Grundfos SL1.110.200.130.4.52M.N.51D.A.T Cast Iron 4-Pole Sewage Pump for Buildings with S-Tube Impeller

Optimized internal fluid velocity pathways allow the SL1.110.200.130.4.52M.N.51D.A.T to project exceptional hydraulic stability when placed under extreme subsurface loading. Designed around an enormous 200 mm outlet and matching 200 mm inlet, this massive submersible wastewater pump thrives moving tremendous volumes of raw sewage continuously. Handling extreme subterranean transfer demands, the asset effectively establishes an unyielding baseline for vital municipal wastewater treatment facilities.

Governing the heavily fortified cast iron fluid chamber is an advanced S-Tube impeller precisely calibrated to guarantee an incredible 110 mm free passage. This vastly expanded spatial tolerance actively permits dense commercial sludge and large abrasive fibrous debris to pass completely unrestricted. By actively preventing suspended heavy solid waste from accumulating inside the volute, the extensive extraction infrastructure continuously maintains perfect directional flow purity across the entire pressurized network.

Commanding this intense fluid motion is an exceptionally durable 13 kW continuous-duty Grundfos 4-pole motor drawing cleanly from a 415v three-phase grid. This incredibly robust drive configuration reliably pushes a maximum head of approximately 16 m alongside a vast 6180 L/Min peak flow rate. The intelligently integrated mechanical framework absorbs and smoothly dissipates extreme thermodynamic heat loads across its rugged iron exterior, effectively preventing the drive assembly from stalling out under heavy environmental duress.

Proactively guarding against catastrophic submersed mechanical failure, the robust core framework utilizes integrated internal moisture switches and advanced motor-protection thermistors. These built-in autonomous safety layers relentlessly monitor the completely sealed cavity climate, executing an immediate reactive defense protocol if unwanted hazardous liquids breach the casing boundaries. This continuous native oversight radically extends the functional deployment lifespan of the entire industrial pumping unit.

Features
