Supplier item number: SPT 322
Pros and cons:
+ Powerful 2.2 kW three-phase pump (400V) for sand and dirty water
+ Open vortex 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 construction & dirty water submersible pump
The SPT 322 is a professional construction and dirty water submersible pump (2.2 kW, 400V) for sandy and gravelly water. Exactly the pump for situations where a regular garden pump fails due to dirt: on construction sites, for dewatering, and in utilities.
Pump housing and motor are made of wear-resistant cast iron, the open vortex impeller of chrome cast steel. With a double mechanical shaft seal made of silicon carbide (SiC) and built-in thermal motor protection, the 322 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 322 delivers up to 50 m³/hour and 21 meters of 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 advice without obligation.
Scope of delivery
