Product Overview
Reducing long-term operating costs while maximizing autonomous safety, the SL1.95.150.220.4.52H.N.51D.A.T delivers absolute reliability to intensive municipal zones. Outfitted with a resilient 150 mm outlet and matched 150 mm inlet, this premium asset handles continuous raw water extraction. Built to survive aggressive flooded environments, the pump removes hazardous sewage rapidly.
The massive exterior casting houses an intelligently structured S-Tube impeller that dictates a 95 mm free passage. This expanded spatial clearance actively combats the severe blockage risks that traditionally cripple solid-heavy sewage setups. Municipal engineers can confidently rely on this sealed system to continuously process thick, fibrous waste streams without chaotic downtime.
Kinetic energy is channeled through a refined 22 kW continuous-duty Grundfos motor linked to a 415v three-phase grid. This advanced 4-pole drive generates a maximum head of approximately 29 m alongside a staggering 4986 L/Min continuous flow limit. The resulting operational stability sustains remarkably low mechanical vibration.
Removing dependency on fragile external sensor arrays, the pump natively deploys responsive moisture switches and motor-protection thermistors. These reactive systems continually verify the integrity of the sealed motor cavity, instantly alerting operators if boundaries are compromised.
Features
- Integrates a state-of-the-art external cable entry plug that allows the fifteen-meter electrical line to be detached safely and efficiently without opening the main motor housing.
- Features an innovative double shaft seal configured inside a dedicated cartridge assembly, minimizing critical service downtime during rigorous scheduled municipal maintenance.
- Utilizes a high-strength secondary shaft sealing ring built from a resilient silicon carbide and carbon friction composition to actively block internal cavity contamination.
- Manufactured with a massively thick primary casting built entirely from EN 1561 EN-GJL-250 iron, delivering maximum environmental durability across continuous flooded operations.
- Engineered to safely function continuously through heavy-density liquid temperatures between ten and forty degrees Celsius within permanent subterranean pumping stations.
- Designed to safely process intense deep fluid extraction at a maximum installation depth of twenty meters while preserving an exact eight bar operating pressure boundary.
