Goulds Water Technology
A Goulds Water Technology jet pump is a centrifugal pump paired with a jet (ejector) assembly that lets a surface-mounted pump draw water up from a well, cistern, lake, or river. The line comes in three forms, split by how far the water sits below the pump: shallow-well pumps with a built-in jet, deep-well pumps that put the jet down in the well, and convertible pumps that do either. Watermain Supply supplies all three — sized, with the correct jet assembly and control valve, to your well. This page covers each type and how to choose.

Every jet pump on this page supplies fresh water to a home, cabin, farm, or light-commercial system. Which of the three you need comes down to a single measurement — the depth from the pump to the water — and, for a convertible, whether you want one pump that can do both.
Within about 25 ft of the pump → shallow well. A shallow-well jet pump keeps the jet assembly built into the pump and runs a single pipe to the source. That 25 ft covers vertical lift plus friction loss in the suction pipe, and the same pump makes an excellent city-water booster or cistern/tank pump.
Deeper than 25 ft → deep well. A deep-well jet pump places the jet assembly down in the well on a two-pipe setup, letting a surface pump reach water far below suction range. Deep-well systems come as twin-pipe (for wells 4 in and larger) or packer (for 2 in and 3 in casings), in vertical and horizontal, single- and multi-stage builds.
Not sure, or want flexibility → convertible. A convertible pump ships ready to run shallow with a bolt-on shallow-well adapter, or deep with a jet assembly placed in the well — one pump that converts between the two.
A jet pump recirculates part of its own output through a nozzle and venturi — the “jet” — to boost the vacuum at the intake. Where that jet sits, and how many pipes run to the well, is the whole difference between shallow and deep.
Deep-well systems need back pressure to work. The jet assembly relies on drive-water pressure, so a deep-well jet pump uses a pressure control valve in the discharge line, set to the depth. The valve, the jet assembly, and the well casing size all have to be matched to the job — which is where sizing matters.
The number that picks the pump is how far the water level sits below the pump. A deep well with water standing 15 ft down is a shallow-well job; the same well drawn down to 70 ft is a deep-well, two-pipe job. Send us the depth to water and the casing size and we size it.
Nominal HP, lift, and depth figures below are approximate and vary by model, jet assembly, and control-valve setting. Watermain Supply provides engineering-led sizing and selection; the jet assembly, control valve, and duty point are confirmed against Goulds published data before you order.
Each type below links to its product page. All run a standard 30–50 psi pressure switch and handle liquid temperatures up to 140 °F.
If the water sits within about 25 ft of the pump, a shallow-well pump handles it on one pipe. Past 25 ft you need a deep-well pump with the jet placed in the well on two pipes. If you want a single pump that can do either now or later, the convertible is the answer — give us the depth to water and casing size and we’ll spec it.
| Type | System | HP | Reach | Reach For It When |
|---|---|---|---|---|
| Shallow Well | 1-pipe, built-in jet | 1/2–1-1/2 | to ~25 ft | Water within 25 ft; cistern, tank, or booster |
| Deep Well | 2-pipe, jet in well (twin-pipe / packer) | 1/2–3 | >25 ft, to ~200 ft* | Wells beyond suction reach |
| Convertible | Shallow (adapter) or deep (jet in well) | 1/2–1-1/2 | to 25 ft, or >25 ft* | Uncertain depth, or wanting flexibility |
A jet pump is more than the pump — on a deep well, the jet assembly and control valve do the real work, and both are sized to your well. Send us these and we return an engineering-led selection.
1. Depth to water. The distance from the pump down to the static water level. Under ~25 ft points to a shallow-well pump; deeper points to a deep-well or convertible with a jet assembly in the well.
2. Well casing size. This decides the deep-well system type — twin-pipe for wells 4 in and larger, packer for 2 in and 3 in casings.
3. Flow you need (GPM) and pressure (PSI). How much water at what pressure, which drives HP and the jet-assembly / control-valve selection.
4. The setup. New well, cistern or tank, city-water booster, or replacing an existing jet pump — tell us which and any model you’re matching.
A pump recommendation with the nominal duty point — and, for a deep well, the correct jet assembly and pressure control valve for your depth and casing — all confirmed against Goulds published data. We don’t commit a final model or duty point until it’s verified for your numbers.
Fresh-water supply and pressure boosting across homes, cabins, farms, and light-commercial systems.
Goulds jet pumps supply homes, cabins, and farms from a private well — shallow or deep — and pressurize water from cisterns and storage tanks, lakes and rivers, and city-water booster systems where incoming pressure is low. Convertible models cover the same work when the water sits deeper, and every setup pairs with a pressure tank and a 30–50 psi switch to deliver steady household pressure.
