This article compares the pumping capacity in gallons per minute of one line jet pumps, two line jet pumps, submersible pumps, and well pumps of different models and horsepower. This article includes well pump capacity and model example tables from well pump installation manuals provided by the Water Ace Corporation. [permission requested]
Readers of this document should also see the water pump types described at WATER PUMP TYPES & LIFE EXPECTANCY and see our other diagnostic guides for water pumps, wells, motors, in table form:
What is the Pumping Capacity in Gallons per Minute for a 1-Line Shallow Well Jet Pump?
A one-line jet pump can typically raise water from depths of just a few feet (or "0" depth) to about 25 feet in depth, and at water delivery rates of 4 gpm up to as much as 25 gpm depending on the variables we list below the well pump capacity tables shown.
A nice example table of shallow well 1-Line Jet Pump Capacities for 1/2 hp, 3/4, and 1 hp shallow well pumps is provided in the Water Ace Jet Pump Installation Manual and excerpted below to illustrate the factors that determine well pump capacity. Both of the charts below are for one-line jet pumps produced by Water Ace. 1-Line jet pumps intended for shallow well use and made by other manufacturers can be expected to have similar capacities.
The Water Ace charts (shown in part above) make clear that the capacity of a one-line shallow well jet pump to deliver water at a given flow rate varies by these factors:
the depth of the well (the bottom scale in the two charts)
the pump horsepower (the color codes indicate pump model and horsepower HP variation)
The well pump model (the right hand table is for the company's more powerful well pump series of 2-line jet pumps)
The condition of well piping, including pipe diameter, length, number of bends or elbows
The presumption that the entire piping system has no leaks

Watch out: Safety warnings are throughout any pump manufacturer's instructions. Because some pump models are capable of developing internal pressures of more than 100 psi, if your building piping, pressure relief valves, safety controls, wiring, and plumbing are not properly installed, very dangerous conditions including electrical shock, tank explosion, and leaks or floods can occur.
What is the Pumping Capacity in Gallons per Minute for a 2-Line Deep Well Jet Pump?
A two-line jet pump can typically raise water from depths of 30-feet to 80-feet, and at water delivery rates of 4 gpm (gallons per minute) (for a 1/2 hp 2-line jet pump serving an 80 foot deep well) to 16 gpm (for a 1 hp 2-line jet pump serving a 30 foot deep well).
A nice example table of Deep Well 2-Line Jet Pump Capacities for 1/2 hp and 1 hp deep well pumps is provided in the Water Ace Jet Pump Installation Manual and excerpted below to illustrate the factors that determine well pump capacity. Both of the charts below are for 2-line jet pumps produced by Water Ace. 2-Line jet pumps intended for deep well use and made by other manufacturers can be expected to have similar capacities.

What is the Pumping Capacity in Gallons per Minute for a Submersible Deep Well Pump?
A submersible deep well water pump (the pump is physically inside the well and at or close to the bottom of the well piping) can typically raise water from depths of 30-feet to hundreds of feet, and at water delivery rates of 4 gpm 25 gpm depending on the variables that we list below. Submersible well pumps are typically offered in horsepower ratings of 1/2 HP, 3/4 HP, 1 HP, and 1 1/2 HP.
Rated water flow rates for pumps range (by horsepower and model) from a nominal 6 gpm to 35 gpm.
Watch out: installing a higher capacity well pump may indeed give faster water flow and higher water system pressure, but if the pump is not properly matched to the well's safe flow rate (by pump selection or pump controls) you can pump all of the water out of your well, run dry, damage the pump, etc. See Define Safe Yield for a Well
A nice example table of Deep Well Submersible Well Pump Capacities is provided in the Water Ace 4-inch (diameter) Submersible Well Pump Installation Manual and excerpted below to illustrate the factors that determine well pump capacity. We have sharpened the text and provided a larger, more legible table (click to enlarge) than the original.
In selecting a well pump the well depth as well as water flow requirements must be considered. While jet pumps have a pickup placed typically 5-feet above the well bottom, when installing a submersible pump it is placed ten feet above the well bottom (maximum) or ten feet below the draw down limit for the well.
The Water Ace charts (shown in part above) make clear that the capacity of a deep well pump to deliver water at a given flow rate varies by these factors:
the depth of the well (the bottom scale in the two charts)
the pump horsepower (the color codes indicate pump model and horsepower HP variation)

Water Ace asserts that a typical 3-4 bedroom home requires a water delivery rate of 8-12 GPM.
Watch out: the water delivery rate at plumbing fixtures is determined by the water pump as well as building water supply piping and controls. But it is a number independent of the ability of the well itself to deliver a sustained water flow - the well yield. The water delivery rate is also independent of the total quantity of water that can be run before you run out. See How Much Water is In the Well? and see Define Safe Yield for a Well.
Watch out: Safety warnings are throughout any pump manufacturer's instructions. Because some pump models are capable of developing internal pressures of more than 100 psi, if your building piping, pressure relief valves, safety controls, wiring, and plumbing are not properly installed, very dangerous conditions including electrical shock, tank explosion, and leaks or floods can occur.
