+ Double mechanical shaft seal (SiC) and thermal protection
- Only as 400V three-phase — no 230V version
Professional Dirty Water Submersible Pump
The SPT 455 is a powerful three-phase submersible pump (5.5 kW, 400V) for tougher jobs. With up to 105 m³/hour and a head of 23 meters, it effortlessly pumps sandy and gravelly dirty water from construction pits, in industry, and for municipal dewatering.
The pump housing and motor are made of wear-resistant cast iron, and the open vortex 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 455 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 455 delivers up to 105 m³/hour and a head of 23 meters. If you need more pressure or flow rate, consider a heavier model from the SPT 215–8220 series. Unsure about the right choice? Feel free to ask us for advice.
