Submersible Pump Head Calculator
A submersible pump head calculator helps you find the total head required for your pump system. It ensures proper water flow and prevents pump failure or inefficiency.
Total Dynamic Head (TDH) Calculator
How to Use Submersible Pump Head Calculator
Follow these simple steps to calculate the required head for your pump system:
- Step 1: Enter Vertical Lift (Static Head)
Measure the vertical distance from the water source to the discharge point. - Step 2: Add Friction Loss
Include pipe length, bends, valves, and fittings. Longer pipes increase friction loss. - Step 3: Include Pressure Head (if required)
Convert pressure requirements into head (1 bar ≈ 10 meters). - Step 4: Input Flow Rate
Enter required flow in liters per minute (LPM) or gallons per minute (GPM). - Step 5: Calculate Total Head
The calculator sums all values to give Total Dynamic Head (TDH).
Tip: Always double-check measurements to ensure accurate results.
How to Calculate Submersible Pump Head
The Total Dynamic Head (TDH) is the total resistance a pump must overcome to deliver water from the source to the destination at the required pressure.
Total Dynamic Head (TDH) Formula:
Step-by-Step Example:
Given:
- Static Head = 30 meters
- Pipe Length = 50 meters
- Friction Loss = 5 meters
- Pressure Requirement = 2 bar
Step 1: Convert Pressure to Head
2 bar × 10 = 20 meters
Step 2: Apply Formula
TDH = 30 + 5 + 20
Step 3: Final Calculation
TDH = 55 meters
Result: You need a submersible pump that can handle at least 55 meters of head.

FAQs – Submersible Pump Head Calculator
Pump head is the height a pump can lift water, including pressure and friction losses.
TDH helps you select the correct pump size and avoid underperformance.
Use pipe length, diameter, and flow rate. Many calculators estimate this automatically based on standard tables for pipe materials.
No. Include it if your system requires pressure at the discharge point, such as for irrigation sprinklers or storage tanks.
The pump will not deliver water properly and may overheat, fail, or run outside its design curve, leading to inefficiency.
It depends on your system. Typical residential deep well systems range from 20 to 100 meters, while industrial pumps can handle much higher heads.
No. Total head (TDH) includes vertical height (static head), friction loss in pipes, and any required discharge pressure.
It is highly accurate if you input correct values for vertical lift, pipe friction, and pressure requirements.
