TSURUMI PUMP

CZSERIES

The CZ-series is a submersible smashing cutter pump specially designed for pumping sewage and wastewater containing various solid waste including fibrous materials. A unique design of heart-shaped suction cover equipped with a sharp-edged stationary blade along with an improved semi-open channel impeller having two sharp-edged vanes incorporates the scissor mechanism. This innovative scissor-like mechanism remarkably enhances the solid handling capabilities. It prevents pump clogging through crushing and shredding of solid objects.
In addition to that, the extended rotating guide equipped on impeller prevents the retention of solid waste at the central part of the impeller, thereby providing a smooth pumping operation.

FEATURES

POINT01 Heart-Shaped Stationary
Suction Blade
Extremely sharp blade is provided on the suction cover that crushes and shreds any solid with the help of rotating leading blade for better solid handling.
POINT03 Extended
Rotating Guide
The extended rotating guide prevents the solids from accumulating at the low-pressure suction region at the center of the impeller, which is highly-prone to clogging. The extended rotating guide is designed to guide the wastes into the channel towards the sharp-edged blades and away from the center of the impeller, vastly improving the reliability against clogging.
POINT02 Rotating
Leading Blade
The high-efficiency open-type two-vane impeller is equipped with a sharp-edged leading blade, which brings solid matter towards the stationary suction blade at an optimum angle. These two blades work together, acting like scissors, to efficiently cut and shred any solids into pieces allowing them to pass through smoothly.

STRUCTURE

  • 1 - 31 - 4
  • 4 - 75 - 8
1Anti-wicking Cable Entry
Prevents water incursion due to capillary action should the cable sheath be damaged or the end of cablesubmerged.
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.
2Motor 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 control panel to shut the power supply.
3Dual Inside Mechanical Seals with
Silicon Carbide Faces
Isolated in the oil chamber where a clean, non-corrosive and abrasion-free lubricating environment is maintained. Compared with the water-cooled outside mechanical seal, it reduces the risk of failure caused by dry-heating and adhering matter. The silicon carbide provides 5 times higher corrosion, wear and heat resistance than the tungsten carbide. Rubber parts of the upper and lower fixing rings are made of NBR or FPM (FKM), which provides higher resistance to heat and chemicals.
4Oil Lifter
Provides lubrication and cooling of the seal faces down to 1/3 of normal oil level, thus maintaining a stable shaft sealing effect and prolonging seal life longer. The Oil Lifter is Tsurumi original design.Watch Movie

5Oil Seal
Used as a “Dust Seal”, it protects the mechanical seal from abrasive particles.
6Back Pull-out Design
Enables the motor to be separated from the pump unit with the impeller attached, by removing the bolts between the oil casing and the pump casing. This design facilitates maintenance and inspection of the principal parts of the pump.
7Air Release Valve
Fitted on the pump casing to prevent the air lock. When air flows through the valve, the ball stays at the bottom, but when the pumped water starts to flow, the ball closes the outlet because of its buoyancy.
8Impeller & Heart-shaped
Suction Cover
Crushing and shredding performance beyond that of conventional cutter pumps
Tsurumi’s original Heart-shaped Suction Cover is a unique design that improves the conventional Tsurumi cutter pumps by powerfully crushing and finely cutting solid and fibrous matters. Coupled with the new high efficiency two blade hydraulic impellers, CZ-series has greatly enhanced the pump performance while improving the cutting functions. Furthermore, the extended rotating guide on the impeller prevents any waste material clogging in the central part of the impeller and facilitates smooth transfer of waste. Tsurumi is proud to launch the reliable and innovative upgraded cutter pumps, CZ-series.
