Three models cover 1 HP and 1.5 HP outputs in single-speed and 2-speed configurations. All share the same core design: push-button horizontal\/vertical discharge conversion, industrial-size strainer basket, quick-disconnect intake and discharge connections, stainless steel shaft, and an integrated automatic thermal overload protector.\u003c\/p\u003e\n\n  \u003ca class=\"jump-link\" href=\"#powerflo-products\"\u003eSkip to PowerFlo Matrix Pump Products\u003c\/a\u003e\n\n  \u003ch2\u003ePowerFlo Matrix Key Features\u003c\/h2\u003e\n\n  \u003cp\u003eThe push-button discharge orientation is one of the PowerFlo Matrix's most practical features — converting between vertical and horizontal discharge with a single press lets the pump fit a wider range of equipment pad layouts without additional fittings or pipe modifications.

The high-flow Noryl impeller has wide openings to resist clogging from leaves and debris.\u003c\/p\u003e\n\n  \u003ch2\u003eChoosing Between the 1 HP, 1.5 HP, and 1.5 HP 2-Speed Models\u003c\/h2\u003e\n\n  \u003cp\u003eThe 1 HP model suits smaller above-ground pools and filter setups where the pump's output at actual system head stays within the filter's rated flow ceiling. The 1.5 HP single-speed delivers more head and flow for larger pools or longer plumbing runs. The 1.5 HP 2-speed adds a low-speed setting for extended filtration cycles at significantly reduced energy consumption — the low speed runs the pump at roughly one-quarter the electricity of high speed, which can substantially reduce operating costs over a full season when the pool only needs circulation rather than peak filtration output.\u003c\/p\u003e\n\n  \u003cdiv class=\"mc-table-wrapper\"\u003e\n    \u003ctable class=\"mc-table\"\u003e\n      \u003cthead\u003e\n        \u003ctr\u003e\n          \u003cth\u003eProduct\u003c\/th\u003e\n          \u003cth\u003eHP\u003c\/th\u003e\n          \u003cth\u003eSpeeds\u003c\/th\u003e\n          \u003cth\u003eApplication\u003c\/th\u003e\n        \u003c\/tr\u003e\n      \u003c\/thead\u003e\n      \u003ctbody\u003e\n        \u003ctr\u003e\n          \u003ctd\u003e\u003ca href=\"https:\/\/nonstopswim.com\/products\/hayward-powerflo-matrix-1-hp-above-ground-pool-pump\"\u003eHayward PowerFlo Matrix 1 HP Above-Ground Pool Pump\u003c\/a\u003e\u003c\/td\u003e\n          \u003ctd\u003e1 HP\u003c\/td\u003e\n          \u003ctd\u003eSingle\u003c\/td\u003e\n          \u003ctd\u003eAbove-ground\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n          \u003ctd\u003e\u003ca href=\"https:\/\/nonstopswim.com\/products\/hayward-powerflo-matrix-1-5-hp-above-ground-pool-pump\"\u003eHayward PowerFlo Matrix 1.5 HP Above-Ground Pool Pump\u003c\/a\u003e\u003c\/td\u003e\n          \u003ctd\u003e1.5 HP\u003c\/td\u003e\n          \u003ctd\u003eSingle\u003c\/td\u003e\n          \u003ctd\u003eAbove-ground\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n          \u003ctd\u003e\u003ca href=\"https:\/\/nonstopswim.com\/products\/hayward-powerflo-matrix-1-5-hp-2-speed-above-ground-pool-pump\"\u003eHayward PowerFlo Matrix 1.5 HP 2-Speed Above-Ground Pool Pump\u003c\/a\u003e\u003c\/td\u003e\n          \u003ctd\u003e1.5 HP\u003c\/td\u003e\n          \u003ctd\u003e2-Speed\u003c\/td\u003e\n          \u003ctd\u003eAbove-ground\u003c\/td\u003e\n        \u003c\/tr\u003e\n      \u003c\/tbody\u003e\n    \u003c\/table\u003e\n  \u003c\/div\u003e\n\n  \u003cp class=\"compat-note\"\u003eAll PowerFlo Matrix models are designed for above-ground and on-ground pool applications.

