DFBS415 Heavy-Duty Submersible Slurry Pump - 200 mm Outlet
Model: DFBS415
DFBS415 heavy-duty submersible slurry pump with 15 kW motor and 200 mm discharge. Catalog duty: 200 m³/h at 16 m; catalog maximum reference values reach 372 m³/h and 22 m.
TECHNICAL DATA
Specifications, performance and construction
Confirm the final operating point, materials, motor and connection standard before ordering.
DFBS415 product overview
Four-pole heavy-duty submersible slurry pump with high-chromium-alloy hydraulic parts and bottom agitator for high-flow muddy water, sludge and bentonite transfer.
This page is matched to the official DFIN DFBZ / DFBD series catalog. The listed duty values identify the exact 200 mm configuration; final selection must be checked against the required system curve, liquid and installation method.

Typical applications
- High-flow mine and quarry slurry
- Bentonite and foundation slurry
- Sewage-treatment sludge
- Civil-engineering muddy-water drainage
Selection and ordering guide
- Provide the required flow and total dynamic head, including pipe and fitting losses.
- Describe the liquid, solids size, solids concentration, abrasiveness and temperature.
- Confirm sump depth, installation method, discharge connection and required cable length.
- Confirm voltage, frequency, control cabinet, level-control and intelligent-protection requirements.
- For slurry service, provide particle distribution and settling tendency so the agitator and wear materials can be verified.
Installation and service notes
Keep the pump within the minimum operating-water level shown in the catalog, verify rotation before continuous operation, and never lift the pump by its cable. Inspect the strainer, impeller, inlet plate or agitator, mechanical seals and cable entry at planned service intervals. Isolate power and pressure before maintenance.
