Product Overview
Featuring a profoundly durable structural casting layout, the SL1.75.100.150.2.52S.N.51D.A.T utilizes its robust 100 mm outlet to command intensive wastewater applications. Engineered entirely from heavy-duty cast iron, this exceptional commercial asset is designed to thrive within punishing municipal pumping stations and raw water intake facilities.
The core fluid architecture integrates an advanced S-Tube impeller that purposefully scales its internal clearances to accommodate an impressive 75 mm free passage, drastically reducing the potential for system blockages. This ensures uninterrupted processing of raw sewage and sludge across underground car parks and large-scale industrial complexes.
Delivering substantial fluid velocity, this continuous-duty system is driven by a high-efficiency 15 kW, 2-pole Grundfos motor capable of producing a maximum head of approximately 32 m and flows up to 3186 L/Min. Powered via a standard 415v three-phase supply, the hydraulic configuration ensures exceptional stability during demanding daily transfer loads.
To fortify this commercial investment against unexpected mechanical failures, the system integrates sophisticated moisture sensors and motor-protection thermistors. These automated safeguards monitor submersed conditions, allowing operators to minimize long-term maintenance expenditures and prevent downtime.
Features
- Equipped with a highly service-friendly double shaft seal structured in a unique cartridge layout to permit rapid field replacements without specialized tools.
- Integrates a modular cable entry connector configuration that allows the heavy-duty 15-meter power cord to be detached without unbolting the motor top.
- Constructed with a primary pump housing cast from EN 1561 EN-GJL-250 grade iron for maximum submerged environmental resilience and long-term durability.
- Engineered with a secondary shaft seal utilizing a robust silicon carbide and carbon mechanical friction material combination.
- Rated for continuous heavy-duty operations in liquid temperature ranges spanning from ten to forty degrees Celsius within fully submerged installations.
- Configured to handle a maximum installation depth of twenty meters while safely maintaining an eight bar operating pressure boundary.
