Tsurumi 200BZ445 Gray Cast Iron Submersible Sewage Pump for Manholes with Two-Channel Impeller

Municipal wastewater management and large-scale site dewatering across Australia require a pumping solution that combines high-capacity hydraulics with reliable performance. This manual submersible unit is configured for handling sewage and industrial wastewater in demanding Australian factory sumps without manual oversight. Its heavy-duty gray cast iron metallurgy ensures structural durability in Aussie environments where standard equipment would succumb to mechanical stress.

Operating with a 45 kW / 415v three-phase motor, the unit achieves a peak flow of up to approximately 9375 L/Min and reaches a maximum head of up to approximately 41.4 m. The 4-pole induction motor is continuous-duty rated and utilizes a Star-Delta starting method to manage the 87 Amps current draw. This configuration ensures stable pumping performance for intensive industrial dewatering across varied Australian site conditions and municipal sumps.

The hydraulic assembly features a shrouded two-channel impeller manufactured from gray cast iron to enable 76.2 mm solids passage. This design provides a wide flow path that moves suspended debris through the pump without obstruction. The two-channel configuration ensures stable pumping characteristics while preventing clogging during intensive Aussie site water management duties.

Mechanical construction utilizes high-grade gray cast iron, 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 a built-in leakage sensor and an anti-wicking cable entry to safeguard the motor from moisture, while the Turbine Oil lubrication ensures reliable shaft sealing.

FEATURES

• Gray cast iron construction provides the mechanical strength required for intensive Australian municipal service.
• Shrouded two-channel impeller design facilitates 76.2 mm solids handling while reducing hydraulic friction.
• High-capacity 45 kW motor with Star-Delta starting ensures reduced starting current for large Aussie sumps.
• Double-face mechanical seals with silicon carbide lower faces offer superior resistance to abrasion.
• Patented Oil Lifter technology supplies lubricating oil to the seal faces even if the oil volume is low.
• Miniature thermal protectors embedded in the windings proactively interrupt the circuit during dry-running.
• Internal leakage sensor electrode detects moisture intrusion into the oil chamber to protect the motor.
• Large 200 mm discharge bore supports flow rates up to 9375 L/Min for rapid Australian site dewatering.
