Submersible water pump pressure
Those pumps are rated in feet or meters of head pressure. Most submersible pumps similar to what you show are only rated to 15-20’ of head this is the equivalent of 7-10 psi or the maximum pressure it can develop. For that amountc of power it draws it probably has a fair volume.
To get more pressure you usually have to sacrifice volume or add horse power.
You may not need the gallons per minute and reducing this for a pump that could pump 60 feet of head pressure or more will provide the spray you are after. A pump that can only pump 10 gallons per minute at 60’ of head pressure may be similar in power as your existing pump but spray closer to what you are used to.
