Product Overview
Commercial wastewater plants and large underground car parks generate heavy fluid loads requiring unyielding extraction. The SL1.85.100.110.4.52H.N.51D.A.T tackles these severe demands via its 150 mm inlet and 100 mm outlet. This submersible configuration removes raw sewage rapidly, shielding valuable municipal infrastructure from flooding.
A central mechanical advantage rests in its cast iron fluid chamber containing a balanced S-Tube impeller. By scaling the internal clearance to permit an 85 mm free passage, the pump prevents thick solid-laden waste from accumulating. This capability is absolutely crucial for preventing devastating system bottlenecks across the grid.
Powering this extreme internal velocity is a durable 11 kW Grundfos 4-pole motor running on a 415v three-phase grid. This assembly converts electrical energy into heavy fluid motion, reaching a maximum head of approximately 21 m and an immense 4986 L/Min flow. Such raw power builds exceptional thermodynamic stability across long cycles.
Protecting this asset against submersed threats, the pump incorporates vital moisture sensors and motor-protection thermistors directly into its core. These defensive barriers track the sealed casing for leaks or thermal overloading, proactively isolating the system before severe mechanical failure disrupts the primary distribution loop.
Features
- Features an advanced double shaft seal constructed in a highly modular cartridge format to permit safe fluid replacements without requiring specialized heavy tools.
- Incorporates a dedicated quick-release cable entry connector that actively allows the main power cord to be fully disconnected without removing the upper motor cover.
- Constructed using an EN 1561 EN-GJL-250 cast iron motor casing and pump volute to assure maximum mechanical resilience and passive heat dissipation in submersed settings.
- Utilizes a profoundly durable secondary shaft seal constructed from a tough silicon carbide and carbon friction material combination to shield the internal core.
- Rated to safely operate at a maximum continuous installation depth of twenty meters while preserving an absolute eight bar maximum internal operating pressure tolerance.
- Engineered to easily endure extreme continuous submerged fluid temperatures ranging from ten up to forty degrees Celsius within unyielding municipal processing setups.

In civil infrastructure drainage facilities, what maximum fluid volume is discharged during heavy flows?
Municipal collection wet wells utilize Grundfos SL1.85.100.110.4.52H.N.51D.A.T to displace wastewater at a peak rate of 4986 L/Min.
In civil infrastructure drainage facilities, what maximum vertical elevation is achieved by this pump?
Deep collection wet wells operate with SL1.85.100.110.4.52H.N.51D.A.T attaining a maximum hydraulic lift of 21 m.
What are the electrical power parameters, line voltage connection, and running current of this motor?
Submerged electrical specs for SL1-85-100-110-4-52H-N-51D-A-T feature a 11 kW motor connected to a three-phase 415 V feed drawing 23 Amps.
What spherical through-let clearance protects this municipal pump from ragging and solids blockage?
Large wastewater solids traverse SL1 85 100 110 4 52H N 51D A T freely thanks to an expansive 85 mm spherical through-let designed into the S-tube channel.
What auto-coupling assembly connects this submerged unit firmly to permanent pit piping?
Routine servicing is simplified with SL1/85/100/110/4/52H/N/51D/A/T, which docks onto guide rail auto-coupling bases for rapid hoist extraction.
