Product catalog summary

Introduction
The Tsurumi CZ-series pumps are advanced submersible smashing cutter pumps designed for sewage and wastewater applications. These pumps feature a newly developed crushing mechanism that efficiently crushes and shreds solid materials into finer pieces, enhancing solid handling capabilities and preventing clogging.

Specifications and Design
The CZ-series pumps are constructed from durable materials such as ductile cast iron for the impeller and suction cover, and gray cast iron for the pump casing. The innovative design includes a heart-shaped stationary suction blade and a high-efficiency two-vane impeller with sharp edges, which work together to cut and shred solids effectively.

Key Features

Heart-shaped Suction Cover: Enhances the cutting and shredding performance beyond conventional cutter pumps.
Extended Rotating Guide: Prevents solid waste accumulation at the impeller's center, reducing clogging risks.
Dual Inside Mechanical Seals: Equipped with silicon carbide faces for superior corrosion, wear, and heat resistance.
Oil Lifter: Ensures lubrication and cooling of seal faces, prolonging seal life.
Anti-wicking Cable Entry: Prevents water incursion and condensation inside the motor housing.

Performance and Models
The CZ-series includes various models with motor outputs ranging from 2.2 kW to 15 kW, capable of handling solids up to 41 mm in size. The pumps are designed for continuous-duty operation and are compatible with guide rail fitting systems for easy installation and maintenance.

Options and Accessories

Seawater-resistant and high-temperature liquid versions available upon request.
Guide rail fitting system includes components like duckfoot bend, guide support, and lifting chain.
Float switches for liquid level sensing, including heavy-duty and economy types.

Conclusion
The Tsurumi CZ-series pumps represent a significant advancement in submersible pump technology, offering enhanced performance, reliability, and ease of maintenance. These pumps are ideal for challenging wastewater environments, providing efficient solid waste management and reduced maintenance costs.

Anti-wicking Cable Entry Prevents water incursion due to capillary action should the cable sheath be damaged or the end of cable submerged. Also prevents moist air from infiltrating the motor housing and condensation from forming inside the housing due to temperature differences between the housing and outside air. Motor Protector Circle Thermal Protector (7.5kW and below) Directly cuts the motor circuit if excessive heat builds up or overcurrent occurs in the motor. Miniature Thermal Protectors (11kW and above) React to excessive heat caused by dry-running. The bimetal strip opens to cause the...
