Jandy Stealth

The Stealth is Jandy's high-head single-speed pump — the other one being the FloPro, which is medium head in a more compact body — and the most useful thing on its spec sheet is not a performance number. It is the evidence that two pumps you would compare against each other are the same pump.

SHPF and SHPM are the same machine, twice

Jandy sells the Stealth under two prefixes. SHPF is full rated. SHPM is max rated. Set the two tables side by side and the pattern is exact:

• SHPF.50 and SHPM.75 — both 0.95 total horsepower
• SHPF1.0 and SHPM1.5 — both 1.65 THP
• SHPF1.5 and SHPM2.0 — both 2.21 THP
• SHPF2.0 and SHPM2.5 — both 2.60 THP

A pump badged 1.5 horsepower and a pump badged 1.0 horsepower, from the same manufacturer, in the same range, with identical total horsepower. The difference is which number the label reports: the nameplate, or the nameplate with the service factor already folded in.

And Jandy's parts list settles any doubt. SHPF1.0 and SHPM1.5 take the same impeller kit, R0807202. Every pair above shares one impeller number. They are not similar pumps. They are the same wet end with a differently labeled motor.

The pump sizing guide explains why horsepower on a box is not a comparable number. This is that argument as a product line. The practical version: compare total horsepower, and if you are buying parts, order by the prefix rather than the number.

One residential model, and everything above it is commercial

Look at the manual and the Stealth appears to span 0.95 to 5.75 THP. Look at what Jandy currently sells and it does not.

The residential Stealth is a single pump — 0.95 THP, WEF 3.6, sold as SHPF.50 or SHPM.75. That is the whole residential range.

Everything larger sits in two tables the brochure labels Commercial 1-Phase and Commercial 3-Phase, and both carry the same footnote in Jandy's own words: exempt from DOE DPPP enforcement.

That footnote is the honest explanation for how a 5.5 horsepower single-speed pump is still on sale in 2026. Since 2021 the Department of Energy has effectively required variable speed on dedicated-purpose pool pumps above 0.711 hydraulic horsepower, which is the water work in its test rather than the horsepower on the label. These are not compliant with that rule. They are outside it.

So the practical reading of the range:

• Buying a residential filtration pump? There is exactly one Stealth for you, at 0.95 THP.
• Seeing a 2 HP or 3 HP Stealth listed? Every current one is three phase, which a house does not have.
• The only single-phase pump above 0.95 THP is the SHPF5.0TEFC at 5.5 THP, drawing 24.7 amps and asking for 4-inch pipe. That is a commercial machine.

Everything between those two — the SHPF1.0 through SHPF3.0 single-phase models, the whole SHPM ladder above .75, the two-speed versions — is legacy. They appear in the manual and the parts list because Jandy still supports them, and they have no WEF listed because they are no longer certified for sale. If you own one, parts are available. If you are shopping, it is not on the menu.

The efficiency ladder, and what it costs

WEF is the Department of Energy's measure, in thousands of gallons per kilowatt-hour. Higher is better, and on the Stealth it falls steadily with size:

• 0.95 THP — WEF 3.6
• 1.65 THP, three phase — 2.7
• 2.60 THP, three phase — 2.5
• 3.45 THP, three phase — 2.1
• 5.5 to 5.75 THP — 1.8

The residential pump moves twice as much water per kilowatt-hour as the biggest commercial one. That is the whole argument of the DOE rule in a single manufacturer's own table, and it is why the exemption exists for commercial duty rather than for backyards.

Against the VS FloPro the comparison is less kind still — 9.0 to 11.0 against 3.6 — because a variable-speed pump spends most of its life at a fraction of these speeds. What that difference costs over a season is usually the deciding number.

Single speed also costs you two years of warranty

Easy to miss, and it is in Jandy's warranty rather than the pump's manual.

Jandy warrants variable-speed pumps for three years. Everything else gets one. So choosing a Stealth over a VS FloPro is not only a running-cost decision — it is a two-year difference in coverage on the same pad, from the same manufacturer.

Two more terms that matter here. Commercial applications get one year regardless, which applies to most of this range by definition. And purchased replacement parts carry ninety days.

Then the exclusions that bite on a pump specifically:

• Running it at flow rates below the minimum or above the maximum in the specifications
• A dirty, clogged or blocked strainer basket or impeller — which makes basket cleaning a warranty condition, not housekeeping
• Collateral damage caused by a failed o-ring or basket, so the cheap part failing does not cover the expensive consequence

And the rule that covers everything Jandy sells: no warranty at all on products bought through the Internet or an e-commerce platform. The Jandy brand page has the full policy.

The blue o-ring you are supposed to throw away

This one catches people, and it is unusual enough to be worth its own section.

Every Stealth ships with a blue pressure test o-ring already fitted inside the lid. It is not a spare. It is a disposable part that exists so the plumbing can be pressure tested at commissioning, and Jandy's instruction after a successful test is to discard it.

Three details that go with it:

• Do not open the lid before the pressure test. Jandy's caution is explicit — the blue o-ring can fall out, and it is easy to damage putting it back.
• It seats on its own step, about a quarter inch from the lid seal, and Jandy says to place it there rather than roll it on, so it does not roll off during assembly.
• If you lose or tear it, the replacement is R0479000.

The test itself has hard limits. Never above 35 psi, water only, and never compressed air — trapped air in a pressurized system turns a failure into shrapnel. Jandy says the test is a job for a trained pool professional, and on that point it is right.

Jandy's own pipe sizing

Worth recording because manufacturers rarely publish this and because Jandy's suction figure is more conservative than the code ceiling.

Six feet per second on suction, eight on discharge:

• 1½ in. — 37 GPM suction, 50 GPM discharge
• 2 in. — 62 GPM, 85 GPM
• 2½ in. — 88 GPM, 120 GPM
• 3 in. — 136 GPM, 184 GPM
• 4 in. — 234 GPM, 313 GPM

Two notes from the same page. Equipment more than 100 feet from the water goes up a pipe size. And the pump ships with unions on both ports, which Jandy points out removes the threaded adapters that leak.

The lid rule

Small, specific, and it explains a lot of cracked locking rings.

A tool is allowed to help open the lid. Never use one to tighten it. Hand tight, following the START and LOCKED markings on the ring, and not past LOCKED.

The clear lid is there so you can look at the basket without opening the pump, which is what Jandy asks you to do as routine maintenance. Given that a blocked basket is a warranty exclusion, that glance is worth building into the weekly check of the pad.
