# What is the maximum theoretical lift of a well pump?

## What is the maximum theoretical lift of a well pump?

If a pump could produce a perfect vacuum, the maximum height to which it could lift water at sea level would be 33.9 feet, as shown in Example 1. This number is the maximum theoretical lift, but in practice no pump built can produce a perfect vacuum.

## What is lift height for a pump?

Vertical lift For a given pump, the higher water is pumped vertically – the lower the flow; at a some height the flow will be zero. The terms “head height” or “lift” are used to indicate this vertical height, measuring how high the water can be pumped for a particular application.

## How do you size a deep well pump?

The key to sizing a submersible well pump is to calculate the gallons per minute of water required during peak periods. Smith recommends sizing a submersible well pump based on fixture count, which involves counting the fixtures and faucets in a home.

## How deep can a deep well jet pump pump?

25 to 110 feet deep
The shallow well jet pumps draw water from one line situated in wells no deeper than a maximum of 25 feet deep. Deep well jet pumps use two lines, one for pulling the water, and one for pushing the water into the delivery system. Deep well jet pumps can pump water from wells that range from 25 to 110 feet deep.

## How deep can a 1/2 HP well pump go?

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).

## How deep can a pump suck water?

A sufficiently strong pump can lift water as high as you want, it just can’t suck water more than 30 feet up. Hand pumps that work by suction only work if the surface of the water is less than 10 meters below the pump. Having to go more than 30 feet down to hit water is a pretty deep well.

## What size of pump do I need to lift water 100 feet?

Example – Horsepower Required to Pump Water

Power Required to Pump Water (hp)
Volume Flow (gpm) Height (ft)
80 0.101 0.404
90 0.114 0.455
100 0.126 0.505

## How high can a 1/2 HP pump push water?

You can expect a 1/2 HP submersible pump to raise your water up to 10 feet out of the ground. This lift rate makes the 1/2 HP pump ideal for homes closer to sea level.

## Can you oversize a well pump?

SIZING A WELL PUMP The size of a well pump directly affects its efficiency, lifespan and ultimate cost. An undersized pump will result in low water pressure, while an oversized model will consume more energy than necessary. Both scenarios will result in excessive wear on the system.

## Can you use a jet pump on a deep well?

Deep Well Pumps can also be referred to as convertible jet pumps. This means that the pump can be used in either shallow or deep wells. In a shallow well setup, an ejector kit (or jet kit) is built in or attached to the pump. For deep wells, the kit is placed down in the well.

## What depth is considered a deep well?

Drilling a Water Well for household use will usually range from about 100 feet to 500 feet deep, but… When drilling a new well for your home or business, the depth of the well depends on the geology and underground water levels of the area.
