Supplier Part Number: SPX4150000
Pros and Cons:
+ Powerful 15 kW three-phase pump (400V) for sand and dirty water
+ Open free-flow impeller — insensitive to fibers and solids
+ Robust cast iron housing with chrome steel impeller — wear-resistant
+ Double mechanical shaft seal (SiC) and thermal protection
- Only as 400V three-phase — no 230V version
Professional heavy-duty dirty water submersible pump
The SPT 4150 is a heavy-duty industrial submersible pump (15 kW, 400V) for large-scale dewatering and dirty water drainage. With up to 86.4 m³/hour and 56 meters head, it is built for continuous operation under the harshest conditions in construction, mining, and industry.
The pump casing and motor are made of wear-resistant cast iron, and the open free-flow impeller is made of chrome steel casting. With a double mechanical shaft seal made of silicon carbide (SiC) and built-in thermal motor protection, the 4150 is resistant to abrasive, contaminated water and continuous operation.
Which SPT submersible pump do I need?
Choose based on power, head, and flow rate. The 4150 delivers up to 86.4 m³/hour and 56 meters head. If you need more pressure or flow rate, consider a heavier model from the SPT 215–8220 series. Unsure about the right choice? Ask us for no-obligation advice.
