Professional Wastewater Submersible Pump
The SPT 355 is a powerful three-phase submersible pump (5.5 kW, 400V) for heavy-duty tasks. With up to 70 m³/hour and 32 meters of head, it effortlessly pumps sandy and gravel-laden dirty water in construction pits, industry, and municipal dewatering applications.
The pump housing and motor are made of wear-resistant cast iron, and the open channel 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 355 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 355 delivers up to 70 m³/hour and 32 meters of head. If you need more pressure or flow, consider a heavier model from the SPT 215–8220 series. If you are unsure about the right choice, feel free to ask us for advice.
