  Convertible Jet Pumps are Well Pumps that can be configured to move water in either Shallow Well or Deep Well Systems. These pumps operate through suction power, in which a pressure differential moves the water in an upward motion.

Most people commonly rely on either shallow well jet pumps, which can draw from water tables up to 25 ft. underground or deep well jet pumps which can draw water from water tables up to 90 ft. underground (depending on the model). Water table levels can sometimes fluctuate, however, whether due to climate, elevation or other factors.

Thus the advantage of the Convertible Jet Pump is that it can help the user adapt to a potentially fluctuating water table. If you want the confidence of knowing that you will be able to get well water no matter the changes, a convertible jet pump may be for you. The pumps sit above ground but can be equipped with a submersible jet ejector assembly to increase operating depth. Keep in mind that the appropriate fittings are are necessary to convert the pump from one application to another.

PumpProducts.com is a proud Goulds Pump distributor and we carry three series of Goulds Convertible Jet Pumps: the J + series, the JRD series and the HSJ series.

In turn, each pump in these three series can be configured in a standard Shallow Well System or in one of two horizontal deep well systems, twin pipe and Packer. The Packer system requires a Packer Adapter inside the well head. The following graphic gives a picture of how each system looks and the fittings required:

The J+ series Convertible Jet Pumps are specifically designed for homes, farms, cottages and booster service. PumpProducts.com carries the J5, J7, J10 and J15 models. Each model in the J+ series is designed with a back pullout design that allows for easy service and maintenance without disturbing the piping. Note that the tubing comes connected for shallow well use; a deep well configuration requires a JDW fittings package or an AV22 kit to make the pressure switch connection.

Unlike with most other types of pumps, the relevant performance statistics of convertible jet pumps will vary greatly depending on the application configuration and fittings used. The charts below show the performance for each model in the J+ Series for a shallow well package and two deep well packages (twin pipe and Packer). Within each chart the flow rate differential depending on the adapter, nozzle and venturi used is also shown.

The JRD Series Jet Pump are specifically designed for use in homes, farms, cottages and for booster service. The primary difference between the J+ series and the JRD series is in construction. J+ pumps contain a motor adapter in the casing while in JRD pumps the front housing connects directly to a plate. J+ models are a little pricier so if you’re looking for a cheaper alternative for the same applications, consider the JRD series.

PumpProducts.com currently carries the JRD5, the JRD5LT, the JRD7 and the JRD10. The following charts give an overview of the relevant performance statistics for the JRD series pumps in shallow well, deep well twin pipe and deep well Packer configurations. Note that the tubing comes connected for shallow well use; a deep well configuration requires a JDW fittings package or an AV22 kit to make the pressure switch connection.

The Goulds HSJ Series Convertible Jet Pumps are multi-stage pumps operating at 60 Hz. These pumps are specifically designed to deliver high capacity flow at greater pressures than the J+ or JRD series. The hex design provides positive drive for the impellers and eliminates any clearance adjustments.

Like its cousins, the HSJ series is also designed for homes, farms, cottages and booster service. We carry the HSJ07N, HSJ10N, the HSJ15N and the HSJ20N. The following charts give an overview of the relevant performance statistics for the HSJ series pumps in shallow well, deep well twin pipe and deep well Packer configurations.
