on the back of the jet pump
All shallow well jet pumps use an ejector (or jet), which consists of a nozzle and venturi tube. Centrifugal pumps on the other hand are also shallow well pumps without a jet.
when a water comes out from nozzle and moves straight forward are called jet of water.

The exhaust nozzle on a jet engine that expande and retract depending on thrust
The steering nozzle on a personal watercraft (PWC) is typically located at the rear of the watercraft, directly behind the jet pump. It directs the water flow expelled by the jet pump, allowing the operator to steer the PWC. The nozzle is connected to the steering system, which is controlled by handlebars, enabling maneuverability on the water.
There are different kinds of jet pumps but some of the main components are motor, discharge, jet assembly, lift, suction, nozzle, control value, impeller, and venturi.
Stream of water from jet nozzle
Try unthreading the nozzle and use a PVC cap fitting that fits the thread pattern and screw the cap in place of the jet nozzle. Your Home Depot or Lowes plumbing department should be able to help.
a. A high-velocity fluid stream forced under pressure out of a small-diameter opening or nozzle. b. An outlet, such as a nozzle, used for emitting such a stream. c. Something emitted in or as if in a high-velocity fluid stream: "such myriad and such vivid jets of images" Henry Roth. d. A jet-propelled vehicle, especially a jet-propelled aircraft. e.
