Product Overview
Extreme surges present massive load challenges for municipal wastewater facilities handling raw sewage. The SL1.85.150.110.4.52H.N.51D.A.T tackles these volume demands utilizing a massive 150 mm outlet and 150 mm inlet configuration. This submersible pump reliably extracts contaminated fluids from flooded pits, establishing an unyielding baseline that defends public infrastructure.
Housed within a thick cast iron volute is a balanced S-Tube impeller that widens internal clearance to permit an 85 mm free passage. This scaling actively prevents thick municipal sludge and solid-heavy sewage from accumulating. Neutralizing these blockage risks successfully eliminates the devastating bottlenecks that constantly threaten sprawling commercial building networks and vast subterranean loops.
Supplying kinetic energy is a refined 11 kW Grundfos 4-pole motor drawing cleanly from a 415v three-phase grid. This robust assembly converts raw power into massive fluid motion, achieving a maximum head of approximately 21 m alongside a staggering 4986 L/Min flow capacity. Internal fluid velocity paths smoothly distribute intense thermodynamic heat loads across the metallic casing, preserving remarkably low operational vibration.
Dedicated to maximizing facility investment protection, the framework incorporates sensitive moisture switches and active motor-protection thermistors. These autonomous defensive barriers scan the sealed cavity to detect submersed breaches or sudden thermal overloads. This tracking grants site engineers immediate defensive oversight, saving large plants from costly emergency hardware replacements.
Features
- Integrates an advanced double shaft seal constructed in an easily accessible cartridge layout to permit rapid field replacements without requiring specialized heavy tools.
- Features a modular quick release cable entry connector that effectively allows the fifteen-meter power cord to be fully disconnected without removing the upper motor top.
- Constructed utilizing a primary pump volute and main motor casing cast entirely from EN 1561 EN-GJL-250 grade iron to guarantee maximum mechanical submersed resilience.
- Engineered with a highly durable secondary shaft seal utilizing an advanced silicon carbide and carbon mechanical friction material combination to actively block moisture.
- Fully rated to handle relentless extraction operations in dense liquid temperature ranges spanning from ten to forty degrees Celsius within permanent municipal networks.
- Configured to securely handle massive fluid transfers at a maximum installation depth of twenty meters while safely maintaining an exact eight bar operating pressure boundary.
