Tsurumi 100BZ411 Gray Cast Iron Wastewater Pump for Manholes with Single-Channel Impeller

Sump emptying and municipal sewage management in Australian commercial facilities require a high-capacity pump with superior mechanical durability. This manual submersible unit is configured for handling wastewater and industrial sewage in large-scale sumps without frequent maintenance. Its robust gray cast iron metallurgy and channel impeller design ensure consistent performance in Aussie environments where dependable operation is critical.

Driven by an 11 kW / 415v three-phase motor, the system delivers a maximum flow capacity of up to approximately 2820 L/Min and achieves a peak head of up to approximately 20.8 m. The induction motor is continuous-duty rated and utilizes a Star-Delta starting method to manage the 22.8 Amps current draw efficiently. This configuration ensures stable pumping performance for commercial sewage drainage across diverse Australian sites.

The hydraulic configuration utilizes a shrouded single-channel impeller manufactured from gray cast iron to enable 80 mm solids passage. This design provides a wide flow passage that allows debris to move through the pump without obstruction, maintaining stable pumping characteristics during intensive Aussie site water management duties. The wide internal passage supports continuous solids transport during sustained operation.

Mechanical integrity is supported by a 420 stainless steel shaft and Insulation Class F motor, with dual mechanical seals isolated in an oil chamber featuring an Oil Lifter. Protection is enhanced by miniature thermal protectors embedded in each motor winding and an anti-wicking cable entry block. This configuration safeguards the dry-type motor from moisture ingress and thermal overload during intensive Australian dewatering cycles.

FEATURES

• Gray cast iron build provides the structural integrity required for intensive Australian sump emptying tasks.
• Shrouded single-channel impeller configuration facilitates the displacement of solids up to 80 mm without clogging.
• High-capacity 11 kW motor with Star-Delta starting ensures reduced starting current for large Aussie sumps.
• Double-face mechanical seal with silicon carbide faces provides reliable protection against abrasive particles.
• Proprietary 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 excessive heat buildup.
• Watertight cable entry with an anti-wicking block prevents moisture from entering the motor through capillary action.
• Large 100 mm discharge bore supports flow rates up to 2820 L/Min for rapid industrial wastewater drainage.
