Product Overview
Severe fluid surges require unyielding extraction infrastructure to prevent overflow. The SL1.110.200.200.4.52M.N.51D.A.T tackles these extreme loads via an enormous 200 mm inlet paired with a 200 mm outlet. Operating within deeply flooded pits, this submersible pump rapidly clears raw sewage, effectively neutralizing bottleneck risks across municipal complexes.
Forged from thick EN 1561 EN-GJL-250 cast iron, the chamber securely houses an S-Tube impeller accurately calibrated to guarantee a massive 110 mm free passage. This expanded internal clearance effortlessly permits solid-laden sludge to pass without stalling. By permanently eliminating mechanical choke points, the circulation loop safely secures directional flow purity.
Generating immense kinetic force is a durable 20 kW Grundfos 4-pole motor drawing cleanly from a 415v three-phase grid. This assembly converts raw power into heavy fluid motion, reaching a maximum head of approximately 21 m and an incredible 8340 L/Min peak flow rate. Highly optimized interior pathways smoothly dissipate intense thermodynamic heat loads.
Guarding against submersed failures, the system incorporates moisture switches and active motor-protection thermistors directly into its core. These autonomous safety mechanisms relentlessly scan the sealed cavity, providing an immediate reactive defense if unwanted liquid breaches the primary casing boundaries.
Features
- Features a remarkably accessible double shaft seal configured inside a dedicated, modular cartridge design, actively permitting rapid primary maintenance interventions.
- Utilizes a highly advanced external cable entry connector plug that safely allows the heavy-duty fifteen-meter waterproof cord to be disconnected without unbolting the top.
- 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 resilience.
- Manufactured with a highly durable secondary shaft seal heavily built from an ultra-tough silicon carbide and carbon friction material configuration to protect the internal core.
- Designed to seamlessly process immense raw fluid volumetric loads continuously at dense temperature ranges actively spanning from exactly ten to forty degrees Celsius.
- Engineered to safely endure a thoroughly tested maximum continuous underwater installation depth of exactly twenty meters while maintaining a strict eight bar internal operating pressure.
