Professional heavy-duty dirty water submersible pump
The SPT 8220 is the heaviest submersible pump in the SPT series (22 kW, 400V), built for large-scale dewatering and dirty water drainage in construction, mining, and industry. You can choose from two versions: the 8220N for maximum flow (up to 390 m³/hour) and the 8220H for a higher head (up to 35 meters).
The pump housing and motor are made of wear-resistant cast iron, and the open channel impeller is made of chrome cast steel. With a double mechanical shaft seal made of silicon carbide (SiC) and built-in thermal motor protection, the 8220 is resistant to abrasive, contaminated water and continuous operation.
Which version do I need?
Do you mainly need to pump a lot of water quickly at a limited height? Choose the 8220N (390 m³/hour, 25 m). Does the water need to be pumped higher or over a greater distance? Choose the 8220H (330 m³/hour, 35 m). Unsure? Feel free to ask us for advice.
Scope of delivery
SPT 8220 submersible pump with R 8" discharge connection, in the selected version (N or H). 400V three-phase current; level control is via an external controller (no built-in float).
