Tsurumi 50C2.75 Gray Cast Iron 2-pole Submersible Cutter Pump for Municipal Sewage with Semi-open Impeller

The Tsurumi 50C2.75 is designed to handle demanding municipal pumping environments where fibrous solids and heavy wastewater are prevalent. This unit operates effectively in submerged conditions, managing the continuous transfer of raw sewage and drainage from commercial complexes and water treatment facilities. The structural design accommodates the rigors of heavy-duty municipal applications, ensuring consistent liquid movement without frequent blockages.

Driven by a three-phase 415 V system, this model utilizes a 0.75 kW motor to achieve a maximum flow rate of 335 L/Min. The hydraulic performance peaks at a maximum head of 11.5 m, drawing a rated current of 2 Amps. These operating parameters allow the pump to maintain steady transfer balances during extended operational cycles in challenging wastewater environments.

Hydraulic efficiency is maintained through a specialized cutting mechanism that shreds fibrous materials upon entry. The semi-open single-channel impeller, equipped with a brazed sintered tungsten carbide alloy edge, works in tandem with a serrated suction cover. This configuration prevents clogging and ensures smooth circulation of solids-laden liquids through the 50 mm outlet.

Constructed with a gray cast iron casing and ductile cast iron suction cover, the pump is built for longevity in temperatures up to 40°C. Mechanical integrity is protected by dual inside silicon carbide mechanical seals housed in an oil chamber. The proprietary oil lifter provides reliable lubrication, while the anti-wicking cable entry prevents water ingress, safeguarding the internal motor components.
