Nist Trio 400V up to 5.6kw

The Borehole nist trio 400V up to 5.6kw, refers to a range of submersible pumps designed specifically for use in boreholes or deep wells. Here’s a detailed description focusing on its features, specifications, and applications:

1. **Application and Use**:
   - **Borehole Pump**: Designed for pumping water from boreholes, which are narrow shafts drilled into the ground to access groundwater.
   - **Water Supply**: Typically used in residential, agricultural, industrial, and municipal applications to extract water from underground sources for various purposes such as irrigation, drinking water supply, and industrial processes.

2. **Motor Specifications**:
   - **Voltage**: Operates on a standard single-phase 220V AC electrical supply, making it suitable for use in residential and small-scale commercial settings where three-phase power may not be available.
   - **Power Range**: Available in a range of motor powers from 0.37 kW (kilowatts) up to 2.2 kW. The choice of motor power depends on factors such as the depth of the borehole, required flow rate, and lift height needed to bring water to the surface.

3. **Construction and Design**:
   - **Submersible Design**: Built to be submerged in water, the pump is installed directly inside the borehole or well casing. This configuration eliminates the need for priming and reduces noise during operation compared to above-ground pumps.
   - **Materials**: Typically constructed from high-quality materials such as stainless steel or corrosion-resistant alloys to withstand the harsh conditions found in boreholes, including exposure to water with varying mineral content.

4. **Features**:
   - **Efficiency**: Designed for high efficiency to minimize energy consumption while maximizing water output.
   - **Reliability**: Engineered for continuous operation under challenging conditions, ensuring a consistent and reliable water supply.
   - **Built-in Protection**: May include features such as thermal overload protection and moisture-sealed electrical components to enhance durability and safety during operation.

5. **Installation and Maintenance**:
   - **Installation**: Usually installed vertically inside the borehole or well casing, with the pump unit positioned below the water level.
   - **Maintenance**: Regular maintenance is essential to ensure optimal performance and longevity. This includes inspecting seals, bearings, and electrical connections, as well as monitoring motor performance and water output to detect any issues early.

6. **Performance**:
   - **Flow Rate and Head**: The pump’s performance characteristics include its capacity to deliver a specific flow rate (in liters per minute or cubic meters per hour) and the maximum head it can lift water, determined by the motor power and pump design.

In summary, the Borehole UNO 220V 0.37—2.2kW range of submersible pumps is designed to provide efficient and reliable water extraction from boreholes or deep wells. It offers durability, energy efficiency, and ease of installation, making it suitable for a wide range of applications where access to groundwater is essential for everyday use or industrial processes.
