Grundfos SL1.110.200.220.4.52M.N.51D.A.T Cast Iron 4-Pole Wastewater Pump for Stations with S-Tube Impeller

Encased in incredibly thick EN 1561 EN-GJL-250 cast iron, the SL1.110.200.220.4.52M.N.51D.A.T provides profound defense against aggressive submersed wear. Utilizing a massive 200 mm inlet alongside a matching 200 mm outlet, this submersible pump secures structural integrity for extensive municipal water treatment networks. Deployed deep within flooded pits, the system manages overwhelming raw sewage surges effortlessly.

Housed at the core of this durable metallic exterior lies a specialized S-Tube impeller engineered to strictly enforce an absolute 110 mm free passage. This expansive internal clearance is essential for seamlessly discharging solid-heavy sludge without mechanical hesitation. By neutralizing blockage threats at the fluid intake layer, the pressurized loop spares processing plants from emergency overflows.

Harnessing extreme kinetic power, the unit relies on a highly efficient 22 kW continuous-duty Grundfos 4-pole motor wired into a commercial 415v three-phase grid. This calibrated drive outputs an impressive maximum head of approximately 23 m, accompanied by extreme pumping capacities peaking at an enormous 8340 L/Min. Intelligently mapped fluid pathways effectively stabilize the overwhelming thermodynamic heat generated.

Cementing its extremely reliable commercial profile, the robust framework incorporates active internal moisture sensors alongside proactive motor-protection thermistors. These highly reactive tracking systems continuously audit the fully sealed motor cavity, establishing a permanent defensive barrier against submersed liquid breaches or severe thermal overloads, greatly extending the core operational lifespan.

Features

• Integrates an advanced double shaft seal constructed in an exclusive, 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 exactly 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 exactly ten up to forty degrees Celsius within utterly unyielding municipal processing plant setups.
