Jandy FloPro

The FloPro is Jandy's compact, medium-head pump, and the most interesting thing about it is what is missing from the current range.

Jandy prints the discontinued models under "Not DOE Compliant"

The FloPro brochure has two specification tables. The first is headed Residential FloPro Pumps, DOE Compliant and lists three models. The second is headed Residential FloPro Pumps, Not DOE Compliant, and carries this footnote:

Pumps not meeting DOE compliance standards will cease manufacturing on or before July 18, 2021. Specifications are being provided for historical reference.

That second table is the FloPro 1.5, 2.0 and 2.5 and the 1.5 and 2.0 two-speeds. They are not exempt, not commercial and not available. They are printed so an owner can identify a pump already on the pad.

It is worth setting that against the Stealth, Jandy's other single-speed line, which footnotes its own large models as exempt from DOE enforcement and still sells them. Same manufacturer, same regulation, two different outcomes — because the Stealth's big models are commercial machines outside the rule's scope, and the FloPro's were residential pumps inside it.

So the federal rule took the top half of one line and left the other alone. If you are looking at a 2 HP FloPro, you are looking at a pump that stopped being made five years ago.

What is left, and the two-speed is the good one

Three models, and the efficiency ordering is not what the horsepower suggests:

• FHPM.75 — 0.95 THP, WEF 4.1 at 230 V and 4.3 at 115 V, 40.6 lb
• FHPM1.0 — 1.24 THP and WEF 3.5, or 1.14 THP and WEF 3.6, depending on the version (see below), 41.2 lb
• FHPM1.0-2, two speed — 1.14 THP, WEF 5.6, 46.5 lb, 230 V only

The two-speed moves 55 to 60 percent more water per kilowatt-hour than the single-speed of the same nominal size, and it is the model Jandy points at in its own energy copy. On a pump line where the alternative is a fixed 3450 RPM, that is the whole argument, and it costs about six pounds of extra motor.

It is still not a variable-speed pump. The VS FloPro starts at WEF 9.0 and runs down to 600 RPM, which a two-speed cannot approach, and it carries a three-year warranty where every FloPro gets one. But between the two single-speeds and the two-speed, on the same pad, at the same plumbing, the two-speed is the one that pays.

Jandy's own documents disagree about the 1.0 HP, and both are right

Worth flagging because the numbers are not close.

For the same model number, FHPM1.0:

• The brochure and the product page give 1.24 THP, WEF 3.5, and 7.1 / 14.2 amps
• The manual, H0315300 Rev. U, gives 1.14 THP, WEF 3.6, and 5.4–5.2 / 10.3 amps

Carton weight and overall length match across all three, so it is the same pump body.

The Department of Energy's certification database explains it. Jandy has certified two versions under this one model number: FHPM1.0 (v1) at 1.25 total horsepower and WEF 3.5, and FHPM1.0 (v2) at 1.14 and WEF 3.6. The brochure and product page describe the first, with its horsepower given as 1.24 rather than DOE's 1.25, and the manual describes the second. Neither set of figures is a mistake.

The model number alone does not tell you which version is on your pad, so read the amps on the pump's own label. If you are wiring for one you have not seen yet, size the circuit from the higher draw, 7.1 / 14.2 amps. That is the conservative direction anyway.

Medium head, and what that means next to the Stealth

Jandy sells two single-speed lines and the difference is head, not size.

The Stealth is the high-head pump, sold as commercial grade and available up to 5.5 THP. The FloPro is medium head in an ultra compact body, and Jandy's own pitch for it is tight equipment areas.

At the small end they nearly meet. FHPM.75 and the Stealth SHPM.75 are both 0.95 total horsepower, and both draw 4.5–4.4 amps at 230 volts. What differs is the wet end and therefore the shape of the curve: the FloPro moves more water against less resistance, the Stealth pushes harder against more.

That matters for a pool with a long run to a raised spa, an in-floor system or a tall solar array, where head is the constraint. For an ordinary pool with the pad near the water, medium head is the right answer and the compact body is a bonus.

They also share parts. The mechanical seal, R0479400, is the same on both, as are the drain plugs and the motor hardware kit — so a pad running one of each carries fewer spares than the two model ranges suggest.

The base kit is the VS FloPro's

Same system, same four configurations, same part numbers, and Jandy publishes the same table naming which competitor pump each one replaces — Hayward Super Pump and Pentair SuperFlo need no base, Pentair WhisperFlo needs the spacers in the box, and the Sta-Rite Dura-Glas family needs the large base you have to order separately as R0546400.

The VS FloPro page has the full mapping and the suction-height figures rather than repeating them here. The short version for a FloPro buyer is the same: check what you are pulling out before you order, because one of the four options is not in the box.

Two feet, not ten

The specification says certified to 10 feet of self-priming lift. The installation instruction says something more useful.

Jandy recommends installing the pump within 2 feet above water level, and if it has to sit higher than that, fitting a check valve on the suction line to hold water in the plumbing while the pump is off.

Those are different claims and both are true. Ten feet is what the pump can do from a standing start. Two feet is where it will still be priming reliably in five years, when the lid o-ring has aged and the suction side has picked up the small leaks every pool plumbing system picks up. A pump that primes on the bench and struggles on the pad is usually being asked for the first number when it was installed for the second.

The lid, and the one rule about it

The cam-lock lid is meant to come off by hand, with alignment indicators to line it up, because Jandy expects you in the basket regularly — a blocked strainer basket is one of the warranty exclusions.

Hand tighten only. No tool. The manual repeats it in the start-up procedure for both flooded and above-water installations, which is a fair signal about how often the ring gets cracked.

And when the lid is off, clear the debris from the o-ring seat rather than just looking at the o-ring. Jandy's maintenance routine calls for lifting the ring out to do it, and grit on the seat is a more common air leak than a perished ring.
