Pool Pump Attributes

A pool pump is the circulation heart of a pool, spa, or water feature — a motor-driven centrifugal pump, usually self-priming with an integral hair-and-lint strainer, pulling from skimmer and main drain and pushing through filter, heater, and sanitizer. Buyers are builders, service techs replacing a failed pump the same day, specialty retailers, and commercial aquatic facilities. Nearly every sale is a replacement, decided at the pad by plumbing size, available voltage, and whether the pump will talk to the existing automation.

Horsepower here is not one number: label HP × service factor = total horsepower (THP), so a 1.0 HP full-rated pump and a 1.5 HP up-rated pump can be the same casting. DOE requires THP on the label; supplier feeds still send label HP.

The 2021 DOE dedicated-purpose pool pump rule made WEF and hydraulic horsepower the governing metrics, and California Title 20 gates sale on a MAEDbS listing. Neither field exists in most catalogs. And the number buyers actually need — flow at head, at a given RPM — exists only as a curve inside a PDF.

Core

Every SKU needs these. Without them the record is not a product, it is a row.

Pump Type
enum
Self-priming pool filter pump

DOE regulates each dedicated-purpose pool pump class differently. A booster pump and a filter pump are not substitutes at the pad.

Pool Application
enum
In-ground

Above-ground pumps sit at or below water line and are not self-priming; in-ground pumps prime above it. Wrong choice will not move water.

Total Horsepower (THP)
number · THP
1.65

Label HP x service factor. The only HP figure that compares across brands, and the one DOE requires on the label.

Speed Control
enum
Variable speed

Since July 2021 most replacement filter pumps at or above 0.711 hhp must be variable speed to meet the WEF minimum.

Suction Port Size
number · in
2

Must match existing suction plumbing or the tech is cutting pipe. Often differs from the discharge port on the same pump.

Discharge Port Size
number · in
2.5

IntelliFlo3 ships 2 in suction x 2.5 in discharge. A single 'port size' field cannot describe it.

Voltage
enum · V
115/230 V (dual)

Dual-voltage pumps need a field-set link; 230 V-only pumps cannot run on a 115 V pad without a new circuit.

Phase
enum
Single

Commercial aquatic pads run three-phase. Single-phase pumps are a hard no on those jobs and vice versa.

Full Load Amps
range · A
0.4-10.0 A at 230 V

Sizes the breaker and the whip. VS pumps state a range across the RPM band, not a single figure.

Manufacturer Part Number
identifier
W3SP2603VSP

The only reliable key for cross-reference, warranty claims, and matching a supplier feed to a distributor SKU.

GTIN / UPC
identifier
610377435123

Required by every marketplace and by branch scanning. Absent GTIN blocks the listing outright.

Country of Origin
text
Mexico

Drives duty classification, tariff exposure, and buy-domestic requirements on municipal aquatic bids.

Differentiating

What buyers actually compare on. This is where catalogs win or lose the filter.

Weighted Energy Factor (WEF)
number · gal/Wh
9.3

Gallons moved per watt-hour. The DOE compliance metric and the number utility rebate programs qualify against.

Max Flow Rate
number · GPM
170 GPM at 25 ft TDH

Must not exceed the filter's design flow rate. Overpumping a cartridge or sand filter cracks internals.

Performance Curve (Flow vs. Head by RPM)
text
GPM vs. head (ft) at 1000/1500/2400/3000 RPM

The actual sizing input. A VS pump has one curve per speed, so a single max-flow number tells a builder nothing.

Automation Protocol
enum
RS-485

Decides whether the pump drives from an existing controller or needs a relay and a separate timer.

Compliance & identifiers

Standards, regulatory data, and the identifiers channels reject you for missing.

ENERGY STAR Certified
boolean
Yes

Gates most utility rebates. Certification covers single-phase pumps rated above 0 and below 2.5 hhp.

CEC Title 20 / MAEDbS Listed
boolean
Yes

California bars sale of any dedicated-purpose pool pump not certified into the MAEDbS database.

The fields that aren't in the schema at all

What most pool pumps catalogs are missing.

The table above is the schema most catalogs already have. These are the attributes that usually aren't in it — each one surfaced by a signal from the live market rather than by an audit of what's already there. This is what Anglera's Schema Foundry does on a real catalog, in this category.

Search signal
+ Weighted Energy Factor (WEF)

DOE requires WEF on the pump label and utility rebate programs qualify pumps by it, but distributor filter rails expose HP and speed only. Buyers searching a WEF threshold get zero results.

Pump cannot be matched to a rebate at point of sale. Rebate-driven buyers go to a site that states the number.

Competitor signal
+ Discharge Port Size, separate from suction

Live distributor rails carry one 'Port Size' facet with values like 1.5 in. and 2 in. Real pumps ship 2 in x 2.5 in and 1.5 in x 2 in. One facet cannot represent two ports.

Wrong adapter shipped, pad replumbed on site, or a return. The tech finds out with the old pump already cut out.

