Tsurumi 100BZ43.7 Gray Cast Iron Wastewater Pump for Flood Control with Single-Channel Impeller

Managing municipal sewage and wastewater for Australian infrastructure projects requires a pumping solution with significant solids handling capability. This manual submersible unit serves as a robust technical solution for local sewage transfer and industrial drainage where large particles are present. Its heavy-duty cast iron metallurgy is rated for continuous duty in demanding environments, ensuring stable site water management across varied Aussie climates.

Operating with a 3.7 kW / 415v three-phase motor, the system manages a maximum flow capacity of up to approximately 2100 L/Min and reaches a peak head of up to approximately 11.4 m. The 4-pole dry-type induction motor maintains a rated current of 7.7 Amps and utilizes a Direct on Line (D.O.L.) starting method. This configuration ensures stable pumping characteristics for large-scale sewage transfer across diverse Australian commercial sites.

The hydraulic configuration utilizes a shrouded single-channel impeller to create wide passages that enable the displacement of 80 mm solids. This design creates a stable flow path that moves suspended debris through the 100 mm discharge without obstruction. The wide internal passage reduces the likelihood of blockage when managing liquids with heavy suspended matter in local industrial sumps.

Mechanical construction utilizes gray cast iron for principal components, complemented by a 420 stainless steel shaft for superior mechanical strength. Sealing integrity is provided by dual mechanical seals in an oil chamber featuring a patented Oil Lifter for continuous lubrication. Protection is enhanced by a circle thermal protector and an anti-wicking cable entry block that safeguards the motor from moisture incursion locally.

FEATURES

• Gray cast iron construction provides maximum resistance to mechanical stress in Australian municipal sumps.
• Shrouded single-channel impeller design facilitates 80 mm solids handling while reducing hydraulic friction.
• Dual mechanical seals with silicon carbide lower faces offer superior resistance to abrasion and liquid ingress.
• Tsurumi's patented Oil Lifter ensures the shaft seals remain lubricated even if the lubricant volume is low.
• Circle thermal protector built into the motor housing directly cuts the circuit during excessive heat or overcurrent.
• Anti-wicking cable entry block uses a molded rubber seal to prevent water from wicking into the motor housing.
• Back pull-out configuration allows for inspection of the hydraulic parts without disconnecting the discharge piping.
• Large 100 mm discharge bore facilitates high-capacity transfer for Aussie industrial and municipal sewage.
