Tsurumi 200BZ437 Gray Cast Iron Sewage Pump for Industrial Wastewater Handling with Two-Channel Impeller

Managing industrial wastewater and high-capacity drainage for the Australian manufacturing sector requires metallurgy that withstands suspended solids and continuous service duty. This manual submersible unit provides a robust technical solution for handling wastewater and sewage in demanding Australian factory sumps. Its specialized channel hydraulics facilitate continuous service where standard iron equipment would succumb to mechanical wear.

Driven by a 37 kW / 415v three-phase motor, the system manages a maximum flow capacity of up to approximately 9375 L/Min and reaches a peak head of up to approximately 33.4 m. The 4-pole dry-type induction motor is rated for continuous duty and utilizes a Star-Delta starting method to manage the 72 Amps current draw. This configuration ensures stable pumping performance for high-head dewatering across varied Australian site conditions.

The unit features a shrouded two-channel impeller manufactured from gray cast iron to enable 76.2 mm solids passage. This design provides a wide hydraulic passage that allows debris to move through the pump without obstruction, minimizing wear and reducing the risk of clogging. This configuration is essential for maintaining reliable flow when managing liquids with heavy suspended matter in Australian industrial sumps and site drainage networks.

Construction features high-grade gray cast iron for principal wetted parts, supported by a 420 stainless steel shaft and Insulation Class F motor for thermal stability. Sealing is managed by dual mechanical seals in an oil chamber featuring Tsurumi's original Oil Lifter for cooling. Protection is reinforced by miniature thermal protectors and a built-in leakage sensor electrode that detects moisture intrusion into the oil chamber, protecting the motor windings locally.

FEATURES

• Gray cast iron build ensures superior structural longevity for Australian wastewater management.
• Shrouded two-channel impeller configuration facilitates the passage of 76.2 mm solids without risking internal clogging.
• High-head performance reaching 33.4 m allows for effective vertical transfer in deep Aussie industrial sumps.
• Double-face mechanical seal with silicon carbide faces provides reliable protection against abrasive particles.
• Tsurumi's Oil Lifter technology keeps seal faces lubricated even if the oil volume falls to low levels.
• Miniature thermal protectors embedded in the motor windings directly cut the circuit during electrical overload.
• Internal leakage sensor electrode provides early detection of 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 Aussie site dewatering tasks.
