suspended solids and long fibers. Constructed with a cast-iron or stainless-steel pump body (PWF version uses 304 stainless steel for all flow parts), the unit is suitable for media up to 100°C and for corrosive acidic or alkaline effluents when the corrosion-resistant variant is specified.

Key features

• Handles sewage and industrial wastewater with suspended solids and long fibers
• Pump body materials: cast iron or 304 stainless steel (PWF corrosion-resistant version)
• Single-stage, single-suction, cantilever centrifugal design for reliable, clog-resistant operation
• Axial horizontal inlet; outlet can be installed horizontally or vertically to suit piping layouts
• Double-end mechanical shaft seal for improved sealing reliability
• Direct drive on a common baseplate via elastic coupling for compact, low-maintenance installation
• Recommended: install a suction inlet filter when treating industrial sewage to block large debris and extend service life

Performance range

• Flow: 14–1,000 m3/h
• Head: 9–32 m
• Motor power: 4–132 kW
• Speed: 730–2,950 rpm
• Nominal bore (caliber): 50–100 mm
• Maximum medium temperature: ≤ 100 °C

Typical applications

• Municipal and industrial sewage transfer
• Wastewater treatment plants and pumping stations
• Chemical, petroleum and light industry effluent handling
• Food, pharmaceutical and brewing process wastewater
• Environmental protection and industrial drainage systems

Benefits for B2B buyers

• Versatile configuration options (material and outlet orientation) to fit site requirements
• Corrosion-resistant variant available for aggressive media
• Efficient, stable operation with straightforward installation and servicing
• Suitable for robust industrial use where solids-laden and fibrous wastes are present

Ordering and specification tips

• Specify required pump material (cast iron or 304 stainless steel), required flow/head point, motor power and rotational speed, flange orientation (horizontal or vertical outlet), and maximum expected solids/fiber content so the correct model and impeller configuration can be selected.
