Madimack Pool Pumps

Upgrade your pool circulation with Madimack InverFLOW variable speed pool pumps — DC brushless motor technology with InverMAC speed control for maximum energy efficiency. PST Pool Supplies stocks the InverFLOW Eco series from $950.00.

Madimack's InverFLOW Eco line applies variable speed technology to inground pool circulation, offering three horsepower configurations for different pool sizes: the F300iNA (1.0hp, 230v, $950.00) for smaller inground pools, the F400iNA (1.35hp, 230v, $1,200.00) for mid-size installations, and the F500iNA (1.8hp, 230v, $1,325.00) for larger pools with higher flow demands. All three operate on 230v single-phase power and share the same InverMAC technology platform — optimized motor speed control that adjusts RPM dynamically across a 30–100% operating range to match actual circulation demand rather than running at fixed full speed.

The DC brushless motor design delivers two key advantages over traditional single-speed pool pumps: dramatically reduced energy consumption at lower speeds and significantly quieter operation. At low-speed filtration settings, a variable speed pump consumes a fraction of the electricity of a single-speed equivalent — the energy savings can offset the higher initial pump cost within the first two to three seasons. Four integrated daily operation timers allow the pump schedule to be programmed for different speeds at different times of day — low speed for overnight filtration, high speed for peak circulation during swim hours. Built-in energy monitoring tracks actual power consumption. Corrosion-resistant hardware construction is designed for long-term exposure to pool water chemistry.

Frequently Asked Questions

How much energy does a Madimack InverFLOW variable speed pump save versus a single-speed pump?
The energy savings from variable speed pumps like the Madimack InverFLOW are substantial and well-documented: The physics: pump energy consumption follows the affinity laws — power consumption decreases by the cube of the speed reduction. Cutting motor speed in half (50%) reduces power consumption to 12.5% of full-speed draw. This is why variable speed pumps achieve dramatic savings even at modest speed reductions. Example calculation: a traditional single-speed 1.5hp pump running 8 hours/day at full speed consumes approximately 9 kWh/day. At $0.15/kWh = $1.35/day, or ~$493/year. A variable speed pump running the same 8 hours — but at 50% speed for 6 hours and 75% speed for 2 hours — consumes approximately 2–3 kWh/day. At $0.15/kWh = $0.30–$0.45/day, or ~$110–$165/year. Annual savings: $330–$380 per pump. The InverFLOW's 30–100% operating range and four programmable daily timers allow the speed schedule to be optimized for actual pool circulation requirements — low speed overnight, higher speed during filtration-intensive periods. Most pool owners recover the variable speed pump's additional cost over a single-speed unit within 2–3 seasons in energy savings alone. Many utilities also offer rebates for variable speed pump installation — check local utility programs before purchasing.
What is InverMAC technology and how does it differ from standard variable speed pump motors?
InverMAC is Madimack's proprietary motor control platform applied to the InverFLOW pump series: Standard VS pump motors: most variable speed pool pumps use permanent magnet motors with inverter-driven speed control — the inverter adjusts the frequency of power supplied to the motor to change RPM. This is effective but the inverter's efficiency varies across the speed range, with some inefficiency at very low speeds. InverMAC technology: Madimack's approach uses optimized motor speed control algorithms that adjust not just frequency but the full power delivery profile to the DC brushless motor. Key advantages: (1) Efficient operation at low speeds — the control algorithm maintains motor efficiency even at the lower end of the 30–100% operating range, where some conventional VS pumps lose efficiency. (2) Precise speed selection — the active panel allows specific speed settings rather than just preset low/medium/high options, enabling fine-tuning to exactly the flow rate the pool system requires. (3) Energy monitoring integration — InverMAC tracks actual power draw and reports consumption, allowing the operator to verify savings and identify if the pump is working harder than expected (which can indicate a flow restriction or filter maintenance need). (4) DC brushless motor compatibility — InverMAC is designed specifically for DC brushless motors, which have inherently lower friction and longer bearing life than brushed motors, contributing to the pump's long-term reliability and efficiency retention over years of operation.
How do I select the right InverFLOW model (F300iNA, F400iNA, or F500iNA) for my pool?
Pump sizing for inground pools depends on two key factors: required flow rate and total dynamic head (resistance) in the plumbing system. General sizing guidance: (1) F300iNA (1.0hp, $950.00): appropriate for smaller inground pools up to approximately 20,000 gallons with standard plumbing (2" main drain and return lines, moderate filter and heater resistance). Also suitable for larger pools where the existing plumbing has been sized for lower flow rates. (2) F400iNA (1.35hp, $1,200.00): mid-range option for pools in the 20,000–35,000 gallon range, or smaller pools with higher resistance plumbing — long pipe runs, 1.5" plumbing, multiple features (spa, water features, cleaners) adding to system resistance. (3) F500iNA (1.8hp, $1,325.00): appropriate for larger pools (35,000+ gallons), pools with extensive features (attached spa, multiple water features, in-floor cleaning system), or installations with high total dynamic head from long pipe runs or undersized plumbing. Important sizing note: all three models run on 230v single-phase power — verify your electrical service before ordering. Variable speed pumps should be sized to run efficiently in the 50–75% speed range during normal filtration — if the pump requires 90%+ speed to meet flow requirements, a larger model is appropriate. If in doubt, sizing up by one tier is preferable to undersizing, as the variable speed control allows a larger pump to run at reduced speed efficiently.
How do I program the InverFLOW's daily operation timers?
The Madimack InverFLOW includes four integrated daily operation timers accessible through the active panel control — here is the general programming approach: Timer setup: (1) Access the timer programming mode through the control panel — the panel typically uses a combination of the speed/mode buttons to enter programming; refer to the InverFLOW manual for the exact button sequence for your model. (2) Each of the four timers allows you to set: a start time, a stop time, and a speed percentage (within the 30–100% range). (3) Timers can overlap — the pump applies the highest-priority timer's settings when multiple timers are active simultaneously. Recommended timer schedule example for a typical residential pool: Timer 1 — overnight filtration: 11pm–7am at 40% speed (low flow, low noise, low cost). Timer 2 — morning filtration: 7am–10am at 60% speed (moderate flow as pool use begins). Timer 3 — peak hours: 10am–6pm at 75% speed (higher flow during swim hours and peak solar heating). Timer 4 — chemical circulation: 6pm–11pm at 50% speed (adequate circulation for evening chemical dosing). Energy monitoring use: after programming, use the InverMAC energy monitoring to verify actual power consumption across the schedule. If the pump is consuming more than expected at a given speed setting, inspect the filter for restriction — a dirty filter increases system resistance and forces the pump to work harder to maintain flow.
