Tsurumi 200BZ475 Gray Cast Iron High-Head Wastewater Pump for Flood Control with Two-Channel Impeller

Large-scale sewage handling and intensive wastewater transfer for Australian infrastructure require metallurgy that prioritizes maximum head and structural longevity. This manual submersible unit serves as a robust technical solution for local high-capacity site drainage where heavy debris is present. Its specialized 200 mm discharge and heavy-duty cast iron construction facilitate continuous service in demanding Aussie wastewater applications.

Driven by a 75 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 57.5 m. The 4-pole induction motor is continuous-duty rated and utilizes a Star-Delta starting method to manage the 144 Amps current draw efficiently. The integrated water jacket circulates pumped liquid around the motor frame to provide cooling, allowing for stable operation at low water levels locally.

The hydraulic core features a shrouded two-channel impeller that enables a wide 76.2 mm solids passage, ensuring that suspended particles move through the pump casing without obstruction. This design provides a clear flow path for debris, reducing wear during continuous operation. The two-channel configuration ensures stable pumping characteristics while preventing clogging during intensive Aussie site water management duties.

Construction features high-grade gray cast iron for principal wetted parts, 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 electrode and an anti-wicking cable entry to safeguard the motor from moisture incursion across Australian sites.

FEATURES

• Gray cast iron construction provides maximum resistance to mechanical stress in Aussie high-capacity sewage tasks.
• Integrated water jacket circulates liquid to cool the motor, enabling extended operation at low sump levels.
• Shrouded two-channel impeller design facilitates 76.2 mm solids handling while reducing hydraulic wear.
• High-head performance reaching 57.5 m allows for effective vertical transfer in deep Aussie infrastructure sumps.
• Double-face mechanical seals with silicon carbide faces offer reliable protection against abrasive site runoff.
• Tsurumi's patented Oil Lifter ensures the shaft seals remain lubricated even if the oil volume is low.
• Internal leakage sensor electrode detects moisture intrusion into the oil chamber to protect the motor.
• Powerful 75 kW motor with Star-Delta starting ensures stable and reduced starting current for large Aussie sites.
