Product Overview
Intelligently mapped fluid velocity paths allow the SL1.95.150.200.4.52H.N.51D.A.T to project hydraulic stability under extreme loads. Designed around a 150 mm outlet and matching 150 mm inlet, this high-volume submersible pump is optimized for intense industrial sectors moving raw sewage. It securely establishes a highly reliable transfer baseline for essential municipal facilities.
Governing the fluid chamber is an advanced S-Tube impeller calibrated to ensure a 95 mm free passage. This spacious structural clearance permits dense commercial sludge and fibrous debris to pass unrestricted. By actively preventing suspended heavy solids from accumulating inside the volute, the extraction infrastructure maintains perfect flow purity.
Commanding this fluid motion is a durable 20 kW continuous-duty Grundfos 4-pole motor. Operating strictly on a 415v three-phase grid, this powerhouse reliably pushes a maximum head of approximately 27 m alongside a vast 4986 L/Min peak flow rate. The configuration smoothly dissipates thermodynamic heat loads across the rugged iron exterior.
Proactively shielding against mechanical failure, the core framework relies on integrated moisture switches and motor-protection thermistors. These internal safety layers relentlessly monitor the sealed cavity climate, executing an immediate reactive defense protocol if unwanted liquids breach the casing boundaries.
Features
- Equipped with a modular quick release cable entry plug that effectively allows the heavy-duty fifteen-meter power cord to be securely detached without unbolting the motor top.
- Incorporates a highly service-friendly double shaft seal structured in an exclusive cartridge layout to permit rapid field replacements without specialized mechanical tools.
- Constructed with a primary pump volute and upper motor casing cast completely from EN 1561 EN-GJL-250 grade iron for optimal submerged environmental resilience.
- Engineered with a highly reliable secondary shaft seal utilizing an advanced silicon carbide and carbon mechanical friction material block to permanently stop moisture leaks.
- Fully rated to handle relentless extraction operations in dense liquid temperature ranges spanning from ten to forty degrees Celsius within completely flooded installations.
- Configured to handle extreme fluid transfers securely at a maximum installation depth of twenty meters while safely maintaining a strict eight bar maximum operating pressure.

Within deep collection wet wells, what peak volumetric flow rate is displaced during heavy pumping cycles?
Across heavy drainage cycles, Grundfos SL1.95.150.200.4.52H.N.51D.A.T evacuates wastewater at a maximum rate of 4986 L/Min.
In centralized municipal collection terminals, what peak vertical discharge elevation is maintained?
Centralized lift vaults operate with SL1.95.150.200.4.52H.N.51D.A.T maintaining a vertical discharge elevation of 27 m.
Which motor kilowatt output, line voltage feed, and operational current draw support this pump?
Electrical parameters for SL1-95-150-200-4-52H-N-51D-A-T specify a 20 kW motor operating from a three-phase 415 V power line at 41 Amps.
How does the precision S-tube profile maintain hydraulic efficiency during heavy solids transit?
Hydraulic contours of the S-tube runner in SL1 95 150 200 4 52H N 51D A T maintain an unobstructed corridor that accommodates solid waste up to 95 mm.
Which auto-coupling system connects this large submersible unit to permanent discharge piping?
Submerged in wet wells, SL1/95/150/200/4/52H/N/51D/A/T locks securely onto guide rail auto-coupling pedestals to establish a tight discharge seal.
