Tsurumi 100BZ411H Gray Cast Iron High-Head Sewage Pump for Flood Control with Single-Channel Impeller

High-head sewage pumping in Australian industrial sumps requires metallurgy that withstands significant vertical lift and demanding site conditions. This manual submersible unit is engineered specifically for raw sewage and wastewater management, providing a durable technical solution for local high-lift drainage requirements. Its heavy-duty cast iron metallurgy and high-head characteristics ensure long-term structural integrity in demanding Australian municipal environments.

Powered by an 11 kW / 415v three-phase motor, the pumping system achieves a maximum head of up to approximately 23 m and a flow capacity of up to approximately 2820 L/Min. This induction motor is continuous-duty rated through a 100 mm discharge bore and utilizes a Star-Delta starting method to maintain a 22.8 Amps current draw. The high-head design allows for effective liquid transfer in deep Aussie sumps where significant vertical lift is required.

The unit features a shrouded single-channel impeller that enables 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 hydraulic arrangement is ideal for liquids bearing heavy suspended solids, as the shrouded design provides a clear flow path to prevent clogging.

Construction features high-grade gray cast iron for principal wetted parts, supported by a 420 stainless steel shaft and dual mechanical seals for durability. Protection is provided by miniature thermal protectors embedded in the motor windings that interrupt the circuit during heat buildup. The unit utilizes an anti-wicking cable entry to protect the motor from moisture, while the Turbine Oil lubrication ensures reliable shaft sealing.

FEATURES

• Gray cast iron casing and motor frame offer maximum durability for Australian high-head sewage pumping.
• Shrouded single-channel impeller enables efficient 80 mm solids handling while reducing hydraulic friction.
• High-head performance reaching 23 m allows for effective liquid transfer in deep local industrial sumps.
• Double-face mechanical seals with silicon carbide lower faces provide superior protection against ingress.
• Tsurumi's patented Oil Lifter ensures the shaft seals remain lubricated even if the lubricant volume is low.
• Miniature thermal protectors embedded in the windings proactively interrupt the circuit during dry-running.
• Watertight cable entry with an anti-wicking block prevents water from wicking into the motor housing.
• Large 100 mm discharge bore facilitates high-volume transfer for intensive Australian municipal wastewater tasks.