It uses the same compact body as the Matrix 1 HP, with a horizontal\/vertical discharge that switches orientation with a button press. Upgrading from 1 HP to 1.5 HP is a direct pump swap with no plumbing changes. The only thing to verify before the swap is the electrical circuit; the 1.5 HP requires a 20-amp circuit versus the 15 amps the 1 HP needs.\u003c\/p\u003e\n\u003ch2\u003eHayward PowerFlo Matrix 1.5 HP vs. 1 HP: Which Do You Need?\u003c\/h2\u003e\n\u003cp\u003eThe 1 HP handles pools up to roughly 18,000 gallons on a standard 8 to 10 hour daily run. Once pool volume approaches 20,000 gallons, or the plumbing adds friction through longer hose runs or multiple fittings, the 1 HP starts running near its ceiling, which increases thermal overload events on hot days and slows recovery after heavy bather use. The 1.5 HP provides headroom that keeps the motor comfortable even on a large pool with a suction-side cleaner running simultaneously. The 1.5 HP also draws 14.2A vs. 10.8A for the 1 HP, so confirm your outdoor circuit is 20 amps before ordering.\u003c\/p\u003e\n\u003ch2\u003eHayward PowerFlo Matrix 1.5 HP W3SP1593 - Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ccaption\u003eHayward PowerFlo Matrix 1.5 HP Above Ground Pool Pump W3SP1593 - Full Specifications\u003c\/caption\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\"\u003eSpecification\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU \/ Model\u003c\/td\u003e\n\u003ctd\u003eW3SP1593\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor Horsepower\u003c\/td\u003e\n\u003ctd\u003e1.5 HP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpeed Type\u003c\/td\u003e\n\u003ctd\u003eSingle speed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor RPM\u003c\/td\u003e\n\u003ctd\u003e3450 RPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage\u003c\/td\u003e\n\u003ctd\u003e115V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAmperage\u003c\/td\u003e\n\u003ctd\u003e14.2A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCircuit Required\u003c\/td\u003e\n\u003ctd\u003eDedicated 20-amp GFCI-protected outdoor circuit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDischarge Orientation\u003c\/td\u003e\n\u003ctd\u003eHorizontal\/vertical (switchable with button press)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePort Size\u003c\/td\u003e\n\u003ctd\u003e1.5\" and 2\" connections\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Flow Rate\u003c\/td\u003e\n\u003ctd\u003eApprox. 53 GPM at low head\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBasket Access\u003c\/td\u003e\n\u003ctd\u003eFront-access strainer basket\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePool Application\u003c\/td\u003e\n\u003ctd\u003eAbove ground pools above ground pools\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Material\u003c\/td\u003e\n\u003ctd\u003eCorrosion-resistant polymer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eUL Listed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e1 year\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cdiv class=\"note\"\u003eSpecifications are subject to manufacturer revision.

The W3SP1593 uses the same body dimensions, port positions, and connection sizes as the Matrix 1 HP. An existing 1 HP Matrix installation can be upgraded to the 1.5 HP by swapping the pump body and connecting to the same hose fittings already in place. Verify the electrical circuit is rated for 20 amps before making the swap; the 1.5 HP requires 20 amps versus the 15 amps adequate for the 1 HP.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat circuit do I need for the PowerFlo Matrix 1.5 HP?\u003c\/summary\u003e\n\u003cp\u003eA dedicated 20-amp GFCI-protected outdoor circuit. The pump draws 14.2A at full load; running it on a 15-amp circuit will cause the breaker to trip under sustained load. If your pool area currently has only a 15-amp outlet, upgrading the circuit breaker and outlet to 20 amps is required before installing this pump.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWill my existing filter handle the 1.5 HP's flow rate?\u003c\/summary\u003e\n\u003cp\u003eCheck it. A filter sized for a 1 HP pump will run at elevated pressure under the 1.5 HP's higher flow rate, which restricts filtration and shortens filter media life. For a 20,000-gallon pool, an above ground sand filter with a 19 to 22 inch tank diameter rated for 45 to 55 GPM is appropriate for the Matrix 1.5 HP's output.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat timer works with this pump?\u003c\/summary\u003e\n\u003cp\u003eA standard plug-in outdoor pool timer rated for 20 amps at 115V. Confirm the timer's amperage rating before connecting; a 15-amp timer is undersized for the 1.5 HP's 14.2A draw and can overheat under sustained load.

