1/2 HP increase yield more volume?

My first thought is the Grundfos (Grundfos 10SQ05-160-115V).

I've read bad things about their 120V motors.

That might have been for their 4 inch pumps?

Further to LLigetfa's comment, the jet will be located within the ejector assembly within the deep well setup shown below in a 4" casing.

Put the injector down the hole and its called a deep well configuration. If the injector is on the pump its a shallow well. This is making sense now. I don't see the injector part on my pump must be an internal piece. Thanks.

If your pump is not equipped with a removable ejector to allow it to be converted to deep well operation, then your pump will be capable for use for only shallow well applications.

Looks like I should be able to see the nozzle portion of the jet assembly inside the pump. I don't see anything in my pumps just the metal case of the pump.

OK just to confirm the terminology here. A deep well jet pump is a pump that is converted from a shallow to a deep well by relocating the injector from the pump to the well. Question: Can a shallow well pump have or benefit from an injector mounted on the pump?

A shallow well jet pump will already have the jet assembly inside the pump housing. A convertible jet pump will have the ejector able to bolt directly the the pump to make is a shallow well pump, or it can be installed down the well to make it a deep well jet.

The operative word is "jet" pump. There are shallow well pumps that don't have a "jet", only impellers.

Picture of the pump or better yet, a model number?

OK that's an important distinction. All my pumps only have impellers. Do they make pumps with an injector mounted on the pump?

There are multi-stage centrifugal suction (shallow) well pumps that have no injector anywhere. They look to me as if they cost more. I don't know if there is another reason that they might be less popular for home wells.
The common jet pump has a built in injector/jet.
The convertible jet pump lets you remove that injector/jet, and thereby convert to a deep well jet pump.
A deep well jet pump expects to be used with an injector/jet down the well.
