Tsurumi 100BZ42.2 Gray Cast Iron Submersible Wastewater Pump for Manholes with Single-Channel Impeller

Efficiently transferring large volumes of wastewater in Australian commercial facilities requires metallurgy that withstands constant immersion and abrasive site conditions. This manual submersible unit is configured for sewage pumping and industrial effluent management, providing a durable solution for local sumps. Its specialized channel hydraulics ensure long-term structural integrity in environments where heavy solids and fibrous materials would cause standard equipment to fail.

Driven by a 2.2 kW / 415v three-phase induction motor, the system manages a maximum flow capacity of up to approximately 1800 L/Min and reaches a peak head of up to approximately 8.7 m. The 4-pole motor maintains a 5.1 Amps rated current and utilizes a Direct on Line starting method for immediate activation. This power rating ensures consistent discharge performance through a 100 mm discharge bore for demanding Aussie drainage cycles.

The unit features a shrouded single-channel impeller that enables a wide 80 mm solids passage, ensuring that suspended particles move through the pump casing without obstruction. The wide hydraulic passage allows solids to pass freely, reducing the likelihood of blockage in sewage applications. This arrangement is ideal for liquids carrying heavy debris, as the shrouded design protects the hydraulic path from clogging.

Structural integrity is maintained through a gray cast iron body and casing, with a 420 stainless steel shaft for enhanced mechanical strength. Sealing is managed by dual mechanical seals isolated in an oil chamber featuring a proprietary Oil Lifter for cooling. Protection is provided by a circle thermal protector that interrupts the circuit during overcurrent or heat buildup, while an anti-wicking cable entry shields the motor windings.

FEATURES

• Manufactured from high-grade gray cast iron to ensure outstanding durability in Australian wastewater applications.
• Shrouded single-channel impeller configuration facilitates the passage of 80 mm solids without risking internal clogging.
• Double-face mechanical seal with silicon carbide lower faces provides reliable protection against abrasive particles.
• Tsurumi's original Oil Lifter forcibly supplies oil to the seal faces, ensuring reliability even at low lubricant 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 moisture from entering the motor via conductor strands.
• Back pull-out design enables easier maintenance by allowing motor separation with the impeller attached.
• Large 100 mm discharge bore supports high-volume transfer for intensive Australian site dewatering tasks.
