Submersible pump Tsurumi C Series
Tsurumi Submersible Wastewater Pump C Series. Power: 0.75 – 15 kW. The C Series is a submersible cutting impeller pump designed for raw wastewater treatment. It features a cutting mechanism to shred fibrous materials into small pieces. Below are the detailed product modules of the Tsurumi C Series submersible pump.
Tsurumi C-series pumps are heavy-duty, submersible cutter pumps for sewage and wastewater, which are made of castings and equipped with cutting mechanism. Featuring a combination of impeller vane with brazed sintered tungsten carbide alloy edge and a suction cover of serrated shape, the C-series pumps enable smooth pumping, while cutting solid and fibrous matter during suction. These pumps have been used to drain sewage and wastewater from buildings and kitchens, and to transfer sewage and wastewater in water treatment facilities of factories and commercial complexes.
The C-series comes in a wide product lineup, covering discharge bore diameters of 50 to 200 mm and motor outputs of 0.75 to 37 kW. Among the C-series pumps, “CR” models are available as highly durable cutter pumps, whose impeller and suction cover are made of high-chromium cast iron as a standard feature.
All models of the C-series can be used in combination with a guide rail fitting device that enables easy installation and maintenance. In addition, a new model of dry pit type is optionally available. The dry pit type pump can be installed indoors, and outside a tank. With Tsurumi’s original specifications for dry pit, the dry pit pump delivers the performance of conventional submersible pumps in a variety of sites.
These pumps integrate original technologies that Tsurumi has researched and proven in the field over many years, such as anti-wicking cable, dual inside mechanical seals with silicon carbide face and Oil Lifter, etc.
Furthermore, durability and wear resistance have been thoroughly considered in their design, so these pumps enable continuous duty over long periods of time.
Tsurumi products are designed to provide excellent durability and sound quality, thus contributing to the stable operation of facilities and enabling a considerable reduction in maintenance cost.

Construction of Tsurumi C Series Pumps
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 control panel to shut the power supply.
Dual 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.
Oil 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.
Leakage Sensor
Float Type (80C215-CR and 100C222-CR)
Electrode Type (200C437-CR)
Detects flooding into the incursion water storage chamber and oil chamber that may occur in a worst case scenario. When flooding is detected, signals are sent to operate the indicator lamps through the external control panel.
Oil Seal
Used as a “Dust Seal,” it protects the mechanical seal from abrasive particles.
Seal Pressure Relief Port
(5.5kW and above of 2-pole, and 200C437-CR)
Protects the mechanical seal from pump pressure. It also protects the seal face by discharging wear particles.
Air 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.
