Grundfos SL1.110.200.170.4.52M.N.51D.A.T Cast Iron 4-Pole Sewage Pump for Flats with S-Tube Impeller

Massive subterranean commercial networks constantly generate exceptionally heavy fluid loads requiring unyielding extraction channels. The SL1.110.200.170.4.52M.N.51D.A.T tackles these volume demands directly by deploying an enormous 200 mm outlet alongside its 200 mm inlet. This huge submersible asset rapidly purges raw sewage from deeply flooded basins, establishing an invincible protective barrier against devastating infrastructure flooding.

A primary engineering advantage exists within the premium cast iron fluid chamber, which securely surrounds a perfectly balanced S-Tube impeller. By scaling the rotational tolerance to seamlessly permit a 110 mm free passage, the pump actively prevents heavily solid-laden sludge and organic debris from accumulating inside the main volute. This circulatory capability proves vital for permanently eliminating disastrous systemic bottlenecks across demanding public complexes.

Generating extreme internal fluid velocity is a highly durable 17 kW Grundfos 4-pole motor consistently drawing power from a commercial 415v three-phase grid. The exceptionally robust drive assembly successfully converts electrical energy into overwhelming fluid motion, reliably reaching a maximum head of approximately 19 m and an immense 7500 L/Min transfer rate. This refined heavy-duty power translates into phenomenal thermodynamic stability, preserving internal drive integrity throughout transfer cycles.

Actively protecting the commercial facility investment against unpredictable submersed threats, the system incorporates vital moisture detection sensors and active motor-protection thermistors directly into its sealed deep core. These internal defensive barriers continuously track the motor casing climate for hazardous liquid leaks or sudden thermal overloading. By proactively isolating the system before mechanical overheating can propagate, the heavy pump successfully prevents incredibly costly pipeline disruptions.

Features

• Integrates an advanced double shaft seal constructed in a highly modular cartridge format to uniquely permit safe fluid sealing replacements without requiring specialized heavy tools.
• Incorporates a dedicated quick-release cable entry connector that actively allows the main fifteen-meter waterproof power cord to be fully disconnected without removing the heavy upper motor cover.
• Constructed using an incredibly thick EN 1561 EN-GJL-250 cast iron motor casing and primary pump volute to assure maximum mechanical resilience and passive heat dissipation in submersed settings.
• Utilizes a profoundly durable secondary shaft seal constructed specifically from a tough silicon carbide and carbon friction material combination to effectively shield the internal working core.
• Rated to flawlessly operate at a maximum continuous deep installation depth of twenty meters while firmly preserving an absolute eight bar maximum internal structural operating pressure tolerance.
• Engineered to easily endure extreme continuous submerged liquid temperatures constantly ranging from ten up to forty degrees Celsius within utterly unyielding municipal processing plant setups.
