RSX(M)2 2-Stage Multistage Pump | Pressure Boosting
Built for the job
Compact stainless steel multistage pump for smaller sprinkler systems and light potable boosting.
The RSX2 and RSXM2 are the smallest stainless steel multistage pump in the RSX range, manufactured by Speroni Pumps. They are built for light potable boosting applications where flow requirements are modest but pressure needs can be significant.
Multistage pumps stack multiple impellers in series: each one adds pressure without adding flow, which is how small motors produce high head.
Three stage-count options let you pick the exact head you need: 4, 5, or 6 stages. All three use the same modest motor platform, so running cost and installation footprint are consistent across the range.
Full stainless steel 304 construction makes this pump suitable for clean potable applications.
Where the Speroni RSX2 and RSXM2 are Used
Small sprinkler systems. Rainwater harvesting pressurisation. Clean water washing systems. Cooling loops on small processing lines. Stored water booster (downstream of air gap). Light commercial potable pressurisation.
Suitable for potable water from a tank or private supply (not for direct mains, not WRAS approved).
Application: Pressurisation units | Sprinklers | Washing | Irrigation | Water supply | Cooling
The Difference between the RSX2 and RSXM2
- An M at the end of the model name means 230V single-phase (RSXM)
- No M means 400V three-phase (RSX).
Choosing Between the Stage Counts
More stages means more pressure. Flow rate is consistent across the three options. Pick based on the head you need.
The number at the end of the product code (−4, −5, −6) is the number of impellers in the pump. More impellers means more stages, and more stages means more pressure.
Important: WRAS Approval
This pump is not WRAS approved and is not for drinking water supply. It is suitable for irrigation, sprinklers, fire systems, rainwater harvesting, cooling loops, and industrial or agricultural water.
