Tsurumi 200BZ430 Gray Cast Iron Submersible Wastewater Pump for Flood Control with Two-Channel Impeller

Handling intensive sewage transfer and industrial wastewater for Australian commercial facilities requires a pumping solution with superior flow and mechanical strength. This manual submersible unit is configured specifically for heavy-duty sewage management in factory sumps where large solids are present. Its robust cast iron construction ensures continuous service where standard materials would succumb to the mechanical stress of Aussie dewatering cycles.

Powered by a 30 kW / 415v three-phase motor, the pumping system achieves a maximum head of up to approximately 28.8 m and provides a flow capacity of up to approximately 9375 L/Min. This 4-pole dry-type induction motor is rated for continuous duty and utilizes a Star-Delta starting method to maintain a 59 Amps current draw. This configuration ensures dependable liquid transfer for high-volume drainage across varied Australian industrial site conditions.

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 local factory sumps.

Structural integrity is maintained through a gray cast iron body and motor frame, 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 and an anti-wicking cable entry block that protects the motor from moisture incursion in Australian sumps.

FEATURES

• Gray cast iron construction provides maximum resistance to mechanical stress in Aussie heavy-duty sewage tasks.
• Shrouded two-channel impeller configuration enables efficient 76.2 mm solids handling without internal clogging.
• Powerful 30 kW motor with Star-Delta starting supports reduced starting current for high-volume transfer locally.
• Double-face mechanical seal with silicon carbide faces provides reliable protection against abrasive site runoff.
• Patented Oil Lifter technology keeps the mechanical seal faces lubricated even if the lubricant volume falls.
• Miniature thermal protectors embedded in the motor windings proactively interrupt the circuit during overload.
• Internal leakage sensor electrode provides early detection of moisture intrusion into the oil chamber.
• Large 200 mm discharge bore allows for flow rates up to 9375 L/Min in demanding Aussie industrial sumps.
