Supplier Part Number: SPT 150R
Pros and Cons:
+ Built-in agitator: pumps sludge, silt, drilling mud, and bentonite
+ Large free passage of 30 mm
+ Robust cast iron with chrome steel impeller — wear-resistant
+ Double mechanical shaft seal (SiC) and thermal protection
- Only available as 400V three-phase power — no 230V version
Professional submersible pump with agitator
The SPT 150R is a three-phase submersible pump (9 kW, 400V) with an agitator. The agitator stirs up settled sand and sludge, allowing the pump to reliably pump difficult mixtures such as sludge, silt, drilling mud, and bentonite — up to 171 m³/hour. Designed for construction, mining, and industry.
The pump housing and motor are made of wear-resistant cast iron, the impeller of chrome steel cast, and the agitator is directly on the shaft. A double mechanical shaft seal made of silicon carbide (SiC) and built-in thermal motor protection ensure a long service life under heavy conditions.
Which SPT submersible pump do I need?
Choose based on power, head, and flow rate. The 150R delivers up to 171 m³/hour and 21.5 meters of head. If you need more pressure or flow, consider a heavier model from the SPT 215–8220 series. Unsure about the right choice? Ask us for non-binding advice.
Scope of delivery
SPT 150R submersible pump with agitator and discharge connection R 6". 400V three-phase power; level switching is via an external control (no built-in float).
