Grundfos SL1.110.200.185.4.52M.N.51D.A.T Cast Iron 4-Pole Wastewater Pump for Raw Water with S-Tube Impeller

Forged completely from highly durable, premium cast iron, the SL1.110.200.185.4.52M.N.51D.A.T secures exceptional physical resistance against highly aggressive submersed wear. Incorporating a massive 200 mm inlet alongside a huge 200 mm outlet, this colossal submersible wastewater pump guarantees long-term structural integrity for intensive municipal water treatment plants and raw water intake stations. Operating dependably within flooded pits, the asset manages severe raw fluid surges seamlessly without ever compromising the broader subterranean network.

Safely buried at the core of this immensely thick metallic housing lies a precision-cast, perfectly balanced S-Tube impeller securely governed to maintain an exact 110 mm free passage. This remarkably massive internal volumetric clearance proves absolutely critical for capturing and seamlessly relocating thick, solid-heavy municipal sewage without any mechanical stalling. By neutralizing dense blockage risks at the primary fluid transfer layer, the continuous pressurized circulation loop effectively spares public utility facilities from disastrous emergency overflow events.

Supplying the tremendous kinetic force necessary for this operation is a highly efficient 18.5 kW continuous-duty Grundfos 4-pole motor wired directly into a commercial 415v three-phase grid. This perfectly balanced electrical assembly effortlessly outputs an impressive maximum head of approximately 21 m, constantly accompanied by extreme volumetric pumping capacities peaking at an enormous 7500 L/Min. The meticulously structured interior fluid velocity pathways harness this raw energy, manifesting profound internal thermodynamic stability and incredibly minimal vibration.

Permanently solidifying its protective commercial engineering profile, the robust system securely houses highly sensitive internal moisture sensors and active motor-protection thermistors natively within the main core. These incredibly reactive monitoring components constantly trace the fully sealed interior motor cavity, building an impenetrable defensive wall against sudden submersed fluid breaches or extremely dangerous thermal heat overloads. This absolute tracking mechanism grants facility site engineers total peace of mind while significantly lowering scheduled maintenance.

Features

• Utilizes a highly advanced external cable entry connector plug that safely allows the heavy-duty fifteen-meter waterproof cord to be completely disconnected without removing the massive upper motor casing.
• Features a remarkably accessible double shaft seal configured inside a dedicated, modular cartridge design, actively permitting rapid primary maintenance interventions without requiring heavy specialized lifting equipment.
• Manufactured with a highly durable secondary shaft seal built heavily from an ultra-tough silicon carbide and carbon friction material configuration to successfully isolate and strictly protect the sensitive internal core.
• Built using incredibly thick, premium EN 1561 EN-GJL-250 cast iron across the main primary pump housing and exterior protective motor shell to physically ensure absolute maximum mechanical resilience in permanently flooded environments.
• Designed to seamlessly process immense raw fluid volumetric loads continuously at incredibly dense temperature ranges actively spanning from exactly ten to forty degrees Celsius within absolutely permanent deep municipal networks.
• Engineered to safely endure a thoroughly tested maximum continuous underwater installation depth of exactly twenty meters while perfectly preserving an absolute structural eight bar internal casing operating pressure tolerance.
