Tsurumi 200C437-CR Gray Cast Iron Submersible Cutter Pump for Abattoir Wastewater with Semi-open Impeller

Engineered for the most rigorous municipal pumping stations and extreme industrial wastewater management, the Tsurumi 200C437-CR provides unparalleled fluid handling capabilities. This massive submersible unit is designed to operate continuously in challenging environments where heavy effluents and fibrous solids are standard. Its robust construction ensures that immense volumes of raw sewage are processed and transported efficiently, minimizing the need for manual intervention.

This flagship model utilizes a 37 kW motor driven by a 415 V three-phase power source, drawing 72 Amps during operation. The pump is capable of generating a maximum head of approximately 28 m and delivering an extraordinary maximum flow rate of approximately 6540 L/Min. These substantial performance capabilities allow it to effectively manage massive fluid loads and overcome significant elevation changes in major infrastructure projects.

The core of its operational efficiency is a highly effective cutting mechanism designed for large-scale processing. A brazed sintered tungsten carbide alloy edge on the semi-open two-channel impeller works against a serrated suction cover to shred incoming debris. This active cutting process ensures that fibrous materials are reduced to manageable sizes, allowing for uninterrupted discharge through the massive 200 mm outlet.

Built to withstand extreme abrasive conditions, the pump incorporates a gray cast iron casing alongside a high-chromium cast iron impeller and suction cover, operating safely in liquids up to 40°C. Motor integrity is maintained by dual inside silicon carbide mechanical seals within an oil chamber. The proprietary oil lifter ensures consistent seal lubrication, and the anti-wicking cable entry protects against water infiltration.

FEATURES

• Brazed sintered tungsten carbide alloy edge provides aggressive shredding of fibrous municipal and industrial waste.
• High-chromium cast iron impeller and suction cover deliver excellent resistance to abrasive wear during continuous operation.
• Semi-open two-channel impeller design optimizes the continuous flow of processed solids and massive liquid volumes.
• Silicon carbide dual inside mechanical seals ensure reliable protection for the high-power motor shaft assembly.
• Integrated oil lifter maintains continuous lubrication to the mechanical seals under varying and extreme conditions.
• Anti-wicking cable entry effectively prevents internal motor damage caused by capillary water ingress.
• Star-Delta starting method reduces inrush current during motor startup for smoother electrical integration of the 37 kW motor.