The difference is physical layout. The Matrix has a side-discharge port and front-access basket in a compact low-profile body, which suits tight installations and horizontal filter connections. The PowerFlo LX has a larger footprint, top-load basket, and top or angled discharge, which suits open installations where basket capacity and easier access are priorities.

It has two fixed operating speeds: 3450 RPM (high) for vacuuming, running a suction-side cleaner, and recovering water quality, and 1725 RPM (low) for overnight filtration where you want lower energy draw and less noise. Because power scales with the cube of motor speed, dropping to half the RPM uses roughly one-eighth the electricity. Running low speed for 8 to 10 hours overnight rather than high speed for a shorter window is where most of the savings come from.\u003c\/p\u003e\n\u003cp\u003eThe pump body is physically identical to the single speed Matrix models, so it drops into an existing Matrix installation without any plumbing changes. The only difference is the electrical wiring, which needs a two-circuit timer or switch to control both speed leads.\u003c\/p\u003e\n\u003ch2\u003eHow 2-Speed Control Works on the W3SP1520\u003c\/h2\u003e\n\u003cp\u003eTwo-speed motors have two independent winding sets inside the motor housing, each with its own wire lead. Speed selection is a wiring decision, not a setting on the pump. In practice this means you need either a two-speed timer (which switches between the high and low speed leads on a daily schedule) or a two-position switch for manual selection at the equipment pad. A standard single-circuit pool timer can only control one speed; it cannot switch between both leads automatically.\u003c\/p\u003e\n\u003cdiv class=\"note\"\u003eTwo-speed pump wiring connects multiple motor leads to a timer or switching circuit. If you are not experienced with pool equipment wiring, a licensed electrician should handle this. An incorrect connection between the high and low speed leads can damage the motor.

Variable speed pumps have a continuous range of speeds and programmable schedules; this pump switches between two fixed settings using external wiring. It costs less than a variable speed model and is simpler to control, but does not offer the fine-tuned energy optimization of a full variable speed system.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan it replace a single speed Matrix 1.5 HP without replumbing?\u003c\/summary\u003e\n\u003cp\u003eYes. The W3SP1520 uses the same body dimensions, port positions, and plumbing connections as the PowerFlo Matrix 1.5 HP single speed. No plumbing modification is required. Only the electrical wiring changes to accommodate the second motor lead for low-speed operation.

You need either a two-speed mechanical timer (which manages both leads on a daily schedule) or a two-position switch wired to both leads for manual speed selection at the equipment pad. The installation guide documents the wiring configuration for both options.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eShould I start the pump on high or low speed?\u003c\/summary\u003e\n\u003cp\u003eAlways start on high speed for initial priming. High speed produces the suction needed to draw water through the system and clear air from the plumbing. Once the pump is primed and water is circulating, the timer or switch can transition to low speed for the filtration cycle. Starting directly on low speed when the system is not already primed can stress the shaft seal and may not establish full prime before thermal protection activates.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow much does the low-speed setting actually save on electricity?\u003c\/summary\u003e\n\u003cp\u003eBecause power scales with the cube of motor speed, dropping from 3450 RPM to 1725 RPM (half the speed) cuts power draw to roughly one-eighth of high speed. The low-speed setting draws approximately 3 to 4 amps at 115V versus 14.2 amps at high speed. Running low speed for 8 hours overnight instead of high speed for the same period reduces that portion of electricity consumption by roughly 75%.