Supplier signal
+ Warranty line / channel authorization

Hayward's W3-prefixed SKUs are Open Line, approved for online sale with parts-only coverage. The non-W3 twin is Expert Line, brick-and-mortar, parts and labour. Same pump, no catalog field.

Warranty claim denied at the customer's expense, or a channel authorization breach the distributor did not intend.

Search signal
+ Automation protocol / control compatibility

Buyers ask whether a pump will drive from an existing IntelliCenter or Omni controller. Catalogs list 'variable speed' and stop, with no field for RS-485, relay, or standalone.

RFQ lost to whoever states it. Or an incompatible pump lands on an automated pad and comes straight back.

Supplier signal
+ Performance curve data (GPM vs. head by RPM)

The curve exists as a chart image inside the manufacturer PDF. Nothing in the product record is queryable, so a builder cannot ask which pumps hit 80 GPM at 50 ft of head.

Sizing moves to a phone call or a competitor's calculator. Undersized pumps get returned, oversized ones overrun the filter.

How Schema Foundry finds these

Messy in, governed out.

The same value, spelled every way pool, spa & irrigation suppliers spell it. A filter only works once they agree.

Port Size
2 in.2 in2.0 in.2"2 INCH50 mm
2 in

A live distributor rail lists '2.0 in.' and '2 in.' as two separate facets. One pump sits stranded away from its eleven siblings.

Total Horsepower (THP)
1.5 HP1-1/2 HP1.5 HP up-rated1.0 HP SF 1.651.65 THP1.65 HP
1.65 THP

Label HP is meaningless without service factor. Two pumps both feeding as '1.5 HP' are routinely not the same pump.

Voltage
115/230V115V/230V208-230/460 V208 - 230/460 V110-120/220-240Dual Voltage
115/230 V (dual)

The same live rail carries '208-230/460 V' and '208 - 230/460 V' as two facets. A whitespace difference splits the count.

Speed Control
VariableVSVar. SpeedVSF8-speedTwo Speed
Variable speed

VSF is still variable speed. '8-speed' is a VS pump with eight presets, not a multi-speed pump, and must not collapse to 'Two Speed'.

What buyers ask

Every one of these should be answerable from the attributes above. If it isn't, that's a gap.

  • Will this run off my IntelliCenter, or do I need a relay and a separate timer?
  • Is this the 2 inch or the 1.5 inch pump, and are the unions in the box?
  • My old pump says 1.5 HP. Is a 1.65 THP variable speed a straight swap?
  • What WEF do I need to hit to qualify for the utility rebate?
  • Can I legally sell this pump into California?
  • How many GPM will it do at 50 ft of head at 1800 RPM?
  • Is this the W3 model or the dealer model, and what is the warranty difference?
  • Will this overrun the design flow rate on my existing cartridge filter?

Pool Pumps data, in practice

Why does the same pump appear as 1.0 HP, 1.5 HP, and 1.65 THP?

Because label HP alone does not describe a pool motor. Total horsepower = label HP x service factor. A 1.0 HP motor with a 1.65 service factor and a 1.5 HP motor with a 1.1 service factor are both 1.65 THP, historically sold as 'full-rated' and 'up-rated' versions of the same casting, differing only by the label. The 2021 DOE rule requires THP on the product label precisely to end this, but supplier feeds still ship the old label HP, and both spellings arrive for the same SKU. Govern on THP, keep label HP and service factor as separate stored fields, and let the filter rail expose THP.

Do we need WEF on every pump record?

On every dedicated-purpose pool pump, yes. WEF is the DOE compliance metric, gallons moved per watt-hour, and it determines whether a pump is legal to manufacture, whether it can carry ENERGY STAR, and whether a utility rebate program will pay out on it. It is printed on the label. It is rarely in the catalog. Since most inground pump sales are rebate-influenced, a record without WEF cannot answer the question the buyer is actually asking. Hydraulic horsepower (hhp) belongs alongside it: DOE does not require hhp on the label, but it sets the WEF minimum a pump must meet and drives ENERGY STAR eligibility.

Should suction and discharge port size be one field or two?

Two. A single 'Port Size' facet is the most common structural defect in this category. Pentair's IntelliFlo3 is 2 in suction by 2.5 in discharge. Hayward's Super Pump family ships 2 in ports with adapters down to 1.5 in. A one-field model forces an editor to pick one number and drop the other, and the field tech discovers the omission with the old pump already cut out of the plumbing. Store suction and discharge separately, plus a boolean for whether unions and reducer adapters ship in the box. That last one currently lives in product titles, not in a field.

How should we handle Hayward W3 versus non-W3 SKUs?

As distinct products with a governed channel attribute, not as duplicates to be merged. Hayward's Open Line SKUs carry the W3 prefix, are approved for online and brick-and-mortar sale, and carry parts-only warranty coverage. The Expert Line equivalent is approved for brick-and-mortar sale only and carries parts and labour. The pump is physically the same; the obligation is not. Without a warranty-line field, a merge rule that keys on manufacturer and specs will happily collapse the two, and the first sign of trouble is a denied warranty claim.
