Tsurumi 100CZ45.5 Cast Iron Submersible Cutter Pump for Industrial Drainage with Semi-open Channel Impeller

This heavy-duty smashing cutter pump processes industrial drainage containing metal cans, plastic bottles, and large fibrous materials. It is engineered for continuous submerged service in municipal wastewater sumps and processing plant effluents up to 40°C. The unit manages varied waste streams without mechanical failure from blockages or solid accumulation. Compatibility with guide rail fitting systems allows for inspection and maintenance without the need to enter the collection pit for manual pump handling.

A 5.5 kW three-phase motor drives the unit at 415v, drawing a rated current of 12.0 Amps during high-torque operation. The 4-pole motor configuration supports a maximum flow rate of 2500 L/Min and a total head of approximately 21.1 meters. While Direct on Line is standard, Star-Delta starting is available upon request to manage system power demands during activation. Stable performance characteristics ensure the unit maintains sufficient pressure to move shredded solids through the 35 mm hydraulic passage.

The hydraulic assembly uses a scissor-type crushing system that shreds fibrous waste before it enters the discharge passage. Oversized solids are reduced into smaller fragments, allowing more reliable transfer while minimizing blockage during continuous operation. The advanced hydraulic geometry promotes continuous solids movement through the pump, ensuring efficient wastewater transfer in demanding applications. This design directs solids away from the central eye and toward the active cutting zone for consistent processing and removal.

Heavy-duty Gray Cast Iron JIS FC250 pump casing provides the high structural integrity required for industrial use and mechanical strength. Sealing is provided by dual inside mechanical seals with Silicon Carbide faces, which are cooled and lubricated within an oil chamber. The chloroprene rubber power cable features an anti-wicking block that improves long-term motor protection against moisture migration during continuous submerged operation. Motor safety is prioritized through integrated thermal sensors that monitor electrical stress to prevent internal damage.

FEATURES

• Two-vane semi-open channel impeller directs solid waste into the crushing zone for high-capacity shredding and transfer.
• Heart-shaped stationary suction blade creates a high-torque cutting mechanism capable of processing metal and plastic objects.
• Extended rotating guide eliminates central clogging risks by directing waste material away from the impeller center.
• Chloroprene rubber power cable provides high flexibility and superior resistance to chemical abrasion in industrial environments.
• Dual inside Silicon Carbide mechanical seals provide maximum protection against abrasive particles in submerged process pumping.
• Tsurumi Oil Lifter maintains a stable shaft seal by forcing lubricant to seal faces even at low levels.
• Automated Circle Thermal Protector interrupts the motor circuit to prevent failure during excessive heat or overcurrent conditions.
• Anti-wicking cable entry prevents moisture and vapor from infiltrating the motor housing through the electrical leads.
