How to choose a deep well pump in detail?

5 Things to Know Before Choosing a Submersible Pump

1. Well Mouth Size

2. Well Depth

3. The water level in the well is visible from the well mouth.

4. The amount of water in the well.

5. How far is the water delivered?

---------------------------------------------------------------------------------------------------------------------------

Let's take a detailed look at each point for how to choose a deep well pump.

1. Size of the well mouth

LEO submersible pump: 4XR, 4LPS, 4LPY (4-inch well) / 3XR, 3LPS, 3LPY (3-inch well)

2. The depth of the drilled well

Most artesian wells in the Northeast are not drilled very deep, and water is obtained relatively quickly, for example, at 30-40 meters.

3. How many meters from the mouth of the well is the water level that has risen?

 When we look down from the mouth of the well, we can usually see the water level rising up because there is pressure in the well. We measure the water level from the mouth of the well to the rising water level to see how deep it is. Most often, we will find it at 10, 15, or 20 meters.

Formular

Water level from well mouth + pumping distance

(We usually allow a pumping depth of 20 meters or more.)

**Note

Do not lower the pump until it touches the bottom of the well, as the impeller may get stuck in the mud and cause damage. Allow space for the pump. It must be at least 5 meters above the bottom of the well.

	“Suppose we have a well that is 40 meters deep, the water level at the mouth of the well is 15 meters, and the pumping distance is 20 meters.

	That's 15 + 20 = 35 meters, so we should lower the pump to a depth of 35 meters.”

** NOTE

1. Allow for a pumping distance of 15-20 meters or more if drilling a very deep well, such as 100 meters. We can increase the pumping distance to 30-40 meters.

2. Do not lower the pump until it touches the bottom of the well, as the impeller may get stuck in the mud and cause damage. Allow for a pump clearance of at least 5 meters above the bottom of the well.

"A well is 100 meters deep. How deep should the pump be?"

The water level at the well mouth is 30 meters, and the pumping distance is 30 meters (with an extra 30 meters because the drilling is very deep). Therefore, 30 + 30 = 60 meters. We should lower the pump to a depth of 60 meters.

4. Water volume in the well (liters/hour)?

• You can inquire directly with a well driller.

• In the Isaan region, it's typically 4-8 liters per hour.

• You can also check it yourself via the app: BADAN4THAI2.

5. How many meters is the water delivery distance?

Head calculation

Head 10 meters horizontal = Head 1 meter vertical

Therefore, 200 / 10 = 20 meters.

Example

	Drilling a well 40 meters deep, the water level can be seen from the well mouth at 15 meters, sending water 200 meters horizontally into the garden. What head pump should be selected?

Water level at the well mouth: 15 meters + pumping distance: 20 meters = pump depth: 35 meters.

Horizontal delivery distance: 200 meters = Head: 20 meters.

Therefore, the total delivery distance is 35 + 20 = 55 meters (a pump with a Head of 55 meters or more should be used).
