Tsurumi 100BZ47.5 Gray Cast Iron Submersible Wastewater Pump for Lifting Stations with Single-Channel Impeller

Managing large-scale sewage and wastewater transfer across Australia requires a pumping solution with maximum head and reliable solids handling. This manual submersible unit provides a robust technical solution for handling raw sewage and liquids carrying large suspended solids in demanding factory sumps. Its combination of specialized channel hydraulics and cast iron metallurgy ensures continuous service in abrasive Aussie site conditions.

Operating with a 7.5 kW / 415v three-phase motor, the unit achieves a peak flow of up to approximately 2100 L/Min and reaches a maximum head of up to approximately 17 m. The 4-pole dry-type induction motor is continuous-duty rated and maintains a 16.1 Amps current draw. This configuration ensures stable pumping performance for intensive industrial dewatering across varied Australian site conditions and municipal wastewater systems.

The hydraulic core features a shrouded single-channel impeller manufactured from gray cast iron, enabling the passage of solids up to 80 mm. This arrangement provides a wide flow path that moves suspended debris through the pump casing without obstruction. Such a configuration is essential for handling solids-laden wastewater without risking mechanical failure during intensive Aussie service.

Mechanical construction utilizes high-grade gray cast iron, supported by dual mechanical seals and a patented Oil Lifter for cooling. Structural components are protected by an internal circle thermal protector and an anti-wicking cable entry that shields the motor from moisture. The unit is rated for continuous duty and features Insulation Class F, ensuring thermal stability during heavy-duty Australian drainage tasks.

FEATURES

• Gray cast iron construction offers exceptional durability for Australian industrial dewatering.
• Shrouded single-channel impeller configuration facilitates the passage of 80 mm solids while reducing mechanical wear.
• High-grade 420 stainless steel shaft provides excellent mechanical strength for continuous Australian site duty.
• Double-face mechanical seals with silicon carbide faces offer superior protection against abrasive site runoff.
• Tsurumi's original Oil Lifter maintains a stable lubricating environment for the shaft seal at low oil volumes.
• Circle thermal protector built into the motor housing proactively interrupts the circuit during thermal overload.
• Watertight cable entry with an anti-wicking block prevents water from entering the motor via conductor strands.
• Insulation Class F rating ensures the motor withstands heat buildup during intensive Aussie wastewater transfer.
