What is 2 Hp Submersible Pump

A 2 hp submersible pump is a powerful pump for drawing water from deep boreholes, wells or tanks to the place of use.

2Hp submersible pump is a pump with 2 horsepower. Horsepower is the power that determines how much water the pump can move.

Submersible pumps are quiet since they work while completely immersed in water.

Types of 2 HP submersible Pump

Solar Submersible pumps – the submersible pump that uses solar energy to draw water from boreholes.

Electric submersible – works on grid electric power to pump water from the borehole.

How Does a Submersible Pump Work?

Submersible pump is built with a motor, impellers and diffusers sealed by a metal casing. When the pump starts, the motor causes the impeller blade to rotate and create a pressure difference. Water flows through the impeller vanes to the diffuser where it is pushed to the surface through discharge pipe.

What Makes a Submersible Pump Effective?

• The motor and pump are sealed so that water cannot enter the motor compartment.
• Cooling is usually provided by the surrounding water, which helps the motor run without overheating (provided it is submerged).
• Often there is a check valve built in or installed on the discharge side to prevent backflow when the pump stops.
• The pump must be sized (in terms of head, flow, pipe diameter, cable size, etc.) to match the requirements of the application.

Performance of 2 HP Submersible Pump

The flow rate drops with increase in the Head or distance to lift water. Look at the table below. Below is performance table of 2 hp submersible pump in different Head.

Benefits of 2 Hp Submersible Pumps

• Robust – Has high head hence can push water to big heights.
• Quiet – pumps water with less noise.
• Energy efficiency – consumes less power to operate.
• Durability – made of long-lasting durable metallic body.

Why 2hp Submersible Pump?

2Hp submersible pump is the reliable pumping solutions. Here are the reasons why.

Depth – deeper boreholes require more powerful pumps to ensure water can be pumped efficiently.

High pumping Distance – high height or vertical distance means a pump with the high head is the solution.

Water requirements – in case of heavy water usage, for example a building with high number of rooms or tenants, a large and strong pump is ideal. The reason to use 2 hp pump is for faster pumping of water to tanks or high-pressure flow.

Considerations When Selecting Submersible Pumps

Water Source

Before you purchase a submersible pump, always check your water source to ascertain whether it matches with the pump type. The ideal pumps for different water applications are as follows:

Clean Water Pumps – narrow submersible water pumps are ideal for moving clean water from boreholes and tanks.

Dirty water – dirty water or drainage water requires drainage pumps which can be available in different models as per the level of dirt.

Sewage water – sewage pumps are used for moving sewage waste. Designed to efficiently pump sewage water waste.

Discharge Height

The discharge height determines how much water the pump can move from the source to the desired height. For example, from the borehole to the raised tank.

Discharge or Flow Rate

The discharge rate is the amount of water the pump can move per unit time, often measured in minutes or hours. Submersible pumps have varying flow rates depending on the horsepower or size.

Outlet size

Pump outlet size matters when choosing a submersible pump to use. The outlet often connects to a delivery pipe which should also be equal to the pump outlet in diameter.

Borehole Diameter

The diameter of the borehole should be considered when choosing the submersible pump. Ensure the pump’s diameter is smaller than the diameter of the well casing.

Installation of 2 HP submersible Pump

Installation of submersible pumps is done by a qualified technician. The installation process is explained in the steps below:

1.        Clean and Prepare the Borehole

Make sure the borehole is free of debris and sediment. Check the diameter of the casing to ensure the pump assembly will fit and lower freely.

2.        Mount Check Valve / Foot Valve

If not built-in, place a check valve in the discharge line (to prevent backflow).

Use a bottom or foot valve if needed.

3.        Secure Discharge and Guide 

Use guide pipes or straps to prevent pump from swaying.

Use vertical alignment to avoid stressing the pipes.

4.        Electrical Wiring / Control Box

Connect power cable (phase, neutral, earth) correctly.

For single-phase motors, ensure capacitor and starter/control box is correctly installed.

Use correct cable gauge to minimize voltage drop.

Include overload protection or thermal protection.

5.        Lower Pump Gently

Use a suitable drop rope or cable (often certified rope).

Lower slowly, avoid bumping sides of borehole.

Keep cable slack (no tension).

6.        Testing / Start-up

With discharge valve closed, turn on power briefly to ensure motor runs and direction is OK.

Then open discharge and check flow and pressure.

Check for leaks, noise, vibration.

7.        Monitoring

Watch current flow, temperature, vibration.

Keep pressure gauge, flow meter if possible.

Applications of 2 Hp Submersible Pumps

Submersible pumps are used for wide range of water needs. They include.

• Domestic water supply from boreholes (homes, small estates)
• Irrigation of gardens, small farms or orchards
• Supplying water for livestock
• Filling tanks and boosting pressure for high pressure house water applications.
• Small industrial processes that require water
• Wells in areas with moderate depth.’
• Draining pools or stagnant water in compounds.
