Product Overview
High-volume fluid optimization in municipal wastewater systems is achieved by the heavy-duty structural foundation of the Grundfos SL.150.100.4.52H.N.51D.A.T. This submersible pump addresses the requirements of municipal wastewater transport where contaminated liquids are present. The system handles effluent transfer at temperatures up to 40°C in subsurface collection pits. Maintaining operational flow behavior in permanent submerged installations is essential for infrastructure protection and facility maintenance.
Hydraulic performance is provided by a 10 kW four-pole motor on a 415v three-phase supply, generating a maximum flow of 6,000 L/min. This model achieves a maximum total head of 21.1 m. Operating with a rated current of 21 Amps, the unit maintains consistent torque and circulation stability during continuous duty cycles. Rapid evacuation is achieved through the DN 150 discharge port, while the 15-metre power cable provides a secure electrical connection for submerged installations.
Internal centrifugal design utilizes a high-efficiency Open S-Tube impeller to facilitate the passage of solids in suspension. This configuration handles wastewater, maintaining volumetric efficiency throughout prolonged service cycles in municipal networks. By utilizing the s-tube principle, the unit minimizes internal friction and vibration to protect the rotating assembly during high-volume discharge. The impeller setup is intended for municipal wastewater applications in collection and transfer systems.
Mechanical integrity is reinforced by a heavy-duty cast iron body and motor shell with an IP68 protection rating for depths up to 20 m. Motor insulation is anchored by a shielded assembly with a double mechanical shaft seal arrangement in an oil bath. This model features integrated moisture sensors and thermistors for proactive monitoring and early fault detection in submerged conditions. The architectural casting features DN 150 inlet and outlet connections for high-capacity integration into standard wastewater infrastructure.
Features
- Open S-Tube impeller configuration facilitates high-efficiency solids handling and prevents internal blockages in high-volume networks.
- Heavy-duty cast iron construction of the housing and motor shell provides the structural durability needed for deep pit installations.
- DN 150 inlet and DN 150 outlet connections allow for high-capacity liquid transfer through standard pipework.
- Double mechanical shaft seal in an oil bath with silicon carbide faces ensures the motor remains shielded from liquid ingress.
- IP68 enclosure rating confirms the unit is suitable for permanent immersion in wastewater collection pits up to 20 metres.
- Integrated thermistors and moisture sensors enable real-time monitoring to protect the electrical assembly.
- Four-pole motor operating at 1,482 rpm provides the starting torque required for high-volume wastewater collection systems.

Where high fluid throughput is critical, what peak volumetric displacement does this unit provide?
Outflow capacity peaks at 6000 L/Min each minute when deploying Grundfos SL.150.100.4.52H.N.51D.A.T.
When discharging into elevated gravity mains, what peak elevation does this pump attain?
Municipal lift networks deploy SL.150.100.4.52H.N.51D.A.T to overcome static head requirements up to 21.1 m.
Across station electrical networks, which electrical drive parameters, supply voltage parameters, and running current run this motor?
Engineered power specifications for SL-150-100-4-52H-N-51D-A-T define a 10 kW motor operating on a three-phase 415 V supply at 21 Amps.
Maintaining steady line velocity, how does the precision hydraulic profile maintain efficiency during solids transit?
Preventing solids accumulation, SL 150 100 4 52H N 51D A T maintains a 100 mm spherical through-let through its Open S-tube profile.
Under submerged operating conditions, which guide rail auto-coupling configuration supports secure submerged wet well docking?
The discharge elbow in the sump docks with SL/150/100/4/52H/N/51D/A/T via an auto-coupling pedestal that forms a leak-free pressure seal.
