Tsurumi PU Series Waste Water Pumps

The PU Series is a submersible sewage pump range designed for raw sewage, wastewater and water carrying solid matter. Its vortex impeller and wide pump casing help move liquid with reduced obstruction, making it a practical option for light sewage, wastewater transfer and sump applications where solids may be present. Made from glass-fibre reinforced resin and stainless steel, the range is lightweight, corrosion-resistant and easier to handle during installation or maintenance.

Key features

• Vortex impeller design: The PU Series uses a vortex impeller to help move sewage, wastewater and water carrying solid matter through the pump with reduced obstruction.
• Wide pump casing: The casing design helps provide solids passage for light sewage and wastewater applications where foreign objects may enter the water.
• Lightweight corrosion-resistant construction: Glass-fibre reinforced resin and stainless steel construction helps reduce weight while supporting corrosion resistance.
• PU model range: The range includes 40mm, 50mm and 80mm discharge bore models, with motor outputs from 0.15kW to 3.7kW.
• Solids passage options: PU models provide 35mm solids passage on 40mm and 50mm models, while 80mm models provide 46mm solids passage.
• Automatic models available: Automatic models use an integral control circuit and two low voltage float switches, allowing the pump to respond to changing water levels.
• Auto-alternation option: Auto-alternation models can be used with an automatic model so two pumps operate alternately without a control panel.
• TOK guide rail compatibility: The PU Series can be used with TOK guide rail fittings across the motor output range, helping simplify removal and maintenance in sump installations.
• Mechanical seal protection: A double mechanical seal with silicon carbide faces operates with an Oil Lifter, helping maintain lubrication around the seal faces.
• Motor protection: Built-in thermal protection helps protect the motor against excessive heat from overcurrent or run-dry conditions.
• Liquid paraffin lubricant: Liquid paraffin is used as the lubricating oil, supporting use in applications such as decorative water features, fishponds and aquaculture.
