Tsurumi 100CZ42.2 Cast Iron Submersible Cutter Pump for Fibrous Waste Handling with Semi-open Channel Impeller

This submersible smashing cutter pump is engineered specifically for municipal sewage processing and demanding industrial wastewater applications. It effectively manages liquids carrying heavy concentrations of fibrous waste such as plastic bags, wipes, and rope in temperatures up to 40°C. The unit thrives in municipal collection sumps and transfer stations where consistent, continuous-duty service is required for reliable wastewater management. The structural design supports both free-standing placement or integration into guide rail systems for convenient installation and maintenance access.

Operating with a 2.2 kW three-phase motor, the unit delivers a maximum flow rate of 1500 L/Min while reaching a total head of approximately 13.8 meters. The four-pole induction motor is rated for 415v operation at 50Hz and draws a precise rated current of 4.8 Amps. It maintains a stable synchronous speed of 1500 min?¹, providing the steady torque necessary for driving the integrated crushing mechanism through dense fluids. The Direct on Line starting method ensures immediate performance and efficient power delivery throughout the pumping cycle.

The hydraulic assembly uses a scissor-type crushing system that shreds fibrous waste before it enters the main discharge passage. By reducing oversized solids into smaller fragments, the system allows for reliable transfer through the hydraulic passage while minimizing the risk of internal blockages. The flow path is specifically designed to prevent solids from accumulating in the low-pressure suction region at the center of the impeller. This advanced geometry promotes continuous solids movement, ensuring the pump can effectively handle materials that would typically obstruct standard centrifugal designs.

Heavy-duty cast iron construction provides the structural integrity required for continuous wastewater service, while the rotating components are engineered to resist impact and abrasion. The internal sealing arrangement uses a dual mechanical system isolated in an oil chamber to protect motor components from liquid ingress. Integrated protection devices monitor for excessive heat buildup and overcurrent to prevent motor failure during challenging operational conditions. The electrical entry incorporates a specialized block that stops moisture from migrating through the power lead even if the cable sheath is damaged.

FEATURES

• High-efficiency semi-open channel impeller featuring twin sharp-edged vanes designed for aggressive solid reduction in wastewater streams.
• Stationary heart-shaped suction blade works against rotating vanes to provide a powerful, scissor-like shredding action.
• Extended rotating guide facilitates smooth fluid transition by directing solid waste away from the central impeller eye.
• Dual inside mechanical seals with Silicon Carbide faces provide five times higher resistance to abrasive wastewater particles.
• Tsurumi-original Oil Lifter maintains stable shaft sealing by lubricating faces even if oil levels drop below normal.
• Heavy-duty Gray Cast Iron JIS FC250 pump casing ensures a rigid structural foundation for continuous submerged service.
• Circle Thermal Protector monitors motor temperature and current to provide automated safety during electrical or thermal overload.
• Anti-wicking cable entry utilizes a molded block to stop water incursion through capillary action or damaged leads.
