Tsurumi 80C211-CR Gray Cast Iron Dual Seal Submersible Cutter Pump for Sewage Transfer with Semi-open Impeller

The Tsurumi 80C211-CR is a formidable submersible pump tailored for demanding sewage transfer applications in municipal and commercial settings. It is specifically designed to function flawlessly in submerged environments where raw sewage and heavy wastewater require continuous, reliable processing. The structural integrity of this pump ensures that it can withstand the physical stresses associated with high-volume fluid management without faltering.

Operating via a Star-Delta starting method, this unit is powered by an 11 kW motor connected to a 415 V three-phase supply. It draws a rated current of 22.8 Amps, enabling it to deliver a substantial maximum flow of 1200 L/Min. Furthermore, it achieves an impressive maximum head of 47 m, providing the necessary hydraulic force to transport wastewater over long distances and significant elevations.

A sophisticated cutting mechanism lies at the heart of its fluid processing capabilities. The pump features a semi-open two-channel impeller equipped with a brazed sintered tungsten carbide alloy edge. This component works synergistically with a serrated suction cover to actively shred fibrous solids upon entry, facilitating smooth passage through the 80 mm discharge port and preventing operational blockages.

Constructed for maximum durability, the pump combines a gray cast iron casing with a high-chromium cast iron impeller and suction cover, suitable for liquid temperatures up to 40°C. The internal motor assembly is protected by dual inside silicon carbide mechanical seals within an oil chamber. A proprietary oil lifter maintains seal lubrication, and an anti-wicking cable entry provides a robust defense against water intrusion.

FEATURES

• Semi-open two-channel impeller with a tungsten carbide alloy edge efficiently shreds incoming fibrous solids.
• High-chromium cast iron construction of critical wear parts significantly extends the pump's operational lifespan.
• Dual inside mechanical seals with silicon carbide faces offer protection for the motor shaft.
• Proprietary oil lifter ensures consistent and reliable lubrication to the upper seal faces.
• Anti-wicking cable entry mechanism effectively blocks water from entering the motor via capillary action.
• Star-Delta starting method reduces inrush current during motor startup for smoother electrical integration.
• Heavy-duty gray cast iron casing provides a robust enclosure for continuous submerged operation.
