Tsurumi 200BZ455 Gray Cast Iron Wastewater Pump for Industrial Wastewater Handling with Two-Channel Impeller

Industrial sewage handling and high-capacity drainage for Australian manufacturing facilities require metallurgy that withstands continuous duty and mechanical stress. This manual submersible unit is configured specifically for large-scale sewage transfer where debris and fibrous matter are common. Its robust cast iron construction and integrated water jacket ensure continuous service in environments where standard iron equipment would succumb to thermal stress locally.

Powered by a 55 kW / 415v three-phase motor, the pumping system achieves a maximum head of up to approximately 46.5 m and provides a flow capacity of up to approximately 9375 L/Min. This 4-pole dry-type induction motor utilizes a Star-Delta starting method and maintains a rated current of 110 Amps. The integrated water jacket utilizes the pumped liquid to cool the motor frame, allowing for stable operation even during extended low-water levels in Aussie sumps.

The hydraulic configuration utilizes a shrouded two-channel impeller manufactured from gray cast iron to enable 76.2 mm solids passage. This design creates a stable flow path that moves suspended debris through the 200 mm discharge without obstruction. Such an arrangement is essential for maintaining consistent flow when managing liquids with heavy suspended matter in demanding Australian factory sumps.

Structural integrity is maintained through a gray cast iron body and casing, with a 420 stainless steel shaft and Insulation Class F motor for thermal stability. Sealing integrity is provided by a double-face mechanical seal in an oil chamber featuring a proprietary Oil Lifter. Protection is enhanced by miniature thermal protectors, a leakage sensor, and an anti-wicking cable entry block that protects the motor from moisture incursion locally.

FEATURES

• Heavy-duty gray cast iron construction ensures structural longevity for Australian industrial sewage duty.
• Integrated water jacket allows for extended continuous operation even at low liquid levels in Aussie sumps.
• Shrouded two-channel impeller configuration enables efficient 76.2 mm solids handling while reducing mechanical wear.
• Powerful 55 kW motor with Star-Delta starting supports reduced starting current for high-volume drainage across Australia.
• Double-face mechanical seals with silicon carbide lower faces provide reliable protection against abrasion.
• Patented Oil Lifter technology keeps seal faces lubricated even if the lubricant volume falls to low levels.
• Internal leakage sensor electrode provides early detection of moisture intrusion into the oil chamber to protect the motor.
• Miniature thermal protectors embedded in the windings proactively interrupt the circuit during thermal overload.
