Quick Product Summary
The Madimack InverFLOW Plus 2 HP pool pump, SKU 21103, provides adjustable circulation with an inverter motor, Wi-Fi control and daily scheduling. It is the 2 HP option in the InverFLOW Plus range. Before choosing it as a replacement, match its performance curve to your pool’s flow requirements and confirm the electrical supply and plumbing connections.
Best For
Pool systems whose required flow and resistance call for the 2 HP performance curve. Confirm that the filter, plumbing and other equipment can accept the selected operating flow.
Why This Matters
- Choose circulation settings around filtration and equipment needs instead of treating every task as a full-speed job.
- Compare the pump curve at your system’s operating head to reduce the risk of choosing by horsepower alone.
- Plan the electrical, plumbing and control connections before replacing your current pump.
Common Signs You Need This / Use This When
- Your current circulation pump needs replacement and its model alone does not establish the right replacement size.
- You want to schedule different operating periods for your pool.
- You are comparing inverter pumps and want model-specific performance information before discussing installation.

Compatibility / Fitment Notes
Confirm the exact SKU 21103 when comparing quotes or ordering. A 2 HP label does not establish a direct replacement for every pump with the same advertised horsepower. Your installer should compare the pump curve with the pool’s required flow and total dynamic head, and check the flow limits of the filter, heater and any other connected equipment.
Madimack identifies the inlet and outlet as 2-inch BSP connections. That description is not a promise that the pump will screw directly into your current unions or match the spacing of an existing pump. Verify the union connections, any required adapters and the available space at the equipment pad before purchase.
This is a dual-voltage model, but available output depends on the electrical supply. The published flow figures shown here reference 230 V; do not assume identical performance on a different supply. Have the installer check the unit’s nameplate, current manual and any external control requirements for the planned installation.
Installation / Use Notes
Have a qualified pool-equipment professional install and commission the pump using the current Madimack instructions. Before installation, verify the electrical supply, plumbing connections, equipment-pad clearance and required operating flow. Set the daily schedule and pump output to meet the connected equipment’s requirements. Review operation after setup and follow Madimack’s maintenance guidance.
Review the Madimack InverFLOW Plus installation manual and U.S. product brochure and pump curves with your installer before purchase.

Frequently Asked Questions
Can the Madimack 21103 replace my current 2 HP pool pump?
It may be a suitable replacement if its performance curve, electrical requirements and plumbing connections match your system. Match the required flow at your system’s operating head; horsepower alone does not confirm compatibility.
What voltage does the InverFLOW Plus 2 HP use?
Madimack lists this dual-voltage series with a 90–250 V, 50/60 Hz operating range. Have your installer confirm the unit’s nameplate and supply requirements. Published flow figures reference 230 V, and performance can differ at other supply voltages.
How much water can the 21103 pump move?
Madimack publishes a maximum of 136 GPM and 123 GPM at 33 ft of head for this model, referenced to a 230 V supply. Actual flow depends on plumbing resistance, the operating setting and supply voltage; maximum flow is not guaranteed in an installed pool.
Does this pump have Wi-Fi and scheduling?
Yes. InverFLOW Plus includes Wi-Fi control and four daily timers. Configure the operating schedule and speed settings around your pool’s filtration and connected-equipment requirements.
Will the pump connect to my existing 2-inch plumbing?
The manufacturer lists 2-inch BSP pump connections. Verify the actual union and adapter requirements with your installer; that thread specification does not establish a direct fit to every existing 2-inch plumbing connection.
Compare other pool pumps, explore Madimack pool equipment, or review pool filters when planning a compatible equipment setup.
