Tsurumi 80BZ41.5 Gray Cast Iron Submersible Sewage Pump for Lifting Stations with Single-Channel Impeller

Managing raw sewage and solids-laden wastewater in Australian municipal systems requires equipment built for reliable solids handling and long-term structural integrity. This manual submersible unit serves as a robust option for local wastewater treatment and site drainage where heavy debris is present. Its heavy-duty cast iron metallurgy is configured for continuous immersion in Aussie sewage environments, ensuring stable system duty without frequent manual intervention.

Powered by a 1.5 kW / 415v three-phase motor, the pumping system manages a maximum flow capacity of up to approximately 1410 L/Min and reaches a peak head of up to approximately 6.3 m. This 4-pole dry-type induction motor utilizes a Direct on Line (D.O.L.) starting method and maintains a rated current of 4.1 Amps. Such a configuration ensures stable pumping performance during effluent transfer cycles across diverse Australian site conditions.

The hydraulic core features a shrouded single-channel impeller that creates wide internal passages to facilitate the displacement of solids up to 80 mm. The wide hydraulic passage allows solids to pass through the pump with minimal restriction, helping maintain stable pumping performance in sewage applications. By providing a clear flow path through the 80 mm discharge, the channel design reduces the likelihood of blockage from fibrous matter and solids common in Aussie sewage sumps.

Construction utilizes high-grade gray cast iron for the pump casing and motor frame, supported by a 420 stainless steel shaft. Sealing integrity is provided by a double-face mechanical seal in an oil chamber featuring Tsurumi's patented Oil Lifter for continuous cooling. Protection is reinforced by a circle thermal protector built into the motor housing and an anti-wicking cable entry block that safeguards the dry-type motor from potential moisture incursion.

FEATURES

• Gray cast iron construction provides the mechanical strength and durability required for Australian sewage handling.
• Shrouded single-channel impeller enables a wide 80 mm solids passage to minimize clogging from fibrous matter.
• Double-face mechanical seal with silicon carbide lower faces offers superior resistance to abrasion and liquid ingress.
• Patented Oil Lifter technology keeps the mechanical seal faces lubricated even if the oil volume falls to low levels.
• Circle thermal protector embedded in the motor housing proactively interrupts the circuit during thermal or electrical overload.
• Watertight cable entry with an anti-wicking block prevents moisture from entering the motor through capillary action.
• Compact 80 mm discharge bore facilitates integration into local municipal sumps and standard drainage networks.
• Back pull-out design allows for simplified maintenance and inspection of the impeller without full motor disassembly.
