Tsurumi 200BZ622 Gray Cast Iron Wastewater Pump for Lifting Stations with Two-Channel Impeller

Large-scale municipal wastewater transfer and heavy-duty drainage for Australian infrastructure require metallurgy that prioritizes maximum flow and structural longevity. This manual submersible unit serves as a robust technical solution for handling raw sewage and liquids carrying large suspended solids in demanding local sumps. Its specialized 200 mm discharge and cast iron metallurgy facilitate continuous service in demanding Aussie wastewater applications.

Driven by a 22 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 23.5 m. The 6-pole induction motor is continuous-duty rated and utilizes a Star-Delta starting method to manage the 47 Amps current draw efficiently. This configuration ensures stable pumping performance and high-volume transfer for demanding Australian municipal drainage cycles.

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 maintains an unobstructed discharge path for debris, reducing wear during continuous operation. The two-channel configuration ensures stable pumping characteristics while preventing clogging during intensive Aussie site runoff management.

Construction features high-grade gray cast iron for principal wetted parts, supported by a 420 stainless steel shaft and Insulation Class F motor. Sealing integrity 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, ensuring the motor remains dry in Australian waters.

FEATURES

• Heavy-duty gray cast iron build ensures structural integrity for large-scale Australian municipal dewatering.
• Shrouded two-channel impeller design facilitates 76.2 mm solids handling while reducing hydraulic wear.
• Large-volume 200 mm discharge bore achieves flow rates up to 9375 L/Min for intensive site drainage.
• Double-face mechanical seal with silicon carbide lower faces offers reliable protection against ingress.
• Tsurumi's Oil Lifter technology keeps the mechanical seal faces lubricated even if the oil volume is low.
• Miniature thermal protectors embedded in the windings directly cut the circuit during excessive heat buildup.
• Integrated leakage sensor electrode monitors water ingress into the oil chamber to protect the motor.
• Star-Delta starting method reduces current surge during activation for stable Aussie industrial power grids.
