This professional cast iron submersible drainage pump is developed for heavy-duty industrial and municipal wastewater plants. It features a wide discharge bore and a high-flow hydraulic casing designed to transport rainwater and light sewage from deep collection sumps. The pump is suited for wastewater measuring tanks; municipal drainage; and rainwater collection systems.
The motor is a 5.5 kW three-phase 415 V dry-type induction motor drawing a rated current of 11.4 Amps. Traced from the official 50Hz manufacturer performance curves; this pump delivers a maximum head of approximately 33 m and a maximum capacity of approximately 1338 L/Min. The starting method is direct on line; with star-delta starting available on request.
Its mechanical build features a cast iron semi-open multi-vane impeller that allows free passage of solids up to 15mm in diameter. Sealing is managed by dual-face mechanical seals inside an oil chamber with ceramic-to-carbon upper faces and silicon carbide-to-silicon carbide lower faces. A seal pressure relief port protects the mechanical seal from high pressure.
Windings are protected by a circle thermal protector inside the watertight housing that shuts the circuit when overcurrent or excess heat is detected. The power cable is an 8-meter chloroprene rubber cabtyre cable with Tsurumi's anti-wicking block. Sump installation and maintenance are made efficient using the optional guide rail set TOS80SF25.5.
